摘要
武金２Ａ为一新育成的籼型优质不育系，具有马尾粘胞质。其不育性彻底，不育株率１００％，不育度９９．８７％以上；碾米品质和营养品质达部颁一级优质米标准，外观品质和蒸煮品质亦较好；开花习性好，繁殖制种产量高；一般配合力好，所配组合武金２Ａ／９５８，武金２Ａ／７２５和武金２Ａ／４５２１等比对照汕优６３增产５．３２％～２５．３９％。
Wujin 2A is a newlydeveloped fine quality indica CMS line with the cytoplasm of
Maweizhan, a local rice variety in the western part of Hubei Province. Its sterility is complete
with 100% sterile plants and >99.87% pollen and seed sterility. Its milling and nutritional quality
traits are all up to the standards of the first class fine quality rice issued by the Chinese
Agricultural Ministry (CAM) with relatively good appearance and cooking quality. It is easy to
achieve high yield in its multiplication and hybrid seed production for its good flowering habit.
Its F1 hybrids such as Wujin 2A/958, Wujin 2A/725 and Wujin 2A/4521 yielded 5.32%25.39%
higher than check Shanyou 63 in the yield trial in 1997.
