GENE EFFECTS IN FOUR METRIC TRAITS OF RICE BEAN

Published on

Scaling tests and analysis of genic and interaction components of four metric traits were carried
out in the progeny of three crosses involving four strains of rice hean (l'igus
umbe/hlla Thunb).
Ohwi
& Ohashi). Scaling tests A and C were significant for days to flower and greeh forage yield
. in two crosses. Additive gene effects were predominant for days to flower and plant height, whereas
dominance effects were of ml\ior importance for nunther of branches per plant and green forage
yield. Duplicate type genic interaction was noted for green forage yield.
It is suggested that the
significant dominance and interaction components can he exploited through the development of
composite varieties in rice bean utilizing its very high rate of natural outcrossing.
