昆明、威宁小麦夏繁效果的比较研究

Comparison on Summer Reproduction of Wheat in Kunming and Weining

采用从春性到冬性的21份材料在云南昆明和贵州威宁进行夏繁试验,结果表明,两地气候条件在满足小麦低温春化阶段上有一定差异,但均能够满足本区选育半冬性早熟类型品种要求,在经济性状上威宁显著优于昆明,但生育期却较昆明长。

21 wheat varieties, springness or winterness, have been tested for its reproduction characteristics in summer in Kunming and Weining. The results show that there are some differences to meet the vernalization requirements in two places, but the requirements for breeding earlyripen and semiwinterness varieties can be satisfied in both places. The economic characteristics are better but the growth period is longer in Weining than those in Kunming.
