Leaf Anatomical Evaluation of Some Soybean Genotypes Susceptible-Resistant To Cotton Leaf Worm

Abstract: ABSTRACT


The aim of this study was to identify leaf anatomical characters in soybean related to cotton leaf worm resistance, which could be used in indirect selection for insect resistance. The study carried out in the laboratory of cell study research department, field crops research institute, agricultural research center in 2005. A total of fourteen soybean (Glycine max (L.) Merr.) genotypes represent three categories of resistance to cotton leaf worm (Spodoptera littoralis ) were subject for leaf anatomical investigation related to varietal resistance to cotton leaf worm. Leaf hairs, cuticles of upper and lower leaf surface, epidermal cell type, mesophyll and vascular bundles features were studied in the young and adult leaves of all genotypes. Hair density and length, leaf cuticle thickness of lower epidermis, air spaces in the mesophyll tissue and vascular bundles size showed positive correlations with resistance to cotton leaf worm. The result indicated that the possibility for selection for hair length and hair frequency of the matured leaf with remarkable expected progress from selection for cuticle thickness of the leaf lower surface and mesophyll air space in the leaf. These traits would be useful as indirect selection for insect resistance genotypes.
