Abstract

Abstract: Yield and main economic characters of ten main cropping and ratoon cropping rice variteies in Xinyang city were comprehensively studied by the method of grey relational analysis. The results showed that the most suitable rice variety in Xinyang was Fuliangyou 1 mainly in the equal relational grade analysis and the weighted grade analysis, followed by Liangyou 6326 and Wandao 199. The degree of association of three varieties were close to the target, such as fengyuanyou 358, Suiyuan 9 and Liangyou 302. Wanhanyou 26 was not suitable for ratoon rice cultivation in southern Henan region.

Key words: ratoon rice, variety selection, grey relational analysis

摘要： 为筛选出适合豫南稻区种植的再生稻品种，本试验应用灰色关联度分析法，对10个再生稻品种头季及再生季的产量和主要经济性状进行关联分析。结果表明，富两优1号的等权关联度和加权关联度均最大，是豫南稻区理想的再生稻品种；其次是两优6326和皖稻199；丰源优358、穗源9号、两优302等3个品种与目标品种的关联度接近，也可作为再生稻在豫南稻区种植；皖旱优26的关联度较小，与目标品种相差甚远，不适合在豫南稻区作再生稻种植。
