Sažetak
Field pea (Pisum sativum L.) is one of the most important protein legumes. Although grain yield is the most important breeding trait, the focus of the breeding process is also directed at other quantitative traits (yield components). The study of genotypes (breeding lines) in different environments through the analysis of the most significant quantitative properties, as well as the assessment of their interaction values, contributes to the creation of new sources of genetic variability and new genetic material (varieties/hybrids). The study goals were to evaluate the agronomic value of nine newly created spring breeding lines of fodder pea during 2019 and 2020, to evaluate the stability of yield components and to select the most promising genotypes for further breeding procedures based on the obtained results. The results of the study showed that there are significant differences between the tested genotypes in the tested environments for most of the analysed properties and that the variation of genotypes has the greatest influence within the identified sources of experimental variation. The stability assessment was made by the grouping method according to Francis and Kannenberg, based on which the values of the genotypes L – OSMBK 1, L – OSMBK 3 for grain/plant yield L – OSMBK 1, L – OSMBK 8, L – OSMBK 3, L – OSMBK 9 for 1000 seed weight and L - OSMBK 9 for the plant height were in group I, which is characterized by high values and a small coefficient of variation of properties and represents the most stable and most promising breeding genotypes.
