冀84-5418小麦品种稳定高产性能与适应性的初步分析

Preliminary Analysis on Stable-High-Yield Ability and Adaptability of Wheat Ji84-5418

利用冀84—5418连续四年参加各级区域试验及有关资料,分析其稳定高产性能与适应性。结果表明,该品种广泛适应于黄淮麦区,产量潜力大,在环境平均值340公斤/亩以上稳产性好,在品种单产374.5公斤以上超过其它品种。其丰产性、稳产性分别隶属于相互独立的基因系统,产量构成因素自身调节能力强,从而高产性与稳产性能够兼顾。同时表明运用Eberhart-Russell模式的两参数和其它统计数,评价单个品种多年、多点试验结果能够较全面、合理地反映品种真实情况。

The stable-high-yield ability and adaptability of wheat Ji34-5418 were analysed by using regional tests and their related data at different levels in four years. The results showed that the variety with a great yield potential was widely suitable for the Huang-Rai wheat area and stable in yield when the environmental average of yield was above 340 kg/ mu. Each of the abilities of high yield and stable yield was controlled by an independent-gene system. All the factors composing yield had self-regulation abilities to guarantee high and stable yields. The results also showed that using two parameters of the Eberhart-Russell model and other statistical data to evaluate multi-year and multi-site test results of a single variety could be a means to comprehensively and reasonably reflect the real state of the variety.
