本文对来自全国各大麦区的供试品种,进行了春化反应与田间周年播种反应的研究。用系统聚类法将40个供试品种分为两个大集团、三个分枝、六个较明显的类型。这六个类型是强春型(SS)、春型(S)、冬春型(WS)、冬型(W)、强冬型(SW)和超强冬型(USW)。六个类型进一步划分,又可分为九个系列等级,每个系列等级都包含若干顺序排列的品种,看出品种对低温春化反应是一种连续的数量效应累加过程,具有连续的依次排列性。试验发现供试品种的春化效应跨度由辽春6号的零反应型到肥麦的70天以上的超春化反应型,大大超过我国五十年代春化研究的反应幅度。说明我国育种与品种资源利用幅度的广泛性。
In this paper, we studied the vernalization reaction and annual sowing reaction of tested varieties from all the major barley regions in China. By cluster analysis, 40 cultivars were divided into two large groups, three branches and six more obvious types. The six types are Strong Spring, Spring, WS, Winter, SW and USW. The six types are further divided and divided into nine series, with each series containing a number of sequenced varieties. It is seen that the varieties are a continuous accumulation of quantitative effects on low temperature vernalization and are successively arranged Sex. The results showed that the vernalization effect of tested varieties ranged from zero-reaction type in Liaocheng 6 to over 70-day super-vernalization reaction in fertilizer and wheat, which greatly exceeded the response of the vernalization study in China in the 1950s. Explain the wide range of utilization of breeding and variety resources in our country.
