中部地區秋作型大豆選育

Abstract

本試驗旨在探討中部地區雙期作稻田及沿海再生稻區，進行大豆適栽品種選育。由美國農部種原引種材料中，選育秋作產量高、無紫斑及不裂莢之品系 (PI518288 (Pai Mei Tou)、PI548480 (Palmetto)、PI548436(Acadian)、PI265497 (Acadian)、PI51824 (Ai Chia Tou)、PI518285 (Hei Pai Mei))。選育秋作型大豆在植株高度上可較高雄選10 號至少高5.97 cm，在百粒重上，高雄選10 號為17.1 g，選育秋作型大豆百粒重介於14.33~15.59 g，最後在公頃產量表現上，較高雄選10 號可增加55%以上，最高增加755 kg。同時由美國農業部種原庫引入PI518283等台灣種原48 個品系進行秋作大豆純化試驗。 For the purpose of autumn soybean breeding experiment on the rotation area, which were included double cropping paddy field, regeneration area of Taichung area. Firstly, From the original introduction materials of the US Department of Agriculture, breeded lines with high yield, no purple spots and no split pods, were contained,PI518288 (Pai Mei Tou), PI548480 (Palmetto), PI548436 (Acadian), PI265497 (Acadian), PI51824 (Ai Chia Tou), PI518285 (Hei Pai Mei). The selection of autumn crop soybean varieties can be higher than KSS10, which were at least 5.97 cm in plant height. Among the 100-seed weight, KSS10 was 17.1 grams and heavy, but autumn soybean varieties were light and range from 14.33 to 15.59 grams. Finally, on terms of hectare yield performance, autumn soybean varieties were the higher KSS10 ,which were increased by more than 55%, and the maximum increase were 755 kg. At the same time, we introduced 48 strains of Taiwan germplasm which were obtained from the USDA. These germplasm will be used to test and evaluate in the future.
