Cyclic illustrations of epistatic QTLs of Savitri NILs for grain yield under various levels of drought stress (a) GYSS: chromosome 2 (RM71-RM290,50 cM) and chromosome 3 (RM7-RM251 67 cM, RM319-RM55 167 cM and RM55-RM570,182 cM) have shown epistatic interaction with background loci of chromosomes 3,7 and 11 (b) GYMS: chromosome 4(RM537-RM335) and chromosome 10(RM244-RM239) was interacted negatively with a common genetic loci (RM136-RM275) on chromosome 6 (c,d) GYMS and GYSS of high yielding NILs: no significant interactions was found (e) GYNS: no interaction.
