Abstract Cowpea pod borer (Etiella zinckenella) is considered one of the most destructive insects which causes great annual yield loss to cowpea in Egypt and different parts of the world. Using cultivars resistant to cowpea pod borer will help in reducing the environmental polution because the amount of insecticides which are usually used in controlling this insect will be much less. In addition this will help in reducing the harmful residual effect of the insecticides on the human beings. The objective of this research was to study the inheritance and nature of resistance to the cowpea pod borer to obtain genetic information which will be useful in designing breeding programs for resistance of cowpea to this insect. The research program of this study was conducted at the Faculty of Agriculture at Moshtohor; Department of Horticulture; using the wire screen house and the ”Preservation and Utilization of Primitive Germplasm”, Laboratory, during the successive seasons of 1993, 1994 and 1995 years. Parental Genotypes : The following cultivars/line were used in this research 1 - Carolina Cream: seeds of this cultivar were obtained from Dr. Richard L.Fery; U.S Vegetable Laboratory; Agriculture Research Service; South Carolina. This cultivar is known for its pod-resistance factor which prevent penetration of cowpea curcullio into pods. |
