从小麦主要性状与气候因素的相关分析,探讨克字号小麦新品种选育方向

根据小麦所常规室小麦产量试验7年的数据，研究了同一品种不同年份各性状间的相关性，以及主要性状与气候条件的关系。结果表明，小麦主要性状与气候因素密切相关。其中气温、降水对籽粒产量的影响比较突出。不同生态类型品种产量要素与产量间的相关差异较大，根据不同生态类型试验品种的特征特性探讨克字号高产、优质、多抗、适应性广的小麦新品种的选育方向，即西部应在保持新克旱九号小麦千粒重的基础上，增加株粒数；东部则应在保持克丰三号小麦林粒数的基础上，增加千粒重。

Investigating Selective Breeding Direction of the Keshan Wheat's New Varities by Correlative Analysis of Wheat's Major Characters and Climatic Factors

According to the seven's daturn of wheat yield trials. author studied correlationamong character and relationship between main characters and climatic factors with samevarlety and different years. The results showed that the main characters of wheat was closecorrelation with climatic factors, which the temperature and precitation have a more re-rnarkable effect to the grain yield. The correlatlon is great difference between the main yieldfactors and yleld in the different ecotype's test varieties, author investigated selectivebreeding directlon of the Keshan wheat new varieties whiuch have high yield, good quality,much resistance and wide adaptive faculty. In the west region, it must add the grain quantityof a plant that is based on maintalning the thousand kernal weight of the No. new Kehan9. Inthe east region. it must add the thousand kernal weight that is based on maintaining thegrain quantity of a plant of No. Kefeng3.
