【摘要】 过去40年中,国内外先后建立了多种技术体系来利用小麦的杂种优势。评价一种技术体系是否具有实用价值或潜在利用价值,最根本的是杂交种的优势、纯度和成本。温光敏两系杂交小麦是我国自主发明,也是目前进展最快的小麦杂种优势利用途径之一。过去9年的研究与应用实践证明:温光敏两系杂交小麦是目前最适于云南的小麦杂种优势利用途径,具有明显的实用价值和应用前景。
【Abstract】 Several breeding systems of hybrid wheat have been set up during past 40 years for the utilization of heterosis at home and abroad. Whether a system is practicable basically depends upon the heterosis, purity of hybrid and the cost of hybrid seed. The system of two-line hybrid wheat, independently established by China with thermo-photo-sensitive genie male sterile wheat, is becoming one of the fastest ways in the utilization of wheat heterosis, results from researches and practices in past 9 years show that this system is much adaptable, practicable and promising in Yunnan province.
