Summary

Study of linkage was carried out in the F₂ population of four crosses involving five parents, A.S. 158, Dodania, Vidul, Redar and male sterile CK-60.

Three new gene loci, Rc rc (coleoptile colour red/green) Bsr bsr (basal spikelet colour red/white) and U u (Grain shape-umbonate/round) were inden-tified for the first time. The locus Rc was placed in between P and Rs at a distance of 9.40 from P in linkage group No. 3.

The remaining two loci, Bsr and U, were found to be in linkage group No. 8, the position of the Bsr being in between Ra and Rsg at a distance of 6.66 from Ra. U was observed to lie at a distance of 40.4 from R but away from Ra.
