    GENETICAL STUDIES IN CHERRY TOMATO (Solanum lycopersicum var. cerasiforme) CULTIVARS UNDER PROTECTED ENVIRONMENT
    (CSKHPKV, Palampur, 2018) Shiksha; Sharma, Parveen
    Fourteen genotypes of cherry tomato were evaluated under modified naturally ventilated polyhouse at the Experimental Farm, Department of Vegetable Science and Floriculture, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur during autumn winter season, 2017-2018 for marketable yield and its component traits to assess the morphological diversity among the genotypes. Based on the mean performance, genotypes viz. Solan Red Round, IC-383117 and EC-383109 were found superior for marketable fruit yield, number of marketable fruits per plant, number of fruits per cluster, number of nodes per plant and plant height among all the genotypes evaluated. Sufficient genetic variability was observed for almost all the traits studied. High PCV, GCV, heritability and genetic advance were observed for number of fruits per cluster and lycopene content. Hence, it was inferred that there is better scope for improvement of these traits through direct selection. Marketable yield per plant was positively and significantly correlated with number of fruits per cluster, number of fruits per plant, number of nodes per plant and plant height at both phenotypic and genotypic level. Number of marketable fruits per cluster had the maximum and significant direct contribution towards marketable yield per plant followed by plant height. However, fruit yield per plant was also significantly increased by indirect effects of number fruits per plant, number of nodes per plant and plant height via number of fruits per cluster. As number of fruits per cluster, plant height, number of fruits per plant and number of nodes per plant have high selection index, therefore due emphasis should be given to these characters in selection programme for improvement of cherry tomato to evolve high yielding genotypes from consumers’ perspective.

    STUDIES ON INBREEDING DEPRESSION AND COMBINING ABILITY IN GARDEN PEA (Pisum sativum L.)
    (CSKHPKV, Palampur, 2018-06-22) Sandeep Kumar; Katoch, Viveka
    The present investigation entitled “Studies on inbreeding depression and combining ability in garden pea (Pisum sativum L.)” was carried out at the Vegetable Research Farm, Department of Vegetable Science and Floriculture, CSK HPKV Palampur during rabi 2016-17 to derive information on extent of residual heterosis, inbreeding depression and nature of gene action following line × tester analysis. The experimental material comprised of five diverse lines of pea viz., Line 12, Line 13, Line 14, Line 15 and Line 17; three testers namely, Matar Ageta, Palam Triloki and Arkel and F2 generation of 15 crosses. Cross L13 × T2 exhibited maximum significant negative residual heterosis over Line12 (BP) and Matar Ageta (SC1) for days to 50% flowering and days to first picking. Cross L17 × T2 was most promising for pod yield per plant and related traits like number of pods per plant and number of primary branches per plant. Estimates of GCA effects among parental lines revealed that Line 17 was the best general combiner for days to 50% flowering, pod length, number of pods per plant and pod yield per plant. Line 14 was the best general combiner for pod length and number of seeds per pod. Line 13 was the best general combiner for days to 50% flowering and total soluble solids. Among testers, Palam Triloki (T2) was the best general combiner for days to 50% flowering and days to first picking. The estimates of SCA variances were much higher than the GCA variances for all the characters studied except for days to first picking and pod yield per plant, indicating importance of non-additive gene effects. On the basis of mean performance and residual heterosis cross L13 × T2 was found to be the best with respect to earliness and pod length. Cross L17 × T2 exhibited highest number of pods per plant and pod yield per plant.

    GENETICAL STUDIES FOR FRUIT YIELD AND RELATED TRAITS IN BACTERIAL WILT RESISTANT GENOTYPES OF TOMATO (Solanum lycopersicum L.)
    (CSKHPKV, Palampur, 2018-06-08) Singh, Paras; Chadha, Sanjay
    Tomato (Solanum lycopersicum L.) is one of the most widely produced and consumed vegetables in the world both for fresh market and processed food industries. Its cultivation in commercial growing pockets of Himachal Pradesh is severely affected due to bacterial wilt disease caused by Ralstonia solanacearum. Resistant genotypes have been developed at various research centres, located within the country and abroad but these genotypes were not found suitable for growing in Himachal Pradesh as these are lacking in one or other characteristics. The present investigation entitled “Genetical studies for fruit yield and related traits in bacterial wilt resistant genotypes of tomato (Solanum lycopersicum L.)” was carried out by evaluating 29 bacterial wilt resistant genotypes of tomato (developed in the Department of Vegetable Science and Floriculture, CSK HPKV, Palampur) along with three bacterial wilt standard checks viz., Arka Vikas (National check), Palam Pride and Palam Pink (State checks) with the objectives to assess the magnitude of the genetic variability in bacterial wilt resistant genotypes of tomato, to find out the inter-relationship among component traits and direct and indirect contribution on marketable fruit yield, and to identify the most promising genotypes. These genotypes were evaluated in Randomized Complete Block Design with three replications in summer-rainy season, 2017 at the Vegetable Research Farm of the Department of Vegetable Science and Floriculture, COA, CSK HPKV, Palampur. To ascertain the severity of the disease, two susceptible checks, Roma and Arka Meghali were planted at every alternate 11th row in the experiment. All the genotypes and resistant checks exhibited a high degree of resistance level (>90% plant survival). The maximum marketable yield per plant was produced by the genotypes HPBT-8 (1.44kg) and was significantly at par with HPBT-17 (1.42kg), HPBT-23 (1.38kg), HPBT-2 (1.29kg) and also with the standard check Palam Pink (1.36kg). These top performing genotypes also excelled in other horticultural traits. For most of the characters high to moderate PCV and GCV estimates along with high heritability and genetic advance were observed. The estimates of PCV were higher than corresponding GCV for all the characters studied which indicated that the apparent variation is not only due to genotypes but also due to the influence of environment. Marketable yield per plant was positively and significantly correlated with gross yield per plant, total fruits per plant, marketable fruits per plant, pericarp thickness and average fruit weight, whereas negatively and significantly correlated with titrable acidity and ascorbic acid. Days to 50 per cent flowering had significant positive association with marketable yield per plant at genotypic level. Path coefficient analysis revealed that gross yield per plant and total fruits per plant had the maximum positive contribution towards marketable yield per plant at phenotypic and genotypic level, respectively. Hence, these traits require special attention to improve upon marketable yield and other component traits.

    GENETIC ASSESSMENT FOR FRUIT YIELD AND HORTICULTURAL TRAITS IN OKRA (Abelmoschus esculentus (L.) Moench)
    (CSKHPKV, Palampur, 2018-07-19) Samim, Samiullah; Sood, Sonia
    Okra (Abelmoschus esculentus (L.) Moench) also called as lady‟s finger or bhindi is one of the most common, export-oriented and principal vegetable crops grown all the year round in the country including low and mid hills of Himachal Pradesh. Development of high yielding and yellow vein mosaic virus (YVMV) resistant varieties is the major necessity in this crop. Interspecific and intervarietal hybridization followed by selection have been adopted to develop high yielding and YVMV resistant varieties. However, a frequent breakdown of YVMV resistance of most of the resistant varieties has taken place and this needs immediate attention. Hence, identification and development of new improved disease resistant cultivars is very important to further boost up the production and productivity of the crop. Based on these considerations, the present investigation was, therefore, undertaken in 19 diverse genotypes of okra evaluated in Randomized Block Design with three replications at Palampur during summer-rainy season, 2016 to assess the genetic parameters of variability and to understand the inter-relationships among horticultural traits and fruit yield. The estimates of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were high for first fruit producing node. Moderate PCV and GCV were noticed for days to 50 per cent flowering, plant height, fruit yield per plant, fruits per plant, nodes per plant and internodal length. High heritability along with high genetic advance were observed for days to 50 per cent flowering, fruit yield per plant, fruits per plant and nodes per plant indicating the role of additive gene action for their inheritance. Hence, these characters could be improved through direct selection. High to moderate heritability with low genetic advance was recorded for days to first picking, harvest duration and dry matter, indicating the non-additive gene activity, these could be improved through hybridization. Among visually observed characters, green, dark green, yellowish green and dark red fruit colour at immature stage, downy to slightly rough pubescence and 5 ridges per fruit were recorded in the genotypes evaluated. The association studies revealed that the selection based on plant height, harvest duration, fruits per plant, nodes per plant, fruit length and average fruit weight would be fruitful and rewarding for effective improvement of fruit yield per plant. The genotypes 9801, Palam Komal, Hisar Unnat, Parbhani Kranti, VRO-6 and VRO-4 were found to be promising for fruit yield per plant along with other desirable quantitative and quality traits. Thus these genotypes can be directly used after multilocation testing.

    CMS AND SI BASED HETEROSIS AND COMBINING ABILITY STUDIES UNDER ORGANIC AND INORGANIC CONDITIONS IN CABBAGE (Brassica oleracea var. capitata L.)
    (CSKHPKV, Palampur, 2018-07) Nitish Kumar; Chadha, Sanjay
    The present investigation was undertaken to estimate the extent of per se performance and heterosis, work out the nature and magnitude of gene action and to identify potential parental lines and cross combinations on the basis of combining ability under organic and inorganic conditions. Eight lines viz., IIS CMS, IIIM CMS, GA(P) M CMS, III-1-1, I-4-6, I-4-4, I-4-3 and SC-5-5-4 and three testers viz., Glory-7, KGAT-1 and E-1-1&-2, and their 24 F1s developed as per line × tester mating design alongwith two standard checks (Varun and KGMR-1) were evaluated in a randomized block design with three replications at organic and inorganic conditions during rabi seasons of 2015-16 and 2016-17. The analysis of variance indicated significant differences among genotypes (G) for marketable head yield and other component traits in all the environments. Significant differences for environment (E) and G × E interaction for most of the traits indicated a definite role of environment on the performance of genotypes/crosses. Variances due to lines, testers and line × tester and their interaction with environment were significant for most of the traits under organic and inorganic conditions, indicating the importance of testing parents as well as cross combinations across environments. The parental lines viz., IIS CMS and I-4-3 under organic conditions and III-I-I and I-4-6 under inorganic conditions, whereas, the testers KGAT-1 and Glory-7 under organic conditions and inorganic conditions, respectively were the most promising general combiners for marketable head yield and component traits. On the basis of specific combining ability, heterosis and per se performance for marketable head yield and related traits, cross combinations viz., I-4-4 × Glory-7, I-4-3 × KGAT-1 and III-I-I × KGAT-1 under organic conditions and I-4-6 × Glory-7, III-I-I × KGAT-1 and IIIM CMS × E-1-1&-2 under inorganic conditions were the most promising as they surpassed the standard checks (Varun and KGMR-1). Overall, III-I-I × KGAT-1 was the most promising cross combination among the top hybrids under organic and inorganic conditions. For most of the traits important from commercial point of view, there was preponderance of non-additive gene action, which reaffirms the importance of hybrids in cabbage. There was differential response of different genotypes to organic and inorganic conditions. This necessitates the separate breeding programme to identify potential genotypes responsive to organic and inorganic input conditions.

    (CSKHPKV, Palampur, 2018-07-19) Rahman, Aziz- Ur; Katoch, Viveka
    The present study was conducted under mid hill conditions of Himachal Pradesh at the Experimental Farm of Department of Vegetable Science and Floriculture, CSK HPKV, Palampur during rabi seasons 2015-16 and 2016-17 to identify high yielding powdery mildew resistant line(s). The experiment was laid out in randomized complete block design (RBD) with three replications under two farming conditions (conventional and natural farming conditions) utilizing seven lines viz., APL-55, APL-69, APL-80, APL-64, APL-84, Line 1-2-SPS5, Line 1-2-SPS11, along with four checks namely, Azad Pea-1, Lincoln, Punjab-89 and Palam Priya. Data was recorded on yield and related horticultural traits including powdery mildew incidence. Experimental findings revealed that higher yield was recorded under conventional farming condition in comparison to the natural farming condition. Under conventional farming conditions, Line 1-2SPS5 gave significantly highest yield (211.50 q/ha) followed by Line 1-2SPS11 (206.00 q/ha). In natural farming condition higher pod yield was noted in Line 1-2SPS5 (78.00 q/ha) followed by Line 1-2SPS11 (72.33 q/ha). Line 1-2-SPS5 exhibited resistance to powdery mildew disease and was also superior with respect to yield contributing traits like pod length, number of seeds/pod, number of pods/plant, pod yield/plant(g) and pod yield (q/ha) under both conventional and natural farming conditions.
