摘要
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。
11 newly developed late spring soybean lines originated from various latitude in south China were included to test their reaction sensitivity to photothermal in 7 locations, with the variance of growth stage among locations as criteria. This group of soybean lines revealed an inverse photothermal reaction tendency as compared with local. native varieties as for full growth period. Such conclusion was thought to be the result of more severe stress on the selection of growth period reaction sensitivity to photoperiod and temperature so as to release varieties with highly improved adaptation. Dian 86-4, Pudou 8008 and Guizao No.1 were the most photoperiodtemperature insensitive varieties, while Dian 86-5 and Gongdou 94-3 were the most sensitive as for full growth period. Qian 92-29 and Cheng 8601 were most insensitive as for the period from emergence to flowering, and Dian 86-4 most insesitive as for the period from flowering to maturity.
