Studies on the methodology of crossing and selfing in Lolium multiflorum

Creator:: Bergman, Jerald Wilmer
Abstract:: Studies were conducted to determine the effectiveness of a biological pollen barrier of rye, Secale cereale, in preventing out-crossing between Lolium multiflorum genotypes in each of the 300 crossing blocks established in this experiment. Fluorescent tests of seeds of open-pollinated and single-crossed progeny of four annual ryegrass sources were used...

An evaluation of creeping habit in various progenies of red fescue (Festuca rubra L.)

Creator:: Kim, Dal Ung
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...

The examination of seed yield potential in certain genotypes of birdsfoot trefoil (Lotus corniculatus L.)

Creator:: Bresciani, Juan Carlos
Abstract:: In the last 30 years, birdsfoot trefoil (Lotus corniculatus L. ) has been recognized as a great potential source of forage. Since the 1930's, many studies have been reported in relation to birdsfoot trefoil characteristics, including some directly related with the association between seed yield and its components. The purpose...

Genetic variation and interrelationships of acid detergent fiber, neutral detergent fiber, hemicellulose, crude protein and in vitro dry matter digestibility in tall fescue (Festuca arundinacea Schreb)

Creator:: Soh, Aik-chin
Abstract:: Six parent clones and their 15 single-crosses of tall fescue (Festuca arundinaceae, Schreb) were row-planted in Corvallis, Oregon, row and sward-planted in Columbia, Missouri, and evaluated for genetic variability, genotyp-eenvironment interactions and interrelationships in acid detergent fiber (ADF), neutral detergent fiber (NDF), hemicellulose (HCL), crude protein (CP) and in vitro...

Evaluation of methods of progeny testing in tall fescue seed production (Festuca arundinacea, Schreb.)

Creator:: Thomas, Johnny Ray
Abstract:: Seventeen parental clones were selected, from 9,000 plants, on the basis of self-sterility, seed and forage yield potential using phenotypic ratings, crude protein and chromogen content. The parental clones were divided into two populations based on date of maturity. Group I was intermediate in maturity and had nine parental clones,...

An examination of seedling vigor and the effects of genetic diversity on response to heterosis in tall fescue (Festuca arundinacea Schreb.)

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...

Heritability for perloline, nitrogen, and digestibility characteristics in tall fescue (Festuca arundinacea, Schreb.) single-crosses grown in two locations

Creator:: Watson, Clarence Ellis
Abstract:: Tall fescue often results in poor liveweight gains. This may be accounted for by variations in perloline content, nitrogen content, or digestibility of the plant. Two groups of tall fescue plants were examined for each of these traits. These groups consisted of (a) fifteen single-crosses of a six parent diallel...

Temperature x genotype effects for perloline, crude protein and total water soluble carbohydrate levels in tall fescue (Festuca arundinacea, Schreb.)

Creator:: Beuselinck, Paul Richard
Abstract:: Perloline levels have been associated with poor animal performance on tall fescue pastures. Animal performance is low when perloline levels are high. High perloline levels are reported during hot, dry weather and increased N fertilization. Tall fescue perloline levels appear to be affected by genetic and environmental differences. Positive associations...
