Grasspea is a neglected legume but has the potential to become an important crop in dry regions. Grasspea lines L880283 and L900436 were reciprocally crossed and the progenies were evaluated for expression of male fertility/sterility. When line L900436 was used as the male parent, F1 progenies were sterile, but F1 progenies of the reciprocal cross were all fertile. Fertile and sterile F1 progenies were back-crossed with parental lines, and two other breeding lines, and the progenies were evaluated for male fertility/sterility under field conditions. Back-cross progenies (BC1) with sterile F1 progenies segregated into combinations which indicated that both cytoplasmic and genetic systems of male sterility may be operating along with environmental influence in the control of expression of male sterility
