Heterosis 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 annuumL. var. grossum Sendt.)” was carried out at Vegetable Research and Demonstration Block of Uttarakhand University of Horticulture and Forestry, Bharsar, during 2016-2017. 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 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× SolanBharpur (16.76%) and SolanBharpur×LC-10 (97.08%). 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× SolanBharpur and SolanBharpur×LC-10 can be recommended for commercial cultivation after multi-location testing. | Heterosis studies for yield and horticultural traits in Capsicum (Capsicum annuum L. var. grossum Sendt.)
