| Abstract | ||||
| The present study was carried out at Sakha Agricultural Research Station, Kafr El-Sheikh governorate, Egypt during 2020/21 and 2021/22 seasons to study the behavior of eleven faba bean promisingbreeding lines i.e., (L1 (Giza 2 x Misr1), L2(Sakha 3 x Giza 2), L3(Giza843 x Misr 3), L4 (Nubaria1 x Misr 3) , L5 (Misr 1 x Giza843) , L6(Nubaria 3 x Misr 1) , L7 (Sakha 1 x Misr 1), L8 (Triple white x Giza429), L9 (Giza40 x Giza429), L10 (Ohishima-Zaira x Giza 429) and L11(Giza 429 x Sakha 4) compared with four commercial cultivars Sakha 4 and Nubaria1 (susceptible to Orobanche crenata), Misr1 and Giza843 (tolerant to Orobanche crenata). The obtained results showed that under the non-infested soil with Orobanche, L7 genotype (Sakha 1 x Misr 1) was better in producing the highest number of branches/plant, number of pods, number of seeds per plant and seed yield per feddan without significant difference from L6 (Nubaria 3 x Misr 1) faba bean genotype and surpassed the commercial varieties in the studied traits during both seasons. Under Orobanche crenata infestation, L6 and L7 genotypes exceeded the other tested faba bean genotypes in most studied traits and recorded the highest values for number of branches, pods and seeds per plant and yielded 7.42 and 7.15 ardab/fed of seeds respectively as an average of the two seasons. The lowest number of Orobanche spike, during this study. Based on theobtained results, it could be concluded that L6 and L7 breeding lines surpassed all tested genotypes under both free and infested soils with Orobanche crenata and produced the highest seed yield in addition to the resistance against chocolate spot and rust diseases. So, both breeding lines deserve further evaluation in advanced yield trials to release the best as a new faba bean cultivar tolerant to Orobanche and resistant to foliar diseases along with the high yield potentiality, results of seed quality traits revealed significant differences among genotypes under the two soils, in both seasons. The genotypes L7, L6 and Giza843 gave the highest values of crude protein, total carbohydrates and total tannins contents, respectively while Nubaria1 gave the lowest values. | ||||
