STUDY OF WINTER RYE SAMPLES BY GENERAL COMBINATIONAL ABILITY

PROBLEMS OF SOIL FERTILITY IN MODERN AGRICULTURE
The 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, 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

Theoretical value of estimates of general combining ability in the autotetraploid crop

Theoretical and Applied Genetics, 1987
The 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, 1982
Two-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, 1979
Combining 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 ...

Ecological Combining Ability and Competitive Combining Ability in Plants: Toward a General Evolutionary Theory of Coexistence in Systems of Competition

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.

General combining ability of parents and specific combining ability of crosses for yield and oil related traits in sunflower (Helianthus annuus L.)

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.

Generating New Business Ideas: The Ability of Category Combination and Reorganization

SSRN Electronic Journal, 2009
Many scholars argue that from a cognitive perspective the creative act of opportunity recognition can be conceptualized as a transformation process of bringing together previously unrelated knowledge in order to create a new means-ends framework. Along these lines, the present paper empirically investigates whether the basic cognitive process of ...
