河南省中肥小麦新品种稳产性分析和品种评价

Yield Stability Analysis on Medium-Yielding Wheat Cultivars Grown in Henan Province

采用联合方差和回归分析方法对河南省5个中肥小麦品种8个试点的产量资料进行了分析,结果表明,豫麦十二号宜在亩产300公斤以上的环境条件下种植,而郑州853则宜在300公斤以下的产量水平环境条件下能够发挥较大的增产潜力。与其它参试品种相比,博农7023产量较低,故不宜再推广种植。本文还结合其它性状的考查,综合评阶了各品种的利用价值。

Results of 5 medium-yielding wheat cultivars analysed show that the cuHi- var of Yamai 12 is saitable to grow under the environment with yielding level of 300 kilogram per mu or above,but ehat below 300 kilo gram,Zhengzhou 853 can have higher yield potentiaii.Bonong 7023 yields low in all locations.The utilization value for all cultivars used in this experiment has been comprehens- ively evaluated.
