Studies on Ear-SCab resistance of wheat plants. 2. Genetical factors affecting on the inheritance of Ear-SCab disease of wheat plants.

Abstract

7 crosses was applied to study on the inheritance of Ear-SCab in wheat plants which attacks the kernel and segregation ratios obtained was as follows ;From these results, the inheritance of Ear-SCab resistance was proved to be 3 factors in the generation of both F2 seed and F2 plant. The method of testing of Ear-SCab resistance is that : infected percentage was decided by the percentage of the spike or kernel attacked by fungus to the total ones per plant. Healthy kernels contain the healthy and imcompletely healthy ones which developed by the effect of the infection.
