Utilizing wild relative ((Solanum viarum) as resistant source to shoot and fruit borer in brinjal (Solanum melongena Linn.)

Brinjal (Solanum melongena Linn.) has very important place in Indian curries and also in China, Japan and Southern Europian recipies. High yield combined with good quality as well as resistance to shoot and fruit borer in a brinjal variety is the ultimate aim in the most of the brinjal breeding programme. Solanum viarum is closely related to Solanum melongena and both are cross compatible. Therefore hybridization was undertaken in brinjal (Solanum melongena L.) with Solanum viarum to transfer the resistance trait of shoot and fruit borer and combine the resistance trait with high yield of brinjal.. Hybridization was made and F1 hybrid plants were raised. Subsequently in each generation selfing was done followed by selection to obtain F9 generation. In F9 generation selection was done in the plants with high marketable yield along with very low or negligible shoot and fruit borer infestation. The direct derivatives of EP 65 x Solanum viarum were evaluated upto F9 . Two recombinant progenies viz., 7 and 9 were selected in F9 generation for carrying forward to the next generation based on their high marketable yield and the least infestation of shoot and fruit borer. Molecular study with RAPD primers also revealed the introgression of the genes from donor parent Solanum viarum to brinjal.
