- Abstract:
- In order to breed high-yield widespread new soybean varieties suitable for planting in different ecological regions of Guizhou province, the high-yield and widespread new spring soybean variety Qiandou 12 was bred by pedigree selection method using the new materials. The average yield of Qiandou 12 was 3 073.2 kg?ha-1 with the protein and the fat content of 43.76% and 19.20%, respectively in regional experiment in Guizhou province. The agronomic characters of Qiandou 12 were as follows: Growth period 114.2 d, plant height 50.5 cm, the number of main stem nodes 12.9, branch number 1.95, pod number 36.35, seed number per plant 65.05, weight per plant 13.95 g, 100-seeds weight 24.05 g, purple flower, gray hair, limited podding habits, compact plant type, oval leaves, yellow seed coat, brown seed umbilicus, moderate resistance to soybean mosaic virus. Qiandou 12 was suitable for different planting methods in different ecological regions in Guizhou province.
