Creator:: Charoenwatana, Terd, 1937-
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...

Creator:: Nebeker, T. Evan
Abstract:: A population of the Douglas-fir cone moth, Barbara colfaxiana (Kft. ), was studied on the Buckhead Seed Production Area, Oakridge, Oregon, during 1971 and 1972. A method of estimating cone and insect populations is presented. Factors contributing to the mortality of B. colfaxiana are discussed, with resinosis being the critical...

Creator:: Frederickson, Leslie John
Abstract:: Responses to two cycles of mass selection for heading date, followed by selfing or intermating, were studied in two diverse winter wheat (Triticum aestivum L. em. Thell) crosses. Selection was bidirectional, resulting in early and late populations for each mating system, cycle, and cross. The influence of mass selection for...

Creator:: Buehner, Heidi Renata
Abstract:: Two management systems were evaluated in terms of the effects on cow condition score and body weight changes and calf growth rates. The management systems evaluated were winter supplementation of energy, winter creep feeding and delayed weaning. The calves used in this study were born in September and October of...

Creator:: Amos, James Franklin
Abstract:: The effects of mold level (Botrytis cinerea), processing method (fresh, individually quick frozen (IQF), frozen sugared sliced (FSS), freeze dried (FD), canned, and preserves), and maturity (underripe, normal, and overripe) and strawberry volatiles were analyzed by gas liquid chromatography (GLC) using on-column entrainment of headspace volatiles in aqueous extracts. Computerized...

Creator:: Li, Peng, 1961-
Abstract:: Growth phenology (i.e., timing of growth initiation and cessation) is important to adaptation. This study examined the extent of genetic control of bud and cambial phenology and their relationships with stem growth in pole-size Douglas-fir (ages 13 to 16 years) from 60 open-pollinated families. The availability of bud phenology data...
