General Combining Ability Model for Genomewide Selection in a Biparental Cross [PDF]

open access: possibleCrop Science, 2014
ABSTRACTGenomewide selection within an A/B biparental cross is most advantageous if it could be effectively done before the cross is phenotyped. Our objectives were to determine if a general combining ability (GCA) model is useful for genomewide selection in an A/B cross, and to assess the influence of training population size (NGCA), number of crosses

Specific and general combining ability for yield in potatoes

American Potato Journal, 1962
Forty-five lines were crossed to six testers to evaluate their general combining ability. These lines did not clearly represent a random selection of lines with respect to this character, though they had not undergone any formal selection in this respect.

Relevance of Specific versus General Combining Ability in Winter Wheat

Crop Science, 2012
ABSTRACTKnowledge of quantitative genetic parameters is crucial in allocating resources for different steps of multistage selection programs. The main objective of the present study was to investigate the magnitude of variance of general combining ability (GCA) and specific combining ability (SCA) effects and their interaction with environments in ...

Parental generation in relation to combining ability analysis in spring barley

Theoretical and Applied Genetics, 1974
A comparison between Griffing's (1956) Method 1, Model I, and Method 3, Model I, using data from a 10 × 10 diallel of spring barley grown in eight different environments, revealed that inclusion of the parental generation (Method 1) caused considerable upward bias in the estimates of both the general and specific combining ability variances, whereas ...

GENERAL AND SPECIFIC COMBINING ABILITY IN SEVEN INBRED STRAWBERRY LINES [PDF]

open access: possibleCanadian Journal of Genetics and Cytology, 1968
Seedlings of a diallel cross of seven strawberry inbreds omitting reciprocals were fruited in matted rows. Per acre fruit yields were comparable with leading cultivars, but berry appearance and quality of the hybrids were poor. Differences in resistance to powdery mildew reflected the values of the cultivars from which the inbreds were derived.All ...

General and specific combining abilities for different economic traits in broiler chickens

Theoretical and Applied Genetics, 1975
A complete diallel cross of four broiler breeds was made to investigate whether there are breed differences in the combining abilities for the traits, body weight, weight gain and feed efficiency, measured during the growing period from 4 to 12 weeks of age. Data collected from male and female birds were analysed separately.

ESTIMATION OF GENERAL AND SPECIFIC COMBINING ABILITIES IN POTATO

Canadian Journal of Genetics and Cytology, 1976
Seven quantitative traits of the cultivated potato (Solanum tuberosum L.) were studied in a partial diallel cross experiment. Large specific combining ability effects were observed for total and marketable yields, total number of tubers, and number of marketable tubers. Large general combining ability effects were obtained for average weight per tuber,
