Eight alfalfa synthetics were analysed for the components of grain yield in polycross. Average inflorescence length was 2.63 cm and there were 26.6 flowers per inflorescence. Except in synthetic of F1 generation on cms (cytoplasmic male sterility) basis, pollen fertility was high (71.8). The number of ovules per ovary was 9.7. The number of ripe pods per inflorescence was 8.2, with 2.92 seeds per pod and 1.98 g per 1000 seeds. Broad row alfalfa gave grain yield which ranged from 27.2 to 42.7 g per square m in 1991/93. According to stem height and grain yield stability, the synthetic 7 Syn 1, a new prospective variety with high genetic potential for fodder and grain yield, gave the best results.
