在春播和夏播两种环境条件下,对220个BC2S1普×爆家系的膨爆特性及其与穗粒性状进行了相关分析,结果表明:除爆花率外,其余膨爆性状均分离出较多优于爆裂亲本的家系;膨爆特性间呈极显著正相关,膨爆特性与穗粒性状间多呈极显著或不显著负相关;膨化体积对膨化倍数的直接正向作用最大,百粒重的直接负向作用最大,爆花率通过膨化体积对膨化倍数的间接作用为最大正效应,穗粒重通过百粒重对膨化倍数的间接作用为最大负效应。
Under spring and summer sowing conditions, the popping characteristics of 220 BC2S1 Popcorn families and their correlations with grain traits were analyzed. The results showed that except the popcorn rate, the other popcorn characters were all separated More than the popularized parent family; the popping and explosion characteristics were highly significant positive correlation, the popping and poplar characteristics were mostly significant or not significant negative correlation; puffing volume of puffing multiples of the largest direct positive effect, Hundred The direct negative effect of grain weight is the largest. The popularization rate is the maximum positive effect through the indirect effect of puffing volume on the puffing multiple. The indirect effect of grain weight on puffing multiple is the biggest negative effect.
