Abstract:
Background and Objective: Lupin (Lupinus albus L.) is an annual grain-legume widely harvest and cultivated in Egypt and also worldwide. Lupin seeds are utilized as food for the human and livestock nutrition. The objective of this investigation was to evaluate the performance of 50 lupin genotypes for yield, yield components and chemical compositions. Materials and Methods: Fifty lupin genotypes were collected from different regions in Egypt and Australia to evaluate and determine the relationships between lupin yield and yield components in a randomized complete blocks design (RCBD) with 3 replications and to show the efficiency of components on seed lupin yield by using different statistical procedures (correlation and cluster analysis). Results: Highly significant differences were found between the 2 seasons for number of pods/plant, number of seeds/plant, seed yield/plant, seed index and seed yield/plot), indicating wide variation among seasons and there were no differences between morphological characters (plant height and plant height from nod). The seed chemical analysis showed that the genotypes differed in their biochemical composition for moisture, protein, fat, fiber, ash and carbohydrate. Seed yield/plant was significantly and positively correlated with No. branches/plant (r = 0.609**), No. of pods/plant (r = 0.885**), No. of seeds/plant (r = 0.713**), seed index (r = 0.709**) and plot weight (g) (r = 0.884**). The cluster analysis showed that Fayed 3 and Abo-Soeir 2 genotypes were with very low seed yield/plant. And Sakolta, Edfo and X1/90/72 genotypes showed highest protein content. Conclusion: Based on the results, agreed upon that high lupin seed yield of genotypes could be obtained by selecting breeding materials with high number of seeds/plant, high number of pods/plant and genotypes with highly protein seed content for improving lupin breeding programs.
