龙特浦A株型紧凑,植株高大,穗大粒多,所配特优系列组合优势强、高产,在广西区内推广时间长且面积较大。但是,龙特浦A的育性易受温光条件影响,会发生少量自交结实,杂种纯度难保。根据龙特浦A特征特性结合多年制种的实践,介绍了特优系列组合保质高产制种技术。 Longtepu A plant compact, tall plants, large spike large grains, with the advantages of superior combination of superior portfolio, high yield, in Guangxi area to promote a long time and larger area. However, Longtepu A’s fertility is vulnerable to temperature and light conditions, will occur a small amount of self-fertility, hybrid purity can not be guaranteed. According to Longtepu A characteristic characteristics combined with many years of seed production practice, introduced a combination of premium series of high-yielding seed production technology.
