Abstract:: Thirty-three genotypes of red fescue were selected on the basis of diverse origin, anthesis date, and type of spreading from a space-planted introduction nursery. Open-pollinated, single-cross, and top-cross progeny nurseries were established into a randomized block with four replications, 20, 9, 8 entries, respectively, with nine plants per entry on...

Abstract:: The effectiveness of early generation selection for yield and yield stability and the possible identification of superior parental combinations were studied in winter wheat populations representing different levels of genetic diversity. Experimental material for evaluating yield stability consisted of nine bulk and seven modified bulk populations derived from nine parental...

Abstract:: Maturation rates of monogerm sugar beet seed grown in Western Oregon were measured quantitatively to determine attainment of maximum seed development and germination. Seed was collected at various intervals after anthesis from two hybrid varieties representing the extremes in resistance (hard bolting) and susceptibility (easy bolting) to seedstalk development. The...

Creator:: Moutray, Jim B., 1939-
Abstract:: Response to heterosis for plant height, anthesis date, panicle number, seed yield, and fall vigor rating was determined in a tall. fescue group selected for diverse morphology, origin, and anthesis date. Parents, single-cross progeny (SX), and first generation selfed progeny (S₁) were included in the study. Each experimental plot consisted...
