蓖麻杂交新品种丰产性及稳定性试验初报

The Preliminary Report of Yielding Ability and Stability Test of Castor New Hybrids

鉴定杂交蓖麻新品种的稳定丰产量能力,为生产上推广应用提供依据。以"淄蓖麻2号"为对照,在山东省不同生态区进行了一年多点的品种比较试验,通过对一年五地试验结果的统计分析,求得衡量品种丰产性和稳定性的参数,并据此对参试品种进行丰产性和稳定性分析。淄蓖麻7号、5号、6号和淄蓖麻2号平均产量分别为4908.74、4775.70、4625.92和3258.37kg/hm^2;品种和环境互作效应值分别为2.3245、1.7258、1.0518和-5.1022;变异度分别为0.7240、1.0629、-0.7041和2.5102。"淄蓖麻7号"和"淄蓖麻5号"表现出了极好的丰产性和稳定性,有广泛的适应性。"淄蓖麻6号"也具有较好的丰产性和稳定性,在条件适宜的地区进行合理种植,也能获得稳产高产。

In order to evaluate the yielding ability and stability of the new hybrid castor varieties and provided support for expanded,Controlled experiments with Zibo castor No.2 in different ecology areas of Shandong province had been down more than a year.By analyzing the statistical results of five areas obtained the parameter for yielding ability and stability,and according the parameter the yielding ability and stability of the test varieties of hybrid castor had been analyzed.The results of text showed that the average yields of Zibo castor No.7,No.5,No.6 and No.2 was 4908.74 kg/hm2,4775.70 kg/hm2,4625.92 kg/hm2 and 3258.37kg/hm2; the G×E interaction effect was 2.3245,1.7258,1.051 and-5.1022;the variability was 0.7240, 1.0629,-0.7041 and 2.5102.＂Zibo castor No.7＂and＂Zibo castor No.5＂had excellent yielding ability and stability in a wide range of conditions.＂Zibo castor No.6＂also had good yielding ability and stability in suitable conditions.
