THE STUDY OF GENETIC VARIABILITY WITHIN THE COLLECTION OF PEANUTS GROWN ON THE SANDY SOILS OF SOUTHERN OLTENIA

Abstract

The experiment studied the genetic variability of production and some productivity elements in peanuts grown on sandy soils at Research Development Station Plant Culture Sands Dabuleni  during 2018-2020. Several genotypes of local and foreign peanuts were studied. The highest coefficient of variation was recorded at number of secondary branches per plant, number of immature pods, number of mature pods, number of gynophores forming pods, pod production and grain weight per plant. Pod yield per plant showed a highly significant and positive correlation with number of pod-forming gynophores, number of mature pods per plant, grains weight per plant, and days to 50 percent flowering. The number of mature pods per plant was positively correlated with pod yield per plant. Therefore, the number of branches per plant, the height of the main stem, the number of pods per plant, the weight of pods per plant, the number of days to 50 percent flowering, the percentage of shelling and the number of days to maturity are the most important characters that would could be used in selection to increase production.
