| Abstract: | Zhe 94A is a new indica CMS line with large panicles and good grain quality. It is developed from crossing V20A to selected F3 plants of Zhenong 8010B/Zhe 94 with large panicles and high stigma exsertion rate, followed by successively backcrossing to the corresponding selected paternal plants. It has a complete male sterility with 100% of sterile plants, 99.94% of pollen sterility and 99.98% of spikelet sterility. Compared with the check CMS line Xieqingzao A, it has stronger combining ability, better grain quality, larger panicles, earlier maturity, higher stigma exsertion rate and better blast resistance. It was technically identified in Zhejiang Province in September 2003. |
