Inheritance of Female Sterility in Sorghum

Inheritance of female sterility was studied by crossing seven male sterile lines and thirteen indigenous and exotic varieties with E. Kalo. The present findings confirmed that female sterility is governed by complementary genes Fs₁ and Fs₂, In Pratapgarh, Spur Feterita, Bichpuri, I.S. 1150 and Jowar 4692 B only rescessive alleles at these complementary loci are present. While Early Kalo has one gene (Fs₁ in homozygous dominant condition, others have the second gene (Fs₂) in homozygous dominant condition.
