Comparative study on the performance of 14 oat (Avena sativa) germplasm inHuangcheng Town of Sunan County, Gansu Province

In order to screen suitable oat germplasm for planting in Huangcheng Town of Sunan County, the adaptability of 14 oat (Avena sativa) germplasm were studied by testing the height, yield, nutrition component, seed yields, 1 000-grain weight, and germination rate. The results showed that the height of Qingyongjiu No.479 was the highest(151.3 cm), while Qingyongjiu No.474 was the lowest (128.4 cm). The tillers of Qingyongjiu No.12 was 2.0, which was higher than other oats germplasm. The leaf-stem ratio ranged from 1.79 to 2.46. The hay yield of Longyan No.2 was the highest(11.11 t·ha-1), while Bayan No.3 was the lowest(7.71 t·ha-1). The crude protein content of Qingyongjiu No.416 was 8.2%, which was higher than other oats; while Qingyongjiu No.195 was the lowest(6.3%). The acid detergent fiber content of Qingyongjiu No.97 was 47.4%, which was higher than other oats; while Jiayan No.2 was the lowest (37.4%). The neutral detergent fiber content of Longyan No.2 was 66.7%, which was higher than other oats; while Qingyongjiu No.233 was the lowest (59.5%). Among all oat germplasm tested, only five oats:Bayan No.3, Qinghai No.444, Qingyongjiu No.93, Qingyongjiu No.474 and Gannan could finish whole growth period local area, the 1 000-grain weight, germination rate and seed yield of Gannan was higher than other four oats. Comprehensive analysis showed that Qingyongjiu No. 479, Qingyongjiu No. 167 and Qingyongjiu No.233 were suitable for agriculture production in Huangcheng Town of Sunan County.
