本文研究长江中游地区大豆地方品种资源的区域特点、产量及品质性状的选择潜势。与长江下游资源相比,中游资源具前期长、植株高、百粒重小、蛋白质含量高而油分含量低、多数性状变异较小的特点,小区产量与每英粒数及其它英性状显著正相关,而与生育前期、生育后期及百粒重无明显的关系。两地资源的产量与蛋白质含量、油分含量均无相关,蛋白质含量与油分含量均负相关。五个分区资源在产量、蛋白质含量及株型性状上存在差异,油分含量差异不明显。中游地区的小区产量GCV、h_B~2都较高,具有较大的选择潜力。油分含量、蛋白质含量的GCV低、h_B~2高,选择响应较大,但仍有必要创造变异。
This article studies the regional characteristics, yield and quality traits of soybean landraces in the middle reaches of the Yangtze River. Compared with the resources in the lower reaches of the Yangtze River, the resources of the middle reaches of the Yangtze River have the features of earlier prophase, high plant height, small weight of 100 grains, high protein content and low oil content, and less variability of most traits. Related, but with pre-fertility, late reproductive and 100 weight no significant relationship. There was no correlation between the yield of both resources and protein content and oil content, and both protein content and oil content were negatively correlated. Five district resources in the yield, protein content and plant-type traits are different, the oil content was not significantly different. The mid-stream area yields GCV, h_B ~ 2 are higher, with greater potential for selection. Oil content, low GCV protein content, h_B ~ 2 high, the choice of response, but there is still a need to create variation.
