小麦冬春性人工低温春化鉴定的研究
Research on Identification of Winterness and Springness of Wheat Varieties through the Artificial Vernalization Method
摘要
Abstract
To screen out the identification methods and indicators for winterness and springness of wheat indoor,we used Jimai 19,Qianjiaomai,Taishan No.1,Jimai 20 and Chinese Spring as the control of strong winterness,winterness,semi-winterness,partial springness and springness wheat,respectively,and 108 wheat varieties from Shandong Regional Test during 2014-2016 were selected to identify the winterness and springness through indoor identification,intermission spring seeding in field,and molecular identification.Through the observation of seedling habits,heading rate and heading period,we confirmed the reliability indicators for identifying winterness and springness of wheat indoor,proposed the indoor identification method of winterness and springness of wheat varieties,and preliminary established the identification system using the artificial vernalization method to determine the winterness and springness of wheat indoor.The indentification system was as follows:under the condition of 2℃,the time for springness,partial springness,semi-winterness,winterness,strong winterness wheat varieties to complete vernalization were 0 d,0 d ＜ t≤20 d,20 d ＜t≤30 d,30 d ＜t≤40 d and t＞40 d,respectively.关键词
