STUDIES ON SEED TRANSMITTED DISEASES OF SOME LEGUME CROPS

Abstract

Family Fabaceae is a wide spread family throughout the world. In

Egypt these crops is take a high concern for their high value of proteins.

Bean (Phaseolus vulgaris) has a special importance in Egypt having high value of nutrient contents. Bean seeds contain 22-27% protein and 65% carbohydrate. Cultivated area showed a continuos increase during the last few years. Results presented here can be summarized as follows:

1-Six pathogenic fungi were isolated from both foliage parts and seeds of chickpea i.e. Alternari alternata, Botrytis sp. Fusarium oxysporum ff. Sp., F. solani, Phoma sp. And Stemphylium sp. While, F. moniliforme was isolated only from foliage parts.

2- Eight fungi were isolated from foliage parts and seeds of cowpea i.e. Alternari alternata, Curvularia sp., Drechslera hawaiinsis, Fusarium moniliforme, F. oxysporum ff. Sp., F. solani, Phoma sp. and Stemphylium sp. 3- The highest number of fungi were isolated from both foliage

parts and seeds of bean (Phaseolus vulgaris). Isolated fungi could be arranged in ascending order as follows Rhizoctonia solani, Alternaria alternata, Verticillium sp. Macrophomina phaseolina, Botryodiplodia theobromae, Colletotrichum lindemuthianum, Sclerotinia sclerotiorum, Stemphylium sp. Fusarium solani, Fusarium moniliforme, Sclerotium rolfsii and Fusarium oxysporum f. sp. Phaseoli. C. lindemuthianum was recorded according to the available in Egypt literature for the first time.
