豆科作物蛋白质是赖氨酸、精氨酸和亮氨酸之源,但其中多数含蛋氨酸、胱氨酸和色氨酸较低,因而向改进蛋白质的氨基酸组成选育豆科作物时,首先要注意到这些氨基酸。1973—1981年在波尔塔瓦农业试验站,用苜蓿、红豆草和三叶草进行试验,利用试验站育种处的不同苗圃的育种材料,于开花 Legume crop proteins are sources of lysine, arginine and leucine, but most of them contain methionine, cystine and tryptophan, and therefore, to improve the amino acid composition of the protein to breed leguminous crops first Be aware of these amino acids. 1973-1981 At the Poltava Agricultural Experiment Station, trials were conducted with alfalfa, sainfoin and clover, using breeding material from different nurseries at the breeding site of the test station,
