Abstract

Estimation of the level of durum wheat germplasm genetic diversity is important for its classification and efficient use in breeding programmes. The aim of this study was to assess genetic diversity of durum wheat genotypes developed at the Institute of Field and Vegetable Crops in Novi Sad, Serbia, with 26 morphological characteristics based on the International Union for Protection of New Varieties of Plants guidelines. The Shannon diversity index was used as an indicator of morphological diversity and it ranged from 0.283 for glaucosity of lower side of the flag leaf blade and density of hairiness of uppermost node of the culm, to 0.950 for the ear colour, with the mean value of 0.616, indicating a medium to high level of morphological diversity. On average, the diversity was higher for traits relating to generative organs than for those associated with vegetative plant organs. The 21 morphological characteristics were sufficient to distinguish unique profiles of all durum wheat genotypes. The estimation of varietal diversity and identification of morphological characteristics with the highest discriminative power were done by multiple correspondence analysis. The traits that contributed the most to the distinction of genotypes were the ear colouration, length of beak of the lower glume, lower glume shape, ear length of awns at tip relative to ear length and colour of awns. Morphological characterization using the traits with the highest discriminative power could be a useful complementary method for durum wheat germplasm classification and diversity analysis.
基于upov定义特征的塞尔维亚硬粒小麦基因型特征
硬粒小麦种质资源遗传多样性水平的评估对其分类和育种规划的有效利用具有重要意义。本研究的目的是根据国际植物新品种保护联盟指南,评估塞尔维亚诺维萨德大田和蔬菜作物研究所开发的具有26个形态特征的硬粒小麦基因型的遗传多样性。以Shannon多样性指数作为形态多样性的指标,其范围为旗叶下侧的白霜度和茎上节的毛密度为0.283,穗色为0.950,平均值为0.616,表明其形态多样性处于中高水平。平均而言,与生殖器官相关的性状多样性高于与营养器官相关的性状多样性。21个形态特征足以区分所有硬粒小麦基因型的独特特征。利用多重对应分析对品种多样性进行估计,并鉴定具有最高判别能力的形态特征。对基因型差异贡献最大的性状是穗色、下颖片喙长、下颖片形状、芒尖相对于穗长和芒色的穗长。利用鉴别力最高的性状进行形态鉴定,可作为硬粒小麦种质分类和多样性分析的有益补充方法。
