| dc.description.abstract | Fruits node-1 and fruit orientation are economically important fruiting habit traits in chilli. Fruiting habit(s) could be solitary-erect (SE), solitary-pendant (SP), clustered-erect (CE) and clustered-pendant (CP). Farmer preferences for fruiting habit traits varies from region to region. An understanding of genetics of fruiting habit traits help accelerate breeding chilli cultivars with farmer-preferred desired combination of fruiting habit traits in high fruit yield background. Nine diverse genotypes contrasting for fruiting habit traits were crossed to develop fourteen F1 hybrids of seven distinct fruiting habit trait combinations, namely CE × SE, CP × SP, CE × CP, CE × SP, CP × SE, SE × SP and SE × SP during 2015 rainy season; The F2 and backcross generations (B1 and B2) were developed during 2016 summer. F1, F2, B1 and B2 of all the seven distinct types of crosses were evaluated and pattern of segregation for fruiting habit traits was recorded during 2016 and 2017 rainy seasons at the experimental plots of the Department of Genetics and Plant Breeding, University of Agricultural Sciences, Bengaluru. Results indicated bi-allelic monogenic inheritance of fruits node-1 and fruit orientation with solitary being dominant over clustered and pendant being dominant over erect orientation, respectively. Genes controlling fruits node-1 and orientation of fruits segregated independently. Magnitude and direction of additive genetic effects [a] and dominance genetic effects [d] and additive genetic variance (σ 2 A) and dominance genetic variance (σ 2 D) varied with the genetic background of the crosses and traits. Non-significant differences between fruiting habit classes such as (1) S & E, (2) S & P and (3) CE & CP for fruit yield and its contributing traits in both F2 and back cross populations and one pair of near isogenic lines (NILs) indicated the lack of influence of fruiting habit traits on fruit yield and its contributing traits. | en_US |
