摘要
通过明恢63∥泰引1号/IR26杂交选育而成的水稻恢复系绵恢501,具有恢复度高、配合力强、抗病性好、制种产量高、杂种优势强等特点,与野败型、冈型、D型、印尼水田谷型等不育系配组,均表现出较强的杂种优势和优良的综合性状,其中Ⅱ优501、二汕优501、D优501和冈优501已先后通过四川省品种审定委员会审定,并在南方稻区大面积示范推广。
Mianhui 501, an indica restorer in rice, was developend from the cross of Minghui 63∥Taiyin 1/IR26. It is characteristic of strong restoring ability, good combining ability, good disease resistance and high yield of hybrid seed production. The hybrids by crossing it to various types of CMS lines such as WA type, G type, D type and IP type CMS lines showed strong heterosis and good integrated agronomic traits. Its combinations of Ⅱ You 501, Ershanyou 501, D You 501 and Gangyou 501 were examined and approved for release in Sichuan Province in 1993~1996, and have been planted to about 2 million hectares in the provinces of Sichuan, Hubei, Yunnan and Guizhou since 1991.
