以沈农265等33个辽宁省主栽品种及区域试验品种(品系)为试材,研究穗部性状与茎叶性状关系的结果表明,单株有效穗数与多数穗部性状呈极显著负相关,而每穗粒数与多数穗部性状呈极显著正相关,剑叶长与单株有效穗数呈显著负相关,剑叶和倒2叶鞘长与一次枝梗数、一次枝梗饱粒数、着粒密度呈极显著负相关,倒1节间与一次枝梗数、一次枝梗饱粒数、着粒密度呈显著负相关,倒3节间长与单株有效穗数呈显著正相关. The main cultivars and regional test varieties (strains) of 33 Liaoning Provinces such as Shennong 265 were used as materials to study the relationship between panicle traits and ear traits. The results showed that the number of panicle per panicle and most panicle traits were significantly negative While the number of spikes per panicle was significantly and positively correlated with most panicle traits. The length of flag leaf was significantly negatively correlated with the number of panicles per plant, , Grain density was significantly negative correlation, down 1 internode and primary branch number, primary branch grain number, grain density was significantly negative correlation, down 3 internode length and the number of effective panicles was significantly positive correlation.
