Abstract
The current experiment was conducted at the Experimental Farm of Sakha Agricultural Research Station, Kafr El-Sheikh Governorate, Egypt for two seasons: 2022/2023 and 2023/2024. The studied faba bean genotypes were four commercial cultivars (Giza-40, Giza-716, Sakha-1, and Sakha-4) and four promising lines (L-1, L-2, L-3, and L-4). The 8 genotypes were evaluated to the reaction of natural infection with chocolate spot and rust disease. Sakha-4 and Sakha-1 performed better in terms of seed yield due to their good genetic traits, under scoring their potential for higher productivity of faba beans. L-1 and L-2, on the other hand, showed encouraging results in terms of high seed yield per hectare, and less infection with foliar disease. These two promising lines are good candidates for high yield and resistance to foliar diseases, which makes them a feasible choice for those who are looking for increasing faba bean productivity. Plant height, pod number per plant, seed yield per plant, and seed output per hectare all improved in faba bean genotypes, L-1, L-2, L-3, and L-4 due to their resistance to foliar diseases. These traits also improved the overall growth. On the other hand, vulnerability of Giza-40 to foliar diseases had a major effect on the components of yield and seed production. This study revealed that Shakh-1, Shakh-4, L-1 and L-2 are more productive due to their enhanced resistance to foliar diseases. Because L-1 and L-2 are resistant to chocolate spot and rust, they show potential in foliar disease breeding programs. Thus, they are strong contenders to improve crop productivity and quality.
