Estimation of heterosis for seed yield and its component traits in red sweet pepper (Capsicum annuum L. var grossum Sendt) grown under protected condition
Abstract
The objectives focuses on estimation of the magnitude of heterosis for seed yield and its component traits taking an example of six diverse lines (Pure and Stable) of sweet pepper (red color) which were attempted in half-diallel fashion excluding reciprocals during Kharif 2017 and evaluated with a cultivar Bombay grown in a greenhouse with natural ventilation. The analysis of variance showed significant differences among parents and crosses for all traits studied. On the basis of heterosis studies, RSPUHF-3 × RSPUHF-2 and RSPUHF-4 × RSPUHF-2 were identified highly significant cross combinations over better parent and standard check for the number of seeds per fruit, seed weight per fruit, thousand seed weight and per cent seed recovery, whereas; the crosses RSPUHF-7 × RSPUHF-1 and RSPUHF-7 × RSPUHF-4 exhibited a higher standard heterosis for seed yield per plant. This study showed a desirable heterosis over better parent and standard check for seed yield and contributing traits and can further directly be identified as a superior F1 s after their validation over different seasons for growing under protected environments or may be utilized in future breeding programmes to obtain desirable segregants for the development of trait specific superior genotypes.
