- The effect of removing base spikelet on setting kernels and grain weight was slighter, kernels and grain weight per ear decreased less. 去除基部小穗对结实粒数和粒重的影响较小穗粒数和粒重下降较少；
- GCA effect on kernel weight per ear of LBM and WLS was higher, and GCA effect of BS16(CB)C4 was lower. BS16（CB）C4的单穗粒重GCA最低，LBM、WLS的GCA较高。

- Water stress during anthesis and kernel stage effects most greatly the thousand-grain weight and the grain number per ear,yield decreases more greatly. 花粒期阶段水分胁迫对千粒重及穗粒数影响最大，产量降幅更大。
- The seed number and weight per ear increased by 24.2% and 26.77%,respectively. 单穗粒数和粒重分别比对照增加24.;2%25和26
- Narrow heritabilities of rows per ear and plant height are higer than 50%. 穗行数和株高的狭义遗传力超过了50%25
- In conclusion, more spikelets and kernels per spike were the most valuable traits in turgidum landraces, and could be utilized in wheat breeding. 本研究认为，多小穗数和多穗粒数是圆锥小麦地方品种最突出的优良性状，可做为小麦育种的重要基因资源。
- The heterosis mainly showed higher kernels per head, the application of Multi-ovary wheat should strengthen the improving of other agronomic characteristics. 多子房小麦杂种优势的主要表现是穗粒数增多，其生产应用还应注意加强对多子房小麦其它农艺性状的改良。
- The higher plant height, more spikelets and kernels per spike, lower 1000-grain weight and longer growing time were found to be the main characters of those landrace. 在株高、分蘖数、有效穗数、穗长、小穗数和穗粒数等性状上供试材料间存在极显著差异。
