Abstract
One of the most important tasks of breeders is to improve the properties of breeding material (varieties, lines) and to create a new genetic variability. The study goals were as follows: during two consecutive years (2019 and 2020), to evaluate the agronomic value of nine newly created spring breeding lines of fodder pea, as well as to evaluate the stability of yield components and to select the most promising genotypes for further breeding. The results of the study demonstrate that there are significant differences between the tested genotypes in the tested environments for most of the analyzed properties and that the variation of genotypes within the identified sources of experimental variation exerts the greatest influence . Based on the investigated property values, subsequent to stability evaluation the desirable genotypes L - OSMBK 1, L - OSMBK 3 – for the grain/plant yield L - OSMBK 1, L - OSMBK 8, L - OSMBK 3, L - OSMBK 9 – for the mass of 1,000 grains, and L – OSMBK 9 – for plant height were identified as the stable genotypes, with a high breeding and agronomic properties.
