Abstract:
Grain amaranth (Amaranthus spp.) has been cultivated since ancient times in some countries in the world which is one of the ancient food crops. Studies of intra specific and inter specific outcrossing rates were carried out for grain amaranths using populations of A. hypochondriacus, A. caudatus and A. cruentus. Studies of outcrossing were carried out using different species at Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat, India, which resulted that the highest outcrossing rate was observed in Annapurna (A. cruentus) (25–35%) followed by IC–381135 (A. caudatus) (11–20%) and the lowest in GA-1 (A. hypochondriacus) (4–11%), while no outcrossing rate was observed in GA-2 (A. hypochondriacus). The outcrossing rate showed substantial variation between and among the species. Significant variations in the outcrossing rates might be due to variation in location and season.
