ABSTRACT

Combining ability studies for grain traits revealed additive' gene action for plant height,
number of grain rows per cob, number of grains per row, cob weight,days to 50 % silk and
hundred gram weight. Based on the Per se performance and effects UMI 760, Prabhat-1 and
JM 3181-1 were found to be the best parents for improvement of grain traits besides grain
yield. Prabhat-1 x UMI492, UMI 760 x JM 3181-1 and UMI 805 x UMI 76Q are suitable for
recombination breeding
