Abstract
Hybrids with heterotic effects manifest themselves with a significant enhancement in growth and productivity traits compared with their parental genotypes. However, inbreeding resulted in decreased heterosis. Researchers believe that a noteworthy increase in F1 hybrids for economic and biological attributes is evident due to heterozygosity and overdominance of the corresponding genes of different parents combined in one genotype. The presented study sought to determine the heterotic effects of sugar beet hybrids for economically valuable traits and select the best parental lines with crossing potential for productivity. Five different sugar beet hybrids, analyzed during the crop seasons 2021 and 2022 for accurate and hypothetical heterosis and the degree of dominance in F1 generation for economically valuable traits like productivity and sugar content, transpired at the LLP – Kazakh Research Institute of Agriculture and Plant Growing (KazRIAPG), Kazakhstan. The crossing of the sugar beet line KazMS with pollinators, viz., VP24, VP44, OP17231, OP17232, and OP14044, changed the type of inheritance in hybrids for productivity from negative dominance in variants with pollinators (VP24, OP17231) to overdominance in variants with pollinators (VP44, OP14044). Based on the results, the conclusion indicated that the type of productivity inheritance in F1 hybrids involving the same maternal line differed.
期刊介绍:
The SABRAO Journal of Breeding and Genetics is an international journal of plant breeding and genetics research and was first published in 1969. It is the official publication of the Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO).
Its objectives are to: promote the international exchange of research information on plant breeding and genetics, by describing new research findings, or ideas of a basic or practical nature; and be a medium for the exchange of ideas and news regarding members of the Society.
The Journal gives priority to articles that are of direct relevance to plant breeders and with emphasis on the Asian region. Invited for publication are research articles, short communications, methods, reviews, commentaries, and opinion articles. Scientific contributions are refereed and edited to international standards.
The journal publishes articles for SABRAO members mainly. The Journal preferred strongly that at least one author should be a current member of the Society. Non-members may also publish in the journal.
