Heterosis and combining ability studies on important biochemical traits of brinjal (Solanum melongena L.)

Abstract

The experiment was under taken to asses breeding behavior of eight parental lines for important biochemical traits of brinjal like, total soluble solids content, vitamin C content and total phenol content in edible fruits. IBWL-1 x PRLP-1, PS x PB-101 and PB-6 x PB-101 cross combinations were identified as positive significant for T.S.S. While PLP-1 x PB-101, PR x PB-101 and PPR x IBWL-1 were yielded with significantly high vitamin C. Significant negative and desirable heterosis for total phenol content reported in PPR x IBWL-1, PS x PR and PS x PLP-1 cross combinations. Parental lines PS, PB-101 and S.g were identified as best general combiners for traits like total soluble solids content, vitamin C and low total phenol content respectively. Specific combining ability studies revealed specific cross combinations for these traits viz., PS x PB-101 for T.S.S, PLP-1 x PB-101 for vitamin C and PPR x IBWL-1 for low total phenol content.
