Abstract

Many times the plant pathologist and plant breeder are confronted with a plant disease which requires the development of a resistant variety in a limited time. Any breeding program which requires selection from a large population during each segregating generation to insure the right genetic combination will, of course, lengthen the period which it will take to develop this resistant variety. The backcross method of plant breeding, in many cases, helps the plant pathologist and plant breeder develop resistant varieties containing characteristics similar to those of the desired parental type within a shorter period of time.
