Diallel Analysis for Yield and its Yield Attributing Traits in Capsicum [Capsicum annuum (L.) var grossum Sendt]

The present investigation was carried out to study heterosis and combining ability for yield and its yield attributing traits in capsicum in the year 2011. The experimental material consisted of twelve parents and 66 F 1 S produced in diallel mating design excluding reciprocals. Analysis of variance for combining ability exhibited the significance for gca and sca effects of all the characters studied. The remarkable heterosis for yield and its yield attributing traits was also observed. The high performing crosses for all the characters studied showed that in general these crosses involved high x high, low x low, high x low and low x high general combiners. The low x low crosses giving high sca value may be due to genetic diversity of the parents and non allelic interactions.
