✦ Synopsis

Studies on inheritance of resistance to CGMMV showed that resistance was governed by polygenes with recessive nature . Out of 15 crosses studied, 10 were found to be interacting . All the interacting crosses (except one Phoot X Harela) showed duplicate type of epistasis . Kachri X Phoot (R X R type) cross exhibited heterosis in F1 and transgressive segregation in F 2 for resistance . Studies pointed out the need to exploit this F, further to develop a new breeding line with higher level of resistance than both the parents .
