近年来,我国许多作物育种单位利用海南岛进行冬季继代试验,对加快新品种的选育和推广,起到了一定作用。要更有效地进行南育,就需要了解作物植株各主要性状在南北两地的表现和变化规律,以便进行正确的选择与培育。本文根据1976—1978两个年度在南北异地种植的不同类型大豆品种的观察研究结果,对这个问题加以讨论。 In recent years, many crop breeding units in China make use of Hainan Island for the winter subculture test, which plays a certain role in accelerating the breeding and popularization of new varieties. In order to carry out southern education more effectively, it is necessary to understand the behavior and variation of major traits of crop plants in both North and South in order to make the right choice and cultivation. This article will discuss this issue based on the observations of different types of soybean cultivars grown in different places in the north and south in 1976-1978.
