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

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.

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.

Generation of dihaploids and molecular analysis of general combining ability, strategies for a sustainable plant breeding

Agro-Divulgación, 2023
Resumen El mejoramiento genético convencional de diversas especies requiere de la formación y evaluación de líneas, híbridos y testigos en extensos experimentos de campo, por varios ciclos y a través de diferentes ambientes. Tales procesos originan factores que causan afectación a los recursos naturales y/o daños a la salud del ser humano.

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.

Combining Ability Analysis in Rice (Oryza sativa L.)

International Journal of Pure & Applied Bioscience, 2019
Combining ability in rice was studied with a set of 4 lines and 10 testers and their 40 hybrids. The magnitudes of gea variances were higher than sea variances for all the characters which indicated that additive gene action was predominant in the ...

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; (
