White lupin (Lupinus albus L.) is rich in quality protein, relatively tolerant to drought, soil salinity and acidity, increase the fertility of soils and can contribute to improved agricultural sustainability, food security and reduce malnutrition which has close associations with climate change. This study was conducted to assess genetic variability of white lupin genotypes for agronomic traits and nutrient contents of grain, and to estimate association of traits. Twenty-five genotypes of white lupin were evaluated for 29 quantitative traits in 5 x 5 simple lattice designs at Holeta Agricultural Research Center during 2018/2019. The variations of genotypes for yield and grain protein content ranged from 122 to 3206 kg ha-1 and 28.55 and 35.81%, respectively. The genotypes had 2763, 772.3 and 81.59 mg/kg of average phosphorus, calcium and iron contents of grain. The PCV and GCV coefficient of variations varied from 4.39 to 29.54% and 3.41 to 28%, respectively. Heritability in broad sense and genetic advance as percent of mean ranged from 42.07 to 88.94% and 5.34 to 53.98%, respectively. The estimates of GCV, PCV, H2 and GAM were high to moderate. The research results showed the presence of variations among landraces of white lupin in Ethiopia and further evaluation of germplasm could be rewarding to improve the genetic resource in the country.
