本研究以黑龙江省近百年不同时期推广的59个代表品种为材料,所调查的10个数量性状应用对应分析,按品种与性状的聚合自然趋势,将全部性状和品种划分为Ⅳ区,并作图和成因解释,找出了相应性状突出的品种。从对应分析结果表明,影响产量的特征系数为单株粒数和千粒重,同时受两个主因子轴的控制。
In this study, 59 representative cultivars popularized in different times in Heilongjiang Province in the recent 100 years were used as materials. The 10 quantitative traits investigated were applied to the corresponding analysis. According to the natural tendency of the aggregation of cultivars and traits, all the traits and cultivars were divided into four areas Figure and genesis explained to identify the corresponding traits prominent varieties. From the corresponding analysis results show that the characteristic coefficients affecting the yield of grain per plant and 1000-grain weight, at the same time by the two main axes of control.
