摘要
花９４０小麦用花药培养而成，在品系鉴定、品比试验、河北省区域试验和生产试验的６年试验中，连续５年平均产量排第一位，１年排第二位，历年平均产量比对照增产１２．１％。花９４０小麦苗期次生根比对照多３５．０％，灌浆期次生根比对照多２０．５％，最高蘖比对照提高１５．２％，每穗粒数比对照多３，４个且叶层分布合理。
The new wheat variety, H-940 was cultivated throught another method H-940 rankedfirst in 5 years preliminary yield comparison and provincial trails. and ranked second in oneyear with an average yield increse by 12.1%。The resons were as follow :The secondaryroot number of H-940 were 35.0% and 20.5%more thn that of control at seedling andgrain filling stage,respectively,The maximum tiller was increased by 15.2%,and the grainnumber per spike was 3. 4 more than that of control.The idea leaf configuration also con-tributed to the high yielding of H-940.
