区域试验的参试品种代表了当前育种的基本水平。研究这些品种在各地的生态反应,对确定育种目标与选择手段可以提供借鉴。1977年区域试验逐步恢复以来,截至1979年,长江流域棉花品种区试、江苏省麦套棉花品种区试与麦后棉花品种区试的参试品种为17个,试验点次为78个,其中分布于盐城地区境内的点次为13个。本文试图应用区域试验等资料就我区棉花早熟育种问题,进行一些分析与探讨。
The tested varieties in the regional trials represent the basic level of current breeding. Studying the ecological responses of these varieties in various places can provide reference for determining breeding objectives and selection methods. Since the gradual restoration of regional trials in 1977, as of 1979, there were 17 varieties tested in the Regional Trial of Cotton Varieties in the Yangtze River Basin, the Regional Trial of Wheat Variety and the Cotton Variety Area of Wheat Variety in Jiangsu Province. The number of test points was 78, of which Distributed in the Yancheng area of the point of 13 times. This article attempts to apply regional trials and other data on cotton preculture in our area, some analysis and discussion.
