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.

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.

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 ...

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; (

USING GENERAL AND SPECIFIC COMBINING ABILITY TO FURTHER ADVANCE STRAWBERRY (FRAGARIA SP.) BREEDING

Acta Horticulturae, 2014
Strawberry is one of the five fruit crops included in the USDA-funded multi-institutional and trans-disciplinary project, “RosBREED: Enabling Marker-Assisted Breeding in Rosaceae”. A Crop Reference Set (CRS) was developed of 900 genotypes and seedlings from 40 crosses representing the breadth of relevant diversity and encompassing founders used in ...

GENERAL AND SPECIFIC COMBINING ABILITY IN SEVEN INBRED STRAWBERRY LINES

Canadian 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 ...

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 ...

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.
