辣椒产量与相关农艺性状的灰色关联度分析

采用随机区组试验设计,利用灰色关联度分析法对18个辣椒杂交组合产量与其主要相关农艺性状,进行了灰色关联度分析。结果表明:(1)辣椒杂交组合单株产量与其主要相关性状的关联度大小依次为:青椒产量〉平均单果重〉果径〉红椒产量〉株高〉坐果率〉红椒数〉始花节位〉果长〉果形指数〉青椒数〉总果数;(2)青椒产量与其主要农艺性状的关联度大小依次为:单株产量〉株高〉平均单果重〉始花节位〉坐果率〉果径〉红椒产量〉果形指数〉果长〉总果数〉青椒数〉红椒数。因此,在辣椒杂交育种过程中可以把平均单果重、果径、株高和始花节位作为选育的重点性状,并结合其他性状进行综合筛选。...

Using randomized block experimental design, the correlations between the yield and related agronomic characters of 18 pepper hybrid combinations were analyzed with the method of grey correlative degree analysis. The results showed that the values of the grey correlative degree between the single - plant yield and main agronomic characters of different varieties were sequenced as follows : green pepper yield 〉 mean fruit weight 〉 fruit width 〉 red pepper yield 〉 plant height 〉 fruit set percentage 〉 the number of red pepper 〉 first flower node 〉 fruit length 〉 fruit shape index 〉 the number of green pepper 〉 total fruits. The values of the grey correlative degree between the green pepper yield and main agronomic characters of different varieties were sequenced as fol- lows : single -
