摘要

目的。深入研究蚕豆育种现代方向的来源材料,以进一步利用在乌克兰森林草原创造高产品种。方法。根据植物育种、种子和作物生产中普遍接受的和特殊的方法,进行田间、形态计量、统计、分析。结果。介绍了蚕豆绝对数量性状和相对数量性状的改良变异研究结果,探讨了数量性状间的相互关系,确定了生产力结构中各要素对总产量的贡献。已鉴定出环境稳定指标和简单指标,并建立了可用于基因型鉴定和选择的性状。蚕豆植株绝对数量性状具有较高的变异率,采用株高和单株节数等性状进行基因型鉴定较为适宜,变异系数在10%以内。对蚕豆而言,最稳定的环境指标是收获指数、单豆种子数、节间长和微分布指数。通过相关分析发现,蚕豆品种的种子产量与地上株质量、单株豆数、单株种子数、单株荚果重密切相关。结论。这些研究使蚕豆的绝对性状和相对性状得到了生态稳定指标、生态变异率小于原性状变异率的简单指标的鉴定,并通过对种内蚕豆数量性状关系的相关分析,鉴定出了一些应用于饲料蚕豆育种的性状。

Regularities of formation of quantitative morphometry of fаba bean plants in the system of variation-correlation analysis.
Purpose. The in-depth study of the source material for modern directions of faba bean breeding for further use in the creation of high-yielding varieties in the Forest-Steppe of Ukraine. Methods. Field, morphometric, statistical, analyzes on the basis of generally accepted and special methods in plant breeding, seed and crop production. Results. The results of the study of modification variability of absolute and relative quantitative traits of faba bean plants are presented, the interrelation of quantitative traits is investigated and the contribution of individual elements of the productivity structure to the total yield is determined. Environmentally stable indicators and simple indices have been identified, and traits that can be used for genotype identification and selection have been established. Given the high variability of absolute quantitative traits of faba bean plants for genotype identification, it is advisable to use the traits of plant height and number of nodes per plant, where the coefficients of variation were less than 10 percent. For faba beans, the most environmentally stable indices are the harvesting index, the number of seeds per bean, internode length, and the microdistribution index. According to the correlation analysis, it was found that the seed productivity of faba bean varieties is closely correlated with the following indicators: aboveground plant mass, number of beans per plant, number of seeds per plant, weight of pod flaps per plant. Conclusions. These studies allowed to identify absolute and relative traits of faba beans with ecologically stable indicators, simple indices, the ecological variability of which is less than the variation of the original traits, the correlation analysis of the relationships of quantitative traits of faba beans within the species allowed to identify a number of traits that should be used in fodder beans breeding.
