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.

甜菜(beta vulgaris l .)的杂种效应杂交的根产量和含糖量

与亲本基因型相比，具有杂种优势效应的杂交种在生长性状和生产力性状上有显著提高。然而，近交导致杂种优势降低。研究人员认为，由于不同亲本组合在一个基因型上的相应基因的杂合性和显性，F1杂交种的经济和生物学属性显著增加。本研究旨在确定甜菜杂交种对经济价值性状的杂种优势效应，并选择具有杂交生产力潜力的最佳亲本。哈萨克斯坦农业和植物生长研究所(KazRIAPG)在2021年和2022年的作物季节对5种不同的甜菜杂交品种进行了准确和假设的杂种优势分析，以及F1代在生产力和含糖量等经济价值性状上的优势程度。甜菜品系KazMS与传粉者VP24、VP44、OP17231、OP17232和OP14044的杂交，使杂种杂种的生产力遗传类型从带传粉者的负显性变异(VP24、OP17231)变为带传粉者的显性变异(VP44、OP14044)。结果表明，同一母系的F1杂交种的生产力遗传类型存在差异。

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.
