| dc.description.abstract | The present investigation entitled “Heterosis and Combining Ability Studies for Yield and other Horticultural Traits in Chilli (Capsicum annuum L. var. acuminatum Fingerh.)”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 chilli 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 (Arka Harita) was observed for all the traits under study. Nine crosses over better parent and three crosses over the standard check exhibited positive and significant heterosis for yield per plant. The cross Byadgi Dabbi × G-4(60.06%) exhibited maximum heterosis over the better parent and Byadgi Dabbi × Arka Lohit(24.24%) over standard check. Further, the parent Arka Lohit emerged as good general combiner for plant height, fruit diameter, stalk length ,stalk weight, number of fruits per plant, fruit yield per plant and fruit yield per plot. Whereas, the Byadgi Dabbi was identified as good general combiner for days to 50% flowering,days to first fruit harvest, average fruit weight and high ascorbic acid content. Similarly Pant C-1 was good for number of primary branches and high capsaicin content. The highest specific combining ability effect in plant stem girth, fruit length ,days to 50% flowering, average fruit weight , average number of fruits per plant, capsaicin, fruit yield per plant and plot was observed in cross Arka Lohit × Pant C-1. 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, Byadgi Dabbi × Arka Lohit, Byadgi Kaddi × Arka Lohit and Byadgi Dabbi × G-4 can be recommended for commercial cultivation after multi-location testing. | en_US |
