Progress and Problem Analysis on Soybean Male Sterility and Heterosis Exploitation in China
Heterosis exploitation is one of efficient measures to increase soybean yield. In the period of the mid of 1980s, studies on soybean heterosis exploitation were conducted by several research institutions in China. Through exploring with more than 20 years,on the whole,China has been ranked the first position in the field of soybean heterosis exploitation. The "three lines"with cytoplasmic male sterility and several hybrid cultivars were first developed by Chinese scientists. The heterosis tests of soybean on a large scale and the seed reproduction techniques of hybrid soybean were also studied in China. However,the course of industrialization of hybrid soybean is still slow in China. There are a series of problems to be resolved in the production of hybrid soybean. The progress on studies of soybean male sterility and heterosis exploitation in China was summarized and some suggestions were put forward by the authors in this article.
