摘要:

研究旨在对湖南省47份生姜种质资源的15个数量性状和10个质量性状进行分析,以期探索湖南省各地生姜资源间的亲缘关系及变异特性,为湖南省生姜种质评价与新品种创制提供理论依据。用Excel及SPSS等对调查收集的农艺性状进行分析,结果表明,湖南省生姜资源具有丰富的遗传多样性,变异系数范围为13.22%~40.13%;聚类分析中,47份生姜资源分为2类4个亚组,其中第I类群的41份资源为密苗型资源,第II类群的6份资源为疏苗型资源,亚组I和亚组IV近似纺锤状;亚组II和亚组III近似灯泡状;主成分分析中,提取出的3个主成分累计贡献率达83.078%,分别命名为高产型形态因子、低产型形态因子和产量的叶部因子;相关性分析中,根状茎、株形、地上茎、子姜、叶部等形态因子与根状茎质量呈极显著正相关,分枝数和主茎叶数与根状茎质量呈极显著负相关,表明植株高大,分枝少,地上茎粗壮,根状茎、子姜粗长的品种单株根状茎质量相对更高;通径分析中,主茎叶数、分枝数对根状茎质量的直接通径系数为负,而根状茎、地上茎粗、子姜长、株高等对根状茎质量的直接通径系数为正,表明在一定范围内,生姜植株高大、地上茎秆粗壮、分枝少、叶片较少,根状茎粗长、子姜长的生姜品种具有高产潜力。该试验解析了湖南省生姜资源各主要农艺性状对根状茎质量形成的贡献大小,为更好地指导湖南省生姜生产提供了理论依据。

Abstract:

The purpose is to analyze 15 quantitative and 10 quality traits of 47 ginger germplasm resources in Hunan, to explore the genetic relationship and variation characteristics of ginger resources, and to provide a theoretical basis for the evaluation of ginger germplasm and the creation of new varieties. The agronomic traits collected from the survey were analyzed by Excel and SPSS. The results showed that there was abundant genetic diversity in ginger resources in Hunan, and the coefficient of variation ranged from 13.22% to 40.13%. In cluster analysis, 47 ginger resources were divided into two categories and four subgroups, of which 41 resources in group I were dense seedling resources, 6 resources in group II were seedling-thinning type, subgroup I and subgroup IV were spindle-like; subgroup II and subgroup III were bulb-like; the cumulative contribution rate of the three principal components extracted from the principal component analysis was 83.078%, they were named as high-yielding type morphological factor, low-yielding type morphological factor and leaf factor of yield, respectively. In the analysis, the morphological factors such as rhizome, plant shape, aboveground stem, zingiber, leaf and so on were positively correlated with the weight of rhizome, while the number of branches and leaves of main stem were negatively correlated with the weight of rhizome. The results showed that the weight of rhizome per plant of varieties with tall plants, few branches, strong aboveground stem and thick rhizome and zingiber was relatively high. In path analysis, the direct path coefficients of leaf number and branch number of the main stem to rhizome weight were negative, while the direct path coefficients of rhizome, aboveground stem diameter, zingiber length and plant height to rhizome weight were positive, indicating that in a certain range, ginger varieties with tall plants, strong aboveground stem, fewer branches, fewer leaves, and long rhizome and zingiber had high yield potential. This experiment analyzed the contribution of main agronomic characters of ginger resources to the formation of rhizome weight in Hunan, and could provide a theoretical basis for better ginger production.
