The Yielding Ability Of Bulked F2 Barley Crosses And Parents In Comparative Yield Trials, Walter Lowell Nelson

Electronic Theses and Dissertations

Present methods of breeding new barley varieties are costly, laborious and lengthy. Populations from a cross are grown until they become homozygous before much selection by comparative yield trails can be made. The pedigree method limits the number of crosses that can be studied because of the large segregating populations necessary for the expression of desired gene combinations. Because of the enormous amount of work involved, it would be highly desirable for a plant breeder to work only with superior parental material. The capabilities of a plant breeder would be greatly increased by an method which would allow him to …
