油用向日葵的单株产油量是受多基因控制的复杂数量遗传性状。多年来我国很多育种工作者撰写油葵研究文献,但在这方面的报道还不多。为了提高对油葵高产品种的正确选择,明确各性状对产油量所起的直接和间接的作用及其相对重要性,从而给今后育种工作提供确切的性状选育依据,本文对5个油葵品种的几个植物学性状与单株产油量进行遗传相关分析及产油量组成因素的通径分析。一、材料和方法试验在本所进行,参试品种有:76—64A×内5,先进工作者,75—33A×内5,76055A×181,74102A×181。随机区组设
Oil yield per plant with sunflower is a complex number of genetic traits controlled by multiple genes. Many breeders in our country have written literature on oil sunflower for many years, but there are not many reports on this. In order to improve the correct choice of high-yielding varieties of sunflower, clarify the direct and indirect effects of each trait on oil yield and its relative importance, so as to provide exact breeding basis for future breeding work. In this paper, Genetic Correlation Analysis and Path Analysis of Components of Yield of Several Botanical Characters of Kwai Kwae and Single Plant. First, the material and method test carried out in the Institute, the test varieties are: 76-64A × within 5, advanced workers, 75-33A × within 5,76055A × 181,74102A × 181. Random block set up
