摘要: "早显A"是笔者用远缘杂交法选育的一个新不育系,经1990-1992年的初步研究,结果表明:"早显A"的早抽穗特性受一对呈不完全显性的基因控制,这与"珍汕93A"等当家不育系不同。用"早显A"与优良迟熟恢复系组配的F1代杂种,将早熟性与丰产性融为一体,对建立高产高效农业有重要价值。

Abstract: Zaoxian A is a new CMS line of rice developed by the authors through the distant hybridization. The experimental results from 1990 to 1992 indicated that:The early-heading characteristics or early maturity of Zaoxian A was a typical qualitative character and controlled by one pair of incomplete dominance genes, and so was different from that of the leading CMS lines Zhenshan 97A and V20A in China. The F1 hybrids derived from the crosses of Zaoxian A with good latematuring restorer lines combined the early maturity with high-yielding ability togetyer. Therefore, Zaoxian A was valuable to the breeding of hybrid rice and the construction of new agriculture with high-yielding ability and high economicaal profit.
