Agromorphological Traits Variability of the Ethiopian Lentil and Exotic Genotypes

Abstract

Understanding the genetic relationships and diversity of Ethiopian lentil in relation to lentil from other countries is important in attempting to widen the genetic base of germplasm in the country. The objectives of this study were to generate information on agromorphological variability, to estimate PCV, GCV, heritability, and expected genetic advance of quantitative traits of lentil. 228 genotypes with different population types were studied for 11 agromorphological traits and rust disease severity score for two seasons (2011-2012) over three locations. The analysis of variance showed highly significant variations (P≤0.01) among genotypes for all characters studied. As per genetic parameter values, four groups of character were deduced. It is inferred that the exotic genotypes introduced from ICARDA showed rich genetic bases for 100-seed weight, number of seeds per plant, seed weight per plant, resistance source for rust, and high yielder in high yielding environment, where rainfall is not a major problem. Use the Ethiopian accessions for developing cultivars that could be used in double cropping and drought prone areas.

Genetic variability and character association among the yield and yield attributing components in lentil (Lens culinaris Medik.)

“…The presence of high heritability coupled with high-expected genetic advance indicated predominance of additive gene action in the expression of these characters and consequently greater chance of improving these traits through simple selection. These results are in conformity with the findings of Mekonnen et al (2014) for 100-seed weight and seed yield.…”

Agro-Morphological Characterization of Kenyan Slender Leaf (Crotalaria brevidensandC. ochroleuca) Accessions

“…Cluster analysis grouped the 29 slender leaf accessions into seven supported clusters based on the level of variation among the accessions. A similar strategy was applied by Zhang et al [30] and Mekonnen et al [31] on the agro-morphological characterization of Cucumis melo and lentils accessions, respectively. Diversity within supported clusters ranged from 0% (for singletons) to 45.07% as observed in Cluster 7. e high morphological diversity indicates a high potential of phenotypic selection which is a desirable aspect to plant breeders.…”

Genetic Variability and Character Association Study for Yield and Attributing Traits in Lentil (Lens culinaris Medikus.) under Terai Agro-climatic Conditions of West Bengal

“…. Abo-Hegazy et al [29], Mekonnen et al [30] and Sharma et al [31] reported 100 seed weight and pod plant -1 having a positive direct effect on yield plant -1 . on the contrary number of seeds pod -1 (-0.066), secondary branches plant -1 (-0.056), plant height (-0.042) and days to 50% flowering (-0.020) showed negative direct effect at genotypic level with yield plant -1 similar to that observed by Pandey et al [32].…”
