利用１１个新选育、原产不同地理纬度的南方春大豆晚熟品种，经过７个试点的春播试验，以各品种的生育期特性在各试点间的变异方差为指标，研究这些新品种对光温综合反应的敏感程度。结果揭示，原产低纬度地区的品种，全生育期光温综合反应特性远较原产纬度偏高地区的品种迟钝。在供试品种中，滇８６—４、蒲豆８００８和桂早一号的全生育期的光温综合反应最为迟钝，滇８６—５和贡豆９４—３较为敏感；出苗～开花时期的光温综合反应以黔９２—２６和成８６０１较为迟钝，以贡豆９４—３和桂早一号等较为敏感；开花～成熟的光温综合反应，以滇８６—４最为迟钝，贡豆９４—３最为敏感。
Using 11 newly-bred South China spring soybean late-maturing cultivars with different geographical latitudes, after seven pilot spring sowing trials, the variation variances of the growth period characteristics of the cultivars in each experimental plot were used as indexes to study the effects of these new cultivars on light Temperature Comprehensive response sensitivity. The results revealed that the comprehensive response characteristics of light and temperature during the whole growth period of native low-latitude regions were far more dull than the native latitudes. Among the tested cultivars, the light and temperature of the whole growing period of Yunnan 86-4, Puao 8008 and Gui Zui No.1 were the most retarded, while that of Yunnan 86-5 and Gongding 94-3 was the most sensitive. The light of emergence-flowering The results showed that the comprehensive response to temperature was more sensitive to Qian 92-26 and Cheng 8601, more sensitive to Gongding 94-3 and Gui Zao 1, and the combination of flowering and maturity in light and temperature, 3 is the most sensitive.
