Abstract

Monosomic lines of Kalyansona were crossed with DWR-39 and the F₂ analysis was employed to locate genes governing two quantitative characters to different chromosomes. This analysis led to the location of genes governing days to maturity to chromosomes 3A, 5A, 6A, 38, 2D, 5D and 7D. Of these, genes present on 6A and 7D chromosomes were responsible for late maturity while those on others for early maturity. For culm thickness, chromosomes 4A, 58, 68, 3D and 5D were found to be significant where genes on all these chromosomes have negative effect on culm thickness.
