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.
