    Heterosis and Combining Ability Studies for Yield and Horticultural Traits in Capsicum (Capsicum annuum L. var. grossum Sendt.)

    The present investigation entitled “heterosis and combining ability studies for yield and horticultural traits in capsicum (Capsicum annuum L. var. grossum Sendt.)” was carried out at Vegetable Research and Demonstration Block of Uttarakhand University of Horticulture and Forestry, Bharsar, during 2015-2016. The experiment was laid out in a Randomized Block Design (RBD) with three replications. Six diverse capsicum lines were crossed in a diallel fashion (excluding reciprocals) to obtain fifteen cross combinations to study heterosis and combining ability for yield and other horticultural traits. Significant differences were observed among genotypes for all the traits studied. Significant heterobeltiosis was observed in desirable direction for all traits. Similarly, significant increase or decrease heterosis over check (Indham Bharat) was observed for all the traits under study. Eleven crosses over better parent and three crosses over the commercial check exhibited positive and significant heterosis for yield per plant. The cross California Wonder × LC-10 (18.49%) exhibited maximum heterosis over the better parent and commercial check, followed by California Wonder × Solan Bharpur (16.76%) and Solan Bharpur × LC-10 (97.08%). Further, the parent California Wonder emerged as good general combiner for plant height, fruit diameter, fruit pericarp thickness, shelf life and fruit yield. Whereas, the Arka Mohini was identified as good general combiner for plant stem girth and average fruit weight. Similarly Solan Bharpur was good for number of fruits per plant. EC802552 was identified as good general combiner for days to 50% flowering, days to first fruit harvest, fruit length and ascorbic acid content, and LC-8 for number of primary branches. The highest specific combining ability effect in fruit yield was observed in cross Arka Mohini × LC-10. Whereas, different cross combinations showed the good specific combining ability effects in different horticultural traits in desirable direction. Hybrids performed better in yield and other horticultural traits that opened the way for further evaluation and release as hybrids. Hence, California Wonder × LC-10, California Wonder × Solan Bharpur and Solan Bharpur × LC-10 can be recommended for commercial cultivation after multi-location testing.

    The present investigation entitled “Genetic evaluation of cucumber (Cucumis sativus L.) genotypes for yield and yield attributing traits” was carried out at the Vegetable Production cum Demonstration Block, VCSGUUHF, College of Horticulture, Bharsar (Uttarakhand) during the period, April to September 2015. Nineteen diverse genotypes of cucumber (Cucumis sativus L.) were collected from different indigenous sources and planted in Randomized Complete Block Design with three replications and were assessed to know the nature and magnitude of variability, heritability, genetic gain and genetic divergence for yield and horticultural traits. The results showed significant variation among different genotypes for all the traits under study. Genotype Bharsar LC-1 had maximum total yield followed by Chinese Hytivus, K-75, Gherkin and Arunachal collection. Vine length, number of branches, number of nodes, leaf area, inter-nodal length, average fruit weight and TSS was also obtained maximum in Bharsar LC-1 followed by Arunachal collection.Genetic analysis indicated that phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) in all of the attributes studied. High heritability (broad sense) estimates coupled with high genetic gain were observed for yield and other horticultural traits. Linear correlation analysis showed that number of branches, vine length, leaf area, days to first female flower, average fruit weight and TSS were significantly and positively associated with yield both at genotypic and phenotypic level. Path coefficient analysis revealed that number of branches, pericarp thickness, fruit per picking, fruit length, average fruit weight, node bearing first female flower, leaf area, maturity duration, days to first female flower had positive direct effect on yield. Further, divergence studies indicated that hybridization between genotypes from cluster II and III can be utilized for getting the superior recombinants in segregating generations.
