中文摘要：用种量大,制种产量低是限制杂交小麦大面积推广的关键问题之一。以烯效唑、Openall、硼肥3种化学物质处理小麦不育系,旨在选择提高杂交小麦制种产量的化学物质组合。结果发现,每公顷喷施烯效唑5%粉剂112.5 g和硼砂2 505 g,制种产量可提高22.2%,异交结实率提高6.6个百分点,开颖角度明显增加。

外文摘要：High seed consumption and low seed production is one of the key issues to limit large scale hybrid wheat promotion.This study mainly coped with male sterile lines based on three chemical treatments of uniconazole,Openall and boron and aimed to choose chemical composition which could increase hybrid wheat seed production.The results showed that spraying uniconazole of 5% powder 112.5 g and borax 2 505 g per hectare,seed production could increase 22.2%,outcrossing rate added 6.6 percentages,angle of glume opening increased significantly.
