| Abstract | ||||
| Thirteen faba bean (Vicia faba L.) genotypes and local variety Sakha 1 were evaluated for resistance to Liriomyza trifolii (Burgess) and Nezara viridula L. under field conditions of north Delta, Kafr El- Sheikh governorate during two successive seasons;2010/11and 2011/12. Based on the grand mean of every insect in the two seasons, the results indicated that the highest number of L.trifolii larvae took place on genotype H-240A and H-240B, while the least number was recorded on H-1972B. The genotype H-1988 received the highest number of N. viridula, while the other genotypes exhibited low number without significant differences. According to the resistance degree to L. trifolii, the genotypes H-240A and H-240B appeared as highly susceptible, H-1970; H-1972A; H-1973; H-1988; H-1992 and H-243 appeared as susceptible, H-232; H-244 and Sakha 1 showed relatively resistant, H-230 showed moderately resistance, while H-1972B showed resistance. As for N. viridula, the genotype H-1988 appeared as highly susceptible; H-1970; H-1972A; H-1980; H-230; H-232; H-240A and H-243 appeared as susceptible, H-1973; H-1992; H-240B; H-244 and Sakha1 showed relatively resistance. The rest genotypes showed moderately resistance. Finally, it could be concluded that the genotype H-1972B exhibits resistance to the two considered insects, consequently it can be involved in breeding programs as a source of resistance under north delta conditions. | ||||
