In the past, majority of the plant breeding programmes were focused mostly on developing the cultivars with high yields. Recently, stable, quality and reliable yields under various environmental conditions have consistently gained importance over solely increased yield. The experiment was conducted during the period 2019-2021 at the National Agriculture Research Development Institute Fundulea in order to establish the phenotypic and genotypic correlations between the main quantitative traits in eight winter pea genotypes. The highest positive correlation was found between plant height and grain yield (r = 0.99***), the number of pods per plant with number of grains per plant (r = 0.90***) and grain yield (r = 0.87***) and plant height (r = 0.80***), the grains weight per plant with earliness (r = 0.83***); the highest negative correlation was registred between earliness and plant height (r = -0.83***), grain yield and earliness (r = -0.82***). Pea breeding should be focused on traits with consistent heritability and a positive effect on seed yield when selecting high-yielding genotypes, and on allowing for more widespread use of pea in various agricultural production systems.
