New genotypes with multiple pistils and inheritance pattern of this trait in rice

Abstract

Present study investigated genetic basis of multiple pistil. The experimental material consisted of Ram Laxman and Dodana indigenous varieties with distinguishable multiple pistil trait were used as male parents, while R710-4-37-1-1-1-1 with single grain trait were used as female parents. Two segregating F2 populations for target trait were developed. The segregating ratio revealed that multiple pistils trait was governed by single recessive gene in the varieties Ramlaxaman and Dodana and it is revealed that normally only one grain is set in each of the spikelet.
