沙地衬膜水稻新品种丰产性与稳产性及适应性研究

Study on Fertility and Adaptability of New Rice Variety with Sandy Soil

为了科学地评价和鉴定沙地衬膜水稻品种丰产性、稳定性、适应性等综合利用价值,在通辽地区进行了4个点、6个品种的筛选试验。结果表明,经品种丰产性回归分析,吉特639品种在各地点产量列为第1位,其次为稻花香2号,再次为吉粳88。AMMI法品种稳定性分析结果表明,稳定性好的品种排序为吉粳88>一见丰优>绿香稻>吉特639>丰优307>稻花香2号。品种适应性分析结果表明,吉特639、吉粳88和稻花香2号3个品种表现较佳。综合比较认为,吉特639表现最优,产量高达7 748.25 kg/hm^2,品种稳定性较好,适应性强。

Screening test of four points, six varieties were studied, in order to identify and evaluate fertility and adaptability of new rice variety with sandy soil.The results showed that Jite 639＇s yield rank first in all points ,followed by Daohuaxiang 2 ,Jigeng 88. The order of stable varieties is Jigeng 88〉Yijianfengyou〉Lvxiangdao〉Jite 639〉Fengyou 307〉Daohuaxiang 2 by AMMI method. The adaptability of 3 varieties （Jite 639, Jigeng 88, Daohuaxiang 2）is better. On the whole ,Jite 639 achieved the best performance ,the yield is as high as 7 748.25 kg/hm2,the variety stability is good,and the adaptability is strong.
