ThesisItem 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 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.ThesisItem Open Access SEED LONGEVITY AND ITS ASSOCIATION WITH AGRONOMIC TRAITS IN SOYBEAN (Glycine max L. Merrill)(CSKHPKV. Palampur, 2020-08-31) SINGH, SHREYA; Kapila, R. K.Study on seed longevity was carried out by packing the seeds of seven soybean varieties of Himachal Pradesh in high density polyethylene (HDPE) bags and storing them under ambient condition (Jan 2019 to May 2020) following completely randomized design in four replications. The experimental material was also planted in the field during kharif 2019 following RBD in three replications to evaluate the varieties for 12 agro-morphological traits in order to establish an association of seed longevity with important agronomic traits. Data recorded over a period of 16 months after fixed bimonthly intervals 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. Varieties, Palam Early Soya 1 and Him Palam Hara Soya 1 performed poorly under storage and were classified as having short seed longevity (12 months), whereas PS 1556 exhibited seed germination above IMSCS even after 16 months of storage and was classified as having comparatively long seed longevity. Remaining 4 varieties exhibited moderate seed longevity (14 months). Aforesaid varieties were also characterized for DUS traits that revealed 11 out of a total of 21 descriptors to be more informative in classification and identification of the seven 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 12 agro-morphological traits studied. High heritability coupled with high genetic advance was found for 100-seed weight and harvest index. Variety, PS 1556 was the best performing variety for yield and related attributes. Correlation of seed germination after 8 and 16 months intervals as well as of seed longevity, with 12 agro-morphological traits revealed a strong and positive association of seed longevity with number of pods per plant, seed yield per plot and seed yield per ha. Simultaneously a very strong and negative association of seed longevity was detected with test weight and number of branches per plant indicating thereby the possibility of designing an ideotype of soybean through selection for more number of pods per plant, less number of branches per plant and lesser 100-seed weight accompanied with higher seed yield. The study presents choice of indirect selection criteria based on some easily accessible agromorphological traits for improving seed quality of soybean under storage.
