Output can be improved by reducing the plant height, improving available spikelet and seed setting rate and combining kernel number per spike with thousand kernel weight.
适当降低株高、增加有效小穗数、提高结实率、穗粒数与千粒质量并重、主攻穗粒质量是提高小麦产量的有效途径。
Correlation analysis of characters indicates that shortening heading date can cause the increase in grains number per spike and 1000-grain weight, but decreases in spikelet per spike.
性状相关分析表明，随着抽穗期缩短，穗粒数和千粒重增加，但小穗数有减少的趋势。
Under different water regimes, spike number per plant (SNP), effective spikelet per spike (ESPS) and peduncle length (PLE) contribute a lot to the stable grain yield.
不同水分条件下，植株稳产性主要受单株穗数、有效小穗数及穗下节长的影响；
