对36个优良玉米自交系组配的300个杂交种的酯酶同工酶酶谱分析发现:互补酶带、杂种酶带的出现与否,不能准确预测杂种产量的高低;双亲酯酶同工酶的差异在一定程度上能反映杂种优势的大小。
The analysis of esterase isozymes in 300 hybrids of 36 elite maize inbred lines showed that the presence of complementary bands and hybrid bands could not accurately predict the yield of hybrids. The differences in enzyme can reflect the degree of heterosis to a certain extent.
