Types of spring wheat resistance to root rots and parent material for breeding
The results of studying soft spring wheat parent material characterized by relatively high resistance and tolerance to root rots that can be used as sources for disease resistance are given.
An analysis of the nature of the gene action for seven characters influencing productivity and wide adaptation in Linum usitatissimum L. was undertaken in this investigation over three seasons based on diallel and fractional diallel crosses, among a set of ten genetically diverse parents. Estimation of combining ability and the nature of geno-type-environment interactions for the above characters was also examined.
