Genetic Variation Among Egyptian White Lupin (Lupinus Albus L.) Genotypes

Abstract

Field Evaluation of eighteen lupin genotypes was carried out during 2012/13 and 2013/14 at Giza Agriculture Research Station, Egypt, to assess the genetic variation on phenological parameters. Simultaneously, molecular diversity assessment was performed using 11 SRAP primer pair combinations. High significant differences among genotypes were observed for field performance during the two seasons and their combined data. The Australian genotype 75 B9.10 and landrace Fayed1 recorded the highest seed yield/plant while the Egyptian landraces Sohag2, Fayed1 and the cultivar Giza1 were superiors in seed yield/hectare (2.8, 2.6 and 2.6t, respectively). Only the first two principle components explained 97 % of variability. Characters, number of pods, seed yield/plant and seed yield/hectare were grouped on the positive PC1 axis of the biplot with genotypes Sohag2, 75B9.10 and Fayed1. The molecular analysis revealed coherent results. The 11 SRAP primers generated 3286 amplified fragments represents 337 genetic loci across the lupin genome. The average detected loci per primer pair was 30.64 with 322 polymorphic loci across the studied genotypes (96.05%). The polymorphism information content (PIC) values were generally high and ranged from 0.883 to 0.981. The high PIC values highlight the power of SRAP markers in detecting the molecular diversity in lupin genotypes. The genotypes tended to cluster based on their origin and genetic background.

Genetic Variability, Heritability and Genetic Advance for Some Yield and Yield Related Traits Among 36 Ethiopian White Lupine (Lupinus albus L.) Genotypes

“…This result can be supported by the idea of very recently published research work Lupinus albus L. landraces can grow up to 146 cm tall [12]. In the study carried out by [28] the maximum seed yield per plant was reported as 38. 3g which is more approached to the minimum value of SYP obtained in this research.…”

“…Lupine (Lupinus albus L.) is a leguminous plant that is rich in high good quality protein percentage (44%), and seed dry matters like oil and dietary fiber, lupine cultivation reached to 661 thousand hectares in 2013 with Australia, Russian Federation and Ukraine as the world's highest production areas (El-Harty et al 2016). In Egypt, Lupinus is cultivated in different soil types because its agricultural requirements are very low.…”

Mediterranean White Lupin Landraces as a Valuable Genetic Reserve for Breeding

“…Yet, limited number of studies on white lupin molecular diversity are cited in the literature. To the best of our knowledge, genetic diversity using molecular markers has been estimated for local germplasm from Ethiopia [42,52] and Egypt [53].…”
