摘    要:对湖北省随州市曾都区种植的杂交中稻培两优3076产量性状的相关性及其通径分析结果表明,每公顷穴数和穗数与实际产量之间呈极显著正相关,相关系数分别为0.7820和0.7406;每公顷穴数与每公顷有效穗数、每穗实粒数与每穗颖花数和每穗实粒数与结实率间呈极显著正相关,而每公顷穴数与每穴有效穗数、每穴有效穗数与每穗实粒数和每穴有效穗数与每穗颖花数间呈极显著负相关.在制定相应的水稻高产栽培措施时,应在早期适当增加每公顷穴数,在中、后期主攻大穗,提高结实率,协调好每公顷穴数、每穗颖花数和结实率之间的关系.

关 键 词:杂交中稻  培两优3076  产量性状  相关性  通径分析

Abstract:Correlation and path analysis on the yield traits of Peiliangyou 3076 grown in Zengdou county,Suizhou city,Hubei were analysed.The results indicated that there were obvious positive correlation between the hole number per ha.and actual grain yield,the spike number per ha.and actual grain yield.The correlation coefficients were 0.7820 and 0.7406 respectively;There were obvious positive correlation between the hole number per ha.and the spike number per ha.,the filled grain number and the glume number per spi...
Keywords:hybrid medium rice  Peiliangyou 3076  yield traits  correlation  path analysis
