Under the climatic conditions of Chengtu, art early variety of soybean, Pai-shuitou, is usually sown in early March and harvesed in late June. The seeds thus harvested will deteriorate during summer storage and cannot be used for propagation next spring. In order to maintain the seed viability, such soybean has to be sown once more immediately after harvest so as to yield fresh seeds in autumn for propagation next year. The yield of the second crop, however, is poor and the practice requires land and labour. The present investigation has shown that the seed deterioration in this variety of soybean is mainly due to the high temperature in the summer of Chengtu. If the soybean should be kept at a low temperature throughout the summer, the seed viability would be safely maintained to approach that of the second crop.
