| Abstract: | Jingfu2A was developed from the cross Xieqingzao A/Jingfu2B by successive backcrossing to Jingfu2B, which had been derived from Gan46B/Xieqingzao B. It's characteristics include high grain quality, high yield, ideotype. And It is early-CMS line that it is a piece of comprehensive properties to behave outstandingly.In July, 2002, it was registered in Fujian Province. According to the method of gray judgment, The F1 hybrid rice combinations of Jingfu2A were selected. The results showed that Jingfu2A/shuhui881, Jingfu2A/mianhui725 and Jingfu2A/CDR22 were excellent. |
