研究表明：穗长与各爆裂性指标呈显著正相关，对ＶＡ／ｇ的直接作用最大，通过其它各性状的间接作用均较小；百粒重虽与ＶＡ／粒呈极显著正相关，但与ＶＡ／ｇ的负相关系数较大，且对ＶＡ／ｇ的直接作用为最大负值；行粒数虽与各爆裂性指标的相关不显著，但对ＶＡ／ｇ的直接作用为较大负值；穗行数与ＶＡ／粒呈显著负相关，但对ＶＡ／ｇ的直接作用及通过其它性状的间接作用均较小；穗粒重与ＶＡ／粒呈显著正相关，对ＶＡ／ｇ的直接作用为较小正值，通过穗长的间接作用为较大正值。育种中要同时兼顾产量和爆裂性，可直接选择穗粒重，或在适当兼顾穗行数的前提下选择穗长或行粒数，对百粒重则不宜进行正向选择。
The results showed that there was a significant positive correlation between the spike length and each burst index, the direct effect on VA / g and the indirect effect through other characters were small. The 100-grain weight had a significant positive correlation with VA / grain The negative correlation coefficient with VA / g is larger and the direct effect to VA / g is the maximum negative value. Although the correlation between row grain number and each burst index is not significant, the direct effect on VA / g is larger negative Value; the number of ear rows was negatively correlated with VA / grain, but the direct effect on VA / g and the indirect effect through other traits were small; grain weight per spike was positively correlated with VA / grain; Direct effect of smaller positive values, through indirect effects of spike length for larger positive values. Breeding to both yield and burst, you can directly select the grain weight per spike, or take into account the appropriate number of rows under the premise of spike length or row grain number, the weight of 100 is not the right choice.
