ThesisItem Open Access Effect of genotype and packaging material on seed storability of soybean (Glycine max L. Merrill)(CSK HPKV, Palampur, 2023-02-09) Kashyap, Rohan; Kapila, R.K.Study on seed storability was carried out by packing the seeds of four soybean varieties i.e., Shivalik, Hara Soya, Palam Soya and Him Soya of Himachal Pradesh in three different packaging materials viz., Polylined Jute bags, High Density Polyethylene (HDPE) bags and Jute bags and storing them under ambient conditions (March 2021 to July 2022) following completely randomized design in three replications. The experimental material was also planted in the field during kharif 2021 following RBD in three replications to evaluate the varieties for 11 agro-morphological traits. Data recorded after bimonthly intervals over a period of 16 months revealed that most of the seed quality parameters viz., per cent germination, rate of germination, field emergence, seedling length, seedling dry weight and seed vigour indices I and II gradually declined, whereas electrical conductivity witnessed an increasing trend with the advancement of storage period. Variety Him Soya performed poorly under storage and was classified as having short seed storability (12 months), whereas Shivalik exhibited seed germination above IMSCS even after 16 months of storage and was classified as having comparatively long seed storability. Remaining 2 varieties exhibited moderate seed longevity (14 months). Among packaging material, soybean seeds stored in Jute bags performed poorly having comparatively short seed storability (12 months), whereas Polylined Jute bags maintained soybean seed germination above IMSCS even after 16 months of storage. In High Density Polyethylene bags (HDPE), soybean seeds exhibited moderate seed longevity (14 months). All four varieties were also characterized for DUS traits, which revealed 11 out of a total of 21 descriptors to be more informative in classification and identification of the four varieties under study. Field evaluation revealed that the mean sum of squares due to genotypes were significant for all agro-morphological traits studied except for harvest index. Variety Shivalik was the best performing variety for yield and related attributes. This study clearly indicated the effect of genotype and packaging material on seed longevity in soybean under ambient storage.ThesisItem Open Access Seed longevity and its association with horticultural traits in broccoli (Brassica oleracea L. var. italica Plenck.)(CSK HPKV, Palampur, 2022-12-13) Sood, Shivam; Kapila, R.K.Study on seed longevity was carried out by packing the seeds of three broccoli varieties of Himachal Pradesh in high density polyethylene (HDPE) bags and storing them under ambient condition (July 2021 to September 2022) following completely randomized design in four replications. The experimental material was also planted in the field during rabi 2021-22 following RBD in five replications to evaluate the varieties for 10 horticultural traits in order to establish an association of seed longevity with important horticultural traits. Data recorded after fixed bimonthly intervals over a period of 14 months revealed that most of the seed quality parameters viz. per cent germination, rate of germination, field emergence, seedling length, seedling dry weight and seed vigour indices I & II gradually declined, whereas electrical conductivity witnessed an increasing trend with the advancement of storage period. Amongst varieties, Palam Vichitra followed by Palam Samridhi exhibited better seed quality parameters as compared to Pusa Broccoli KTS-1 and the seed longevity was inferred from the per cent germination- final count of the three varieties of broccoli after the completion of the storage period of 14 months. After 14 months of seed storage, per cent germination of variety Palam Vichitra was found to be significantly higher followed by Palam Samridhi and Pusa Broccoli KTS-1. Field evaluation and further analysis of variance revealed that the mean sum of squares due to the varieties were significant for all the horticultural traits except plant height and head size index. Under the field conditions, Palam Vichitra was the best performing variety as compared to other two varieties. Correlation of seed per cent germination after 14 months of seed storage showed significant positive correlation with marketable yield per plant, leaf size without leaf stalk and harvest index. A significant negative correlation of per cent germination – final count after 14 months of seed storage with plant height was also recorded. Hence, dwarf varieties/genotypes producing more marketable yield per plant, having more leaf size without leaf stalk and high percentage of harvest index are likely to have seeds with better storage life/seed longevity.ThesisItem Open Access Effect of seed coating with polymer and chemicals on seed storability of maize (Zea mays L.)(Palampur, 2022-11-18) Divya; Dhiman, K.C.The present investigation was done to study the effect of seed coating on seed quality parameters during storage and further to identify the effective seed coating treatment for enhancing seed storability of maize. The seeds of maize variety Bajaura Makka were treated with nine different treatments consisting of polymer, fungicides, insecticide, polymer-fungicides and polymer-insecticide combinations. The treated and untreated seeds were stored in three replications for twelve months after packing in HDPE (High density polyethylene) interwoven non-laminated bags. The evaluation of different seed quality attributes was made at bi-monthly intervals for twelve months (March 2021 - March 2022). The experiment revealed that irrespective of seed coating, the seed deteriorated and the vigour declined with the advancement in storage period. Amongst different seed treatments, seed coated with polymer + vitavax power (containing thiram 37.5% and carboxin 37.5%) @ 2.0 g/kg of seed (T6) was found significantly superior for all seed quality parameters viz., germination (97.30 %), rate of germination (47.40), field emergence (88.60 %), seedling length (37.00 cm), dry matter of seedling (65.73 mg), seedling vigour index - I (3589.00) and seedling vigour index - II (6375.81) which was at par with T5 - vitavax power (containing thiram 37.5% and carboxin 37.5%) @ 2.0 g/kg seed for all the above mentioned seed quality parameters in comparison to untreated control (T1). Hence, combination of polymer with vitavax or vitavax alone can effectively be used to prevent the rapid deterioration of seed during storage period as they maintained the seed quality attributes for twelve months.ThesisItem Open Access Effect of seed treatments with polymer and chemicals on longevity of wheat(palampur, 2022-11-15) Jyoti, Aparna; Dhiman, K.C.The present investigation was done to study the effect of seed treatments on seed quality parameters and further to identify the effective seed treatment for enhancing seed longevity in wheat. The seeds of wheat variety HPW155 were treated with nine different treatments consisting of polymer, fungicides, insecticide, polymer-fungicides and polymer-insecticide combinations. The treated and untreated seeds were stored in three replications for thirty six months after packing in HDPE (High density polyethylene) interwoven non-laminated bags. The evaluation of different seed quality attributes was made at bi-monthly intervals for twelve months (25th - 36th months). The experiment revealed that inspite of seed coating, there is deterioration in seed as well as the seed vigour declined with ageing of seeds. Amongst different seed treatments, seed coated with polymer @ 3.0 ml/kg of seed + vitavax 200 @ 2.0 g/kg of seed (T6 ) was found superior for maintaining quality attributes viz., germination (88.33%), rate of germination (17.86), seedling length (15.11 cm), seedling dry weight (10.42 mg), seedling vigour index- I (1335), vigour index- II (920) and field emergence (69.00%) which was at par with T5 (vitavax 200 @ 2.0 g/kg of seed) for all the above mentioned quality attributes at the end of 36 months of storage in comparision to untreated control (T1). Although these two treatments resulted to maintain the germination (%) above Indian Minimum Seed Certification Standards (IMSCS) upto 36 months of storage, however, it is not advisable to use seeds after 36 months of storage as the field emergence (%) and final plant stand (%) declined significantlyThesisItem Open Access Effect of seed coating on longevity of wheat (Triticum aestivum L.) seeds(Palampur, 2021-11-26) Chaturvedi, Radhika; Dhiman, K.C.The experiment was conducted to evaluate the effect of different seed coating treatments on seed longevity and further to identify the effective seed coating treatment for enhancing seed longevity in wheat seeds. The seeds of wheat variety HPW-155 were coated with nine different treatments comprising of polymer, fungicide, insecticide, polymer-fungicide and polymer-insecticide combinations. The treated and untreated seeds were stored in three replications for twenty-four months after packing in HDPE (high density polyethylene) interwoven non-laminated bags. The evaluation of seed quality parameters was made at bi-monthly intervals for twelve months (13th to 24th months). The experiment revealed that irrespective of seed coating, seed deteriorated and the vigour declined with aging of seeds. Amongst various treatments, seed coated with polymer @ 3 ml per kg of seed + vitavax 200 @ 2 g per kg of seed (T6) was found superior for quality parameters viz., germination per centage (93.00%), speed of germination (18.45), seedling length (16.06 cm), seedling dry weight (0.0116 g), seedling vigour index - I (1494), vigour index - II (1.079) and field emergence (82.00%) at the end of 24 months of storage over untreated control (T1). Hence, combination of polymer with vitavax can effectively be utilized to prevent the rapid deterioration of the seed during storage thereby maintaining the quality for a longer period of time.ThesisItem Open Access Effect of integrated nutrient management on seed yield and quality of wheat (Triticum aestivum L.) under mid hill conditions of Himachal Pradesh(Palampur, 2021-11-27) Thakur, Manisha; Kataria, R.K.A field experiment was conducted during the Rabi season 2020-21 at the Experimental Farm and laboratoryof the Department of Seed Science and Technology, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, to study the effect of integrated nutrient management on seed yield and quality of wheat (Triticum aestivum L.) under mid hill conditions of Himachal Pradesh. The experiment consisted of ten treatments viz. T1 (100% RDF (120:60:30 kg/ha)), T2 (FYM @ 10t/ha + 75%RDF), T3 (FYM @ 10t/ha + 100%RDF), T4 (Vermicompost @ 5t/ha + 75% RDF), T5 (Vermicompost @ 5t/ha + 100% RDF), T6 (FYM @ 5 t/ha + Vermicompost @ 2.5 t/ha + 75% RDF), T7 (FYM @ 5t/ha + Vermicompost @ 2.5t/ha + 100% RDF), T8 (FYM @ 5t/ha + Vermicompost @ 2.5t/ha), T9 (FYM @ 5t/ha + Fortified Vermicompost @ 2.5t/ha) and T10 (FYM @ 10t/ha + Vermicompost @ 5t/ha). These ten treatments were tested in randomized block design with four replications. The results revealed significantly highest growth parameters (plant height (92.0 cm) and dry matter accumulation (1141.8 g/m²)), yield attributes (number of tillers/m² (240.55), number of spikelets/m² (218.30), spike length (13.0 cm), spikelets/spike (16.5), seeds/spike (36.6) and 1000 seed weight (45.82g)), seed yield (3925.8 kg/ha) and seed quality parameters (seedling length (18.7 cm), seedling dry weight (188.0 mg), vigor index-I (1789.4) and vigor index-II (17989.7)) was recorded with the application of vermicompost @ 5t/ha along with 100% RDF treatment T5 which was at par with treatment T3 (FYM @ 10t/ha + 100% RDF) for most of the above mentioned parameters. Further, data on economic part revealed that though highest gross return (Rs.146325.9) was recorded with treatment T5, but higher net return (Rs.89681.1) and B:C ratio (1.65) was recorded for treatment T3 as compared to T5. Hence, it can be concluded that both treatments viz. T5 and T3, can be recommended for quality seed production of wheat in mid hill conditions of Himachal PradeshThesisItem Open Access Seed longevity and its association with agronomic traits in wheat (Triticum aestivum L.)(Palampur, 2021-11-12) HARSHITA; KAPILA, R.K.The present study entitled “Seed longevity and its association with agronomic traits in wheat (Triticum aestivum L.)” was carried out by packing the five wheat varieties of Himachal Pradesh in HDPE bags and storing them under ambient storage conditions using completely randomized block design in seed technology laboratory (August 2020- August 2021) to assess seed longevity in wheat seeds. Following RBD in three replications to evaluate 11 agro-morphological traits, the experimental material was planted in the field during rabi 2020-21. Data recorded over 12 months after fixed bimonthly intervals revealed that most of the seed quality parameters viz., germination per cent- first and final count, rate of germination, field emergence, dry matter of 10 seedlings, vigour index-I and vigour index-II gradually declined, whereas electrical conductivity witnessed an increasing trend with the advancement of storage period. Seed longevity of five wheat varieties of Himachal Pradesh inferred from the germination- final count of the present study revealed maintenance of germination- final count of more than 85% in variety HPW 349 upto 10 months and in other 4 varieties beyond 12 months of storage. Aforesaid varieties were also characterized for DUS traits that revealed 30 out of total 34 descriptors to be more informative in identification and classification of five varieties under study. Field evaluation and further analysis of variance revealed that the mean sum of squares due to genotypes were significant for all the agro-morphological traits except spike length. High heritability (75-100%) coupled with high genetic advance was found for days to 50% heading, plant height, peduncle length, days to physiological maturity, harvest index and number of grains per spike traits. Variety, HPW 249 was the best performing variety for yield and related traits. Correlation of germination after 12 months interval with 11 agromorphological traits revealed a strong and positive association of seed longevity with number of grains per spike, test weight, biological yield per plant, seed yield per plant and productive tillers per plant.Thereby the possibility of designing an ideotype of wheat through selection for more number of tillers per plant, more number of grains per spike and test weight accompanied with higher biological yield per plant and seed yield per plant. Based on association analysis, this study presents an indirect selection criterion based on some easily scorable agro-morphological parameters which have strong association with seed longevity.ThesisItem Open Access EFFECT OF SOWING PATTERN AND SEED RATE ON THE YIELD AND QUALITY OF WHEAT (Triticum aestivum ) SEED IN MID HILL CONDITIONS(CSHHPKV Palampur, 2017-07-18) KUMARI, PARINITI; Kataria, R.K.Wheat (Triticum aestivum) is the most important staple food of the majority of world’s population. It is the most important crop of Himachal Pradesh during winter season in low and mid hills of the State. Manipulation of agronomic practices such as planting pattern/geometry and seed rate are considered to be foremost step to achieve proper distribution of plants over cultivated area, thereby better utilization of above and below ground natural resources towards increasing yield. A field and laboratory investigation was undertaken to study the effect of different planting patterns and seed rates on seed production and its quality in wheat by evaluating the yield and quality parameters. The experiment with twelve treatment combinations comprising of four planting patterns (15 cm, 23 cm, 15 x 15 cm and 23 x 23 cm) and three seed rates (100, 120 and 140 kg/ha) was conducted in Randomized Block Design with three replications during Rabi 2015 at the experimental farm of department of Seed Science and Technology. The observations recorded revealed that planting patterns of 23 x 23 cm resulted in significantly more plant height, leaf area index, number of spikes/m2 , spike length, number of spikelets per spike, number of grains per spike, biological yield, seed yield, seed recovery percentage, 1000 seed weight and vigour index over other planting patterns. No significant effect of different planting patterns on number of shoots/m2 after complete emergence, days to 50 % heading, harvest index and germination percentage was observed. 140 kg/ha seed rate produced significantly higher number of shoots per m², leaf area index, number of spikes per m², biological and seed yield over 120 kg/ha and 100 kg/ha seed rate.ThesisItem Open Access CHARACTERIZATION OF INTERSPECIFIC DERIVATIVES OF LENTIL FOR MORPHOLOGICAL AND SEED QUALITY PARAMETERS(CSHHPKV Palampur, 2020-08-30) THALYARI, JEENIA; Jai DevThe present investigation entitled “Characterization of interspecific derivatives of lentil for morphological and seed quality parameters” was undertaken to classify lentil genotypes using DUS guidelines and to identify the promising ones for characters related to yield and seed quality. The research involved the analysis of 29 recombinant inbred lines (RILs) in randomized block design (RBD) with three replications along with two checks viz., Markanday and Vipasha. The lines were evaluated at Research Sub Station, Berthin, District Bilaspur (HP) and Department of Seed Science and Technology, CSK HPKV, Palampur, District Kangra (HP) during rabi 2019-20. Using DUS characterization, the variability in the expression of 13 distinguishing traits was observed at seed and plant levels. Seed size, seed colour, foliage colour, anthocyanin colouration on stem, leaflet size, plant growth habit and plant height were found to be the most useful characters for sound classification of lentil genotypes. Sufficient variability was observed for almost all yield related attributes and seed quality parameters. PCV values higher than GCV indicated that the apparent variation was due to the influence of both genotype and environment. High genetic advance as percentage of mean along with high heritability was observed for pods per plant, seeds per pod, biological yield per plant (g), seed yield per plant (g) and harvest index (%) suggesting their potential towards response to selection. Most of the RILs showed good response towards Fusarium wilt, indicating the transfer of disease resistant genes from the parents. Cluster analysis grouped the genotypes into six clusters with CI RIL 9 and C2 RIL 79 being the most diverse. C1 RIL 43, C1 RIL 58, C1 RIL 53, C1 RIL 62, C1 RIL 65 and C2 RIL 75 surpassed the best check ‘Vipasha’ for most of the traits under study. Out of these RILs, C1 RIL 65 proved to be a promising genotype for yield related attributes and C1 RIL 58 performed well for all seed quality parameters.
