There is a difference among genotype in ratio of ARS to WRS.有效吸收面积ARS与根系总表面积WRS的 比值具有品种间的差异.The genotype of the individual is permanently set.个体的基因型就永久地被固定下来.In truly doubtful cases, only test crosses will reveal the act...
In truly doubtful cases, only test crosses will reveal the actual genotype.在确实可疑的情况下, 只有通过杂交试验才能揭示出真正的基因型.Therefore, P should be substituted by a response surface for each genotype.因此, P必须被各个基因型的反应面所代替.The genotype of th...
