摘要
对11个2009-2010年度全国早熟组油菜区试新品种的小区产量及相关农艺性状进行灰关联熵分析。结果表明,各农艺性状与小区产量的熵关联度为:株高0.9867,一次有效分枝数0.9871,主花序长度0.9889,主花序角数0.9946,主花序结角密度0.9906,总角数0.9894,角粒数0.9847,千粒重0.9951,单株产量0.9982;熵关联序为:单株产量>千粒重>主花序角数>主花序结角密度>总角数>主花序长度>一次有效分枝数>株高>角粒数,可据此确定全国早熟组杂交油菜品种的选育方向。
Gray correlation entropy of yield and agronomic traits of 11 early maturing rape varieties from 2009 to 2010 were analyzed. The results showed that gray correlation entropy of agronomictraits and yield was that the height of plant, first branch number, main inflorescence length, siliques number, siliques density, total siliques, seeds per siiique, thousands seeds weight, yield per plant, were 0. 9867, 0. 9871, 0. 9889, 0. 9946, 0. 9906, 0. 9894, 0. 9847,0. 9951, 0. 9982, respectively. Correlation order were yield per plant〉 thousand seeds weight〉 siliques number〉 siliques density〉 total siliques〉 main inflorescence length〉first branch number〉plant height〉seeds per silique, its indicated that the gray correlation entropy is the main breeding object for early maturing rape in China.
