Abstract

MonosQmic lines of Kalyansona were crossed with OWR-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, SA,
6A, 38, 20, 50 and 70. Of these, genes present on 6A and 70 chromosomes were responsible
for late maturity while those on others for early maturity. For culm thickness, chromosomes
4A, 58, 68, 30 and 50 were found to be significant where genes on all these chromosomes
have negative effect on culm thickness.
