在南京生态环境下贵州大豆品种性状的遗传变异

THE PERFORMANCE OF THE GUIZHOU SOYBEAN NATIVE CULTIVARS IN THE TWO ENVIRONMENTS OF NANJING AND GUIYANG

在南京种植,与江苏品种比较,贵州品种的生育期偏短,株高、节数偏低,籽粒小,产量低,但荚多、蛋白质含高较高。在南京种植贵州品种,其生育期缩短,百粒重降低;生育期与淮北品种及淮南早熟品种较接近;其蛋白质、脂肪含量与其它性状的相关不同于长江下游的地方品种。在南京和贵阳生态条件下农艺性状间的相关也有差异。

The Guizhou soybean native cultivars planted in Nanjing showed a shorter growth period,less plant height and number of nodes on main stem,less 100-seed weight,lower yield,more pods per plant and higher protein content in comparison with the Jiangsu cultivars.Their growth period appeared similar to those of cultivars from north of the Huai River and of early type from south of the Huai River in Jingsu.The correlations of the protein and oil content with other agronomic traits of Guizhou native cultivars appeared different from those of the lower Yangtze valley soybean native cultivars.Also the correlations among agronomic traits of the cultivars in Nanjing showed some differences in comparison with those in Guiyang.
