Abstract
Linkage among major genes can markedly affect incorporation of desirable characteristics into improved varieties. Crosses among four rice (Oryza sativa L.) breeding lines were investigated in F2 and F3 generations to determine linkage relationships among the semidwarfing genes sd1, sd2 and a gene conditioning glabrous leaves and hulls, gl, in rice. F3 information was used to classify F2 plants, with analysis being based on F2 populations. The three genes were found to assort independently.
