摘要:

本研究对引自国外的135份藜麦种质资源的15个农艺性状进行了变异系数、遗传多样性指数、相关性分析、主成分分析和聚类分析。结果表明,该批藜麦种质具有丰富的遗传多样性。7个数量性状中,变异系数从大到小依次为：小区产量(57.83 %)> 单株粒重(57.37 %)> 茎粗(27.59 %)> 千粒重(22.50 %)> 株高(21.89 %)> 主花序长(19.38 %)> 生育期(13.89 %)；8个质量性状遗传多样性指数从大到小依次为：主花序色(1.44)> 籽粒色(1.43)> 茎色(1.38)> 籽粒形状(0.88)> 幼苗新叶叶色(0.79)> 主花序形状(0.78)> 籽粒光泽(0.63)> 子叶颜色(0.08)。主成分分析结果表明,前5个主成分累计贡献率达到66.537%。第1主成分主要与株型、花序型和生育期有关；第2主成分主要与植株和花序颜色有关；第3主成分主要与产量有关；第4主成分主要与籽粒大小形状有关；第5主成分主要与籽粒颜色有关。通过表型评价鉴定,初步筛选出早熟、矮秆、粗秆、大粒、长花序、结实率好、产量高的特异种质31份。

Abstract:

The variation coefficient, genetic diversity index, correlation analysis, principal component analysis and cluster analysis of 15 agronomic traits of 135 quinoa germplasm resources from abroad were carried out in this study. The results showed that the germplasm had abundant genetic diversity. Among the seven quantitative traits, the coefficient of variation from large to small is: Plot yield (57.83%) > grain weight per plant (57.37%) > stem diameter (27.59%) > 1000-grain weight (22.50%) > plant height (21.89%) > main inflorescence length ( 19.38%) > growth period (13.89%); The genetic diversity indices of eight quality traits were as follows: Main inflorescence color(1.44) > seed color (1.43) > stem color (1.38) > seed shape (0.88) > seedling new leaf color( 0.79) > main inflorescence shape( 0.78) > seed lustre (0.63) > cotyledon color (0.08). The principal component analysis results show that, The cumulative contribution rate of the first five principal components reached 66.537%. The first principal component was mainly related to plant type, inflorescence type and growth period; The second principal component was mainly related to plant and inflorescence color; The third principal component is mainly related to yield; The fourth principal component is mainly related to grain size and shape; The fifth principal component was mainly related to seed color. Through evaluation and identification of phenotypic , 31 germplasm with early maturity, short stalk, coarse stem, large grain, Long inflorescence ,good seed setting rate and high yield were selected.
