摘要
利用AMMI模型对2009年贵州省粳稻区域试验结果进行品种稳定性和适应性分析。结果表明:2条显著的IPCA1I、PCA2主成分轴共解释了84.5%的互作平方和,品种毕08-1、YR709产量高但稳定性较差;云光109、滇杂31、毕粳杂2035产量较高且稳定性好;早丰九号稳产性好但产量较低;W025产量低而不稳。高产类型品种中毕粳杂2035除晴隆外,具有广泛的适应性;毕08-1、滇杂31、云光109、云光101对毕节、晴隆、都匀具有特殊适应性,YR709对晴隆、贵阳、都匀具有特殊适应性。
The stability and adaptability of rice varieties in Guizhou regional test of japonica rice was analyzed by AMMI mode.The results showed that 84.5% interaction sum of squares could be explained by two significant IPCA1 and IPCA2.The stability of Bi08-1 and YR709 varieties with high yield is poor.The stability of Yunguang109,Dianza31 and Bijingza2035 with high yield is good.The yield of Zaofeng 9 with good stability is low and the stability of W025 is poor.Yunguang109,Dianza31 and Bijingza2035 varieties with high yield are of wide adaptability except for Bijingza2035 in Qinglong.Bi08-1,Dianza31,Yunguang109 and Yunguang101 varieties are of special adaptability in Bijie,Qinglong and Duyun.YR709 variety is of special adaptability in Qinglong,Guiyang and Duyun.
