研究水稻穿梭育种世代材料在不同生态稻区的表现,结果表明,生育期的长短随纬度的升高而延长,植株高度随日平均气温的升高而增高.不同生态稻区表现的农艺性状的变异系数呈相似的趋势,上下代农艺性状有一定相关性并明确了不同生态稻区选种类型。
The results showed that the length of the growing period increased with the increase of latitude and the height of the plant increased with the increase of the daily average temperature.The agronomic characters of different ecological rice areas The coefficient of variation showed a similar trend. The agronomic traits of the upper and lower generations had some correlations and the types of selected varieties in different ecological rice areas were clarified.
