Abstract
Ecological model for organizing the quantitative traits and the method of orthogonal regressions were applied to evaluate both, aboveground and root biomass of grass pea varieties different originating. The study was conducted for three years. The highest yields for fresh aboveground biomass were BGE015741 (840.40 kg/da), LAT4362 (779.3 kg da-1) and BGE027129 (722.80 kg da-1). Plants of LAT4362 and BGE025277 have a higher weight of fresh aboveground mass and fresh root mass and exhibit a good combination of adaptive and attraction genes. The highest average seed yield was recorded at BGE015741 (158.40 kg da-1), BGE027129 (113.10 kg da-1) and BGE025277 (108.30 kg da-1). The BGE027129, BGE025277 and BGE015741 varieties are found of greatest interest with regard to seed weight per plant and they are suitable as initial materials for the purpose of combinatorial breeding for the obtaining of genotypes combining both, high seed weight and high root biomass weight per plant.
