关于高粱的开花特性,国内外曾有过报道.但由于所用试材或试验条件的不同,其结果差异较大.特别是前人研究所用的试验品种,在当前生产上已不再用,因此,为了实际应用,我们选用生产上几个常用高粱亲本,特设区对其开花特性做了进一步研究分析,期望对高粱育种、亲本繁育及杂交种生产提供一个方面的实验依据. About the flowering characteristics of sorghum, there have been reports at home and abroad.But because of the different test materials or test conditions, the results vary greatly.Especially the test varieties used in previous studies, in the current production is no longer used, therefore In order to be practical, we chose the parents of several commonly used sorghum in the production, and further analyzed and analyzed the flowering characteristics of sorghum. The expectation is to provide an experimental basis for the sorghum breeding, parental breeding and hybrid production.
