本文分析了18个油用型向日葵杂交种10个性状的遗传力、遗传进度,以及单盘产量、单盘油产量与其他性状的相关性。各种性状遗传力以子实含油率最高,盘径最低。遗传进度以油产量最高为22.39％,盘径最低为3.62％。产量与各性状的相关遗传进度以子仁含油率最高为12.16g/盘,株高最低为1.84g/盘。油产量与各种性状的相关遗传进度为子仁含油率最高为6.179/盘,皮壳率最低为-1.41g/盘。叶数与产量、油产量的相关遗传进度都较高,分别为11.40g/盘和4.00g/盘。本研究中产量和油产量与株高相关均不显著,株高与叶数的相关也不显著。所以,可望选育出矮秆(应保证叶数)、高产、高油的油用型杂交种。
This article analyzed the heritability and heritability of 10 traits of 18 hybrid sunflower cultivars, and the correlation between single trawl yield, single traw oil yield and other traits. Heritability of various traits with the highest seed oil content, the lowest diameter. Genetic progress to the highest oil production was 22.39%, minimum disk diameter of 3.62%. The relevant genetic progress of yield and traits was that the highest seed oil content was 12.16g / pan and the lowest plant height was 1.84g / pan. The genetic progress related to oil yield and traits was that the highest oil content of Zixin was 6.179 / pan and the lowest skinning rate was -1.41g / pan. Leaf number and yield, oil production related genetic progress is higher, respectively 11.40g / plate and 4.00g / plate. In this study, there was no significant correlation between yield and oil yield and plant height, and the correlation between plant height and leaf number was not significant. Therefore, it is expected to breed dwarf (should ensure the number of leaves), high yield, high oil hybrid oil type.
