在春播和夏播两种环境条件下,对普通玉米自交系与爆裂玉米自交系杂交组配的259个F3家系的膨爆特性及其与穗粒性状的相关分析结果表明:F3家系膨爆特性较差,采用常规系谱法从中选育出优良爆裂玉米自交系的几率较小;膨爆特性都是由多基因控制的数量性状;膨爆特性间呈极显著正相关,膨爆特性与穗粒性状间多呈显著或极显著负相关;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 the spring and summer sowing conditions, the popping and blasting characteristics of 259 F3 families crossed with normal maize inbred lines and popcorn inbred lines and the correlation analysis with grain-ear traits showed that: The blast characteristics were poor, and the probability of breeding excellent inbred maize lines with conventional genealogy method was small. The popping properties were all quantitative characters controlled by multiple genes. The characteristics of swelling and explosion were extremely significant positive correlation and the swelling and explosion characteristics There was a significant or very significant negative correlation between the puffing volume and puffing grain traits. The puffing volume had the largest positive direct effect on the puffing fold, the direct negative effect of the hundred puffs was the largest, and the popciation rate was the largest Positive effect, grain weight through the hundred weight on the puffing multiples of the indirect effect of maximum negative effect.
