Studies on the f2 generation of inter-varietal crosses in rice

Abstract

In the study of the Fa generation of the cross of two improved dryland strains and a locai medicinal variety of rice with two high yielding varieties revealed that all the characters under observation were inherited polygenically. F2 segregants surpassing the higher parental limit in their mean yield were obtained. No significant correlation was observed between yield and plant height, number of tillers, panicle length and 1000 grain weight.
