摘　　要：高粱品种对养分胁迫的耐瘠性是由株高基因和熟性基因控制的。大部分单隐性株高基因控制的品种比 2个或 3个隐性株高基因控制的品种耐瘠性差 ,自我调节能力不佳 ,最终不能形成产量。熟性基因 1位点为隐性基因ma控制的品种 ,适应性强 ,生育期短 ,耐瘠水平高 ;而 1位点是显性基因Ma控制的品种 ,适应性差 ,生育期长 ,耐瘠力不高。The tolerance of sorghum varieties to malnutrition stress was associated with the genes of plant height and maturity. The tolerance of sorghum varieties with single recessive gene on plant height was lower than that of the varieties with two or three recessive plant height genes. The sorghum varieties with single recessive gene on plant height had low self-regulating ability, and could not give yield. The varieties with recessive gene (ma) at location one had stronger adaptability, shorter growing period, and higher tolerance ability to malnutrition stress than the varieties with dominant gene (Ma).
