Out of three NILs of IR 64, IET 20667 showed maximum genetic similarity (0.74) with recurrent parent IR 64; while for Swarna, all three lines exhibited moderate degree of genetic similarity ranging from 0.63 to 0.67.

Populations for AB-QTL analysis commonly use exotic or wild germplasm as the donor and elite germplasm as the recurrent parent. The QTL analysis is conducted in the B[C.sub.2] or B[C.sub.3] generation to reduce the frequency of deleterious donor alleles.
