Evaluation of Genetic Variability of Some Local Grass Pea (Lathyrus sativus L.) Genotypes Using Different Statistical Analysis

Abstract

Background: The aim of this study was to determine the variation among local grass pea varieties in Türkiye by using some statistical analysis. Methods: The investigation was carried out according to the randomized block design with three replications during the growing season of 2018 and 2019 with 9 different genotypes and 2 registered varieties of grass pea at the Batı Akdeniz Agricultural Research Institute. Days to flowering, green herbage yield, dry herbage yield, seed yield, thousand seed weight, plant main stem length, the number of pods per plant, the number of seeds per pod, straw yield, biological yield and harvest index were determined. Furthermore, the results of investigated features were subjected to correlation, regression, path and cluster analysis. Result: The results showed sufficient variability in seed yield based on characteristics among the tested genotypes. Regression analysis showed that days to flowering, harvest index, number of pods per plant, straw yield and biological yield should be given more importance during selection. This study resulted in three clusters with the maximum intergenetic distance between genotypes Ls17 and Ls23. According to the results of the research, it was determined that genotypes Ls15 and Ls32 were equivalent to commercial cultivars in terms of the investigated characteristics. © 2023, Agricultural Research Communication Centre.
