GENERAL AND SPECIFIC COMBINING ABILITY IN SEVEN INBRED STRAWBERRY LINES
Canadian Journal of Genetics and Cytology, 1968Seedlings 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, 1975A 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.

STUDY OF WINTER RYE SAMPLES BY GENERAL COMBINATIONAL ABILITY
PROBLEMS OF SOIL FERTILITY IN MODERN AGRICULTUREThe purpose of the study is to isolate samples of winter rye with high overall combining ability to create a new synthetic population. The research was carried out in 2018 – 2021 on the experimental fields of the Krasnoyarsk Research Institute of Agriculture.

General Combining Ability Model for Genomewide Selection in a Biparental Cross
Crop Science, 2014ABSTRACTGenomewide 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

General combining ability and its repeatability in early generations of potato breeding programmes
Potato Research, 1998General combining ability and its repeatability in the early generations of a potato breeding programme was studied by evaluating 72 progenies (18×4) of 22 parents in a factorial mating design for three successive generations. The mean squares for combining ability due to females, males and females × males were significant for eight out of the ten ...

Theoretical value of estimates of general combining ability in the autotetraploid crop
Theoretical and Applied Genetics, 1987The means of half-sib progenies have been indicated as selection criteria for intra-population improvement while the average of the means of full-sib progenies in diallel analyses have been proposed as predictors, in part, of the means of untested synthetic varieties. When these measures based on progeny means are expressed as deviations from a defined

Two-locus theory in recurrent selection for general combining ability in maize
Theoretical and Applied Genetics, 1982Two-locus theory for recurrent selection for general combining ability in maize was developed. The theory featured: (a) recombination of the selfed progeny of selected parents; and (b) linkage disequilibrium in the initial gametic array. The theory indicated: (a) that initial linkage disequilibrium exerts a permanent influence upon selection progress; (

Combining ability analysis over F1-F5 generations in diallel crosses of bread wheat
Theoretical and Applied Genetics, 1979Combining ability studies for grain yield and its primary component traits in diallel crosses involving seven diverse wheat cultivars of bread wheat (Triticum aestivum L.) over generations F1-F5 are reported. The general and specific combining ability variances were significant in all generations for all the traits except specific combining ability ...

The American Naturalist, 1983
The common assumption that species coexistence in nature can be generally explained by processes of natural selection for niche differentiation does not have strong empirical support for plants. The meaning of competitive ability has traditionally been embedded within an Eltonian view of the niche.

Journal of Oilseeds Research, 2019
Twenty four hybrids along with ten parents and four standard checks were evaluated in a Randomized block design with two replications at Regional Agricultural Research Station, Nandyal during rabi, 2018-19. The analysis exhibited significant differences among lines for ten traits and testers for nine traits.
