摘要： 本研究是结合育种实践,连续进行了五年的试验。主要是探讨水稻不同生态型亲本组合以及不同生态型的双亲生育期差异对 F1和 F2抽穗期的影响。试验结果,F1抽穗期表现为:双亲生态型差异大的,F1超早超晚均突出,双亲生态型相近的,F1倾早倾晚机率相差不大。而 F1

Abstract: Observations on genetic variability of dates of heading of F1and F2 generations of 384 single crosses among various ecologicaltypes in rice were made during the period of 1975-1978.The resultswere summarized as follows1.The first generation hybrids between different ecological
