摘要

大豆是一种具有重要战略意义的农作物,是植物脂肪和蛋白质的来源。从大豆中提取的加工产品被用于食品、牲畜和其他各种行业。为了扩大俄罗斯的大豆生产,必须开发适应北纬地区农业气候条件的品种,包括西西伯利亚,其特点是生长季节相对较短,日照时间较长。研究E1、E2、E3和E4基因对大豆光周期响应的影响及其对植物发育时机的影响,是有效培育适应性早花早熟大豆品种的必要条件。分析了鄂木斯克农业科学中心收集的102个品种,包括该中心的原始品种、国内其他育种中心的品种以及来自波兰、瑞典、白俄罗斯、乌克兰、加拿大等国的国外品种和育种材料。花期数据是在2021年至2023年期间在鄂木斯克州进行的一项田间试验中收集的。采用经典PCR标记和基于竞争等位基因特异性PCR的下一代标记进行基因分型。结果表明,E位点的隐性等位基因(e1-as、e1-fs、e2-ns、e3-tr、e3-fs、e4-kes、e4-kes+e4-SORE-1)为光周期中性表型。E2和E4位点对开花日期的影响最大,而E3位点对开花结束日期和总花期的影响最大。研究结果可用于西伯利亚生态型早花品种的标记辅助选择。

Analysis of the Allelic Structure of Photoperiodism Genes E1–E4 in Soybean Collections and Its Impact on the Timing and Duration of Flowering under the Growing Conditions of the Omsk Oblast

Soybean is a strategically important agricultural crop that serves as a source of vegetable fat and protein. The processed products derived from soybean are utilized in the food, livestock, and various other industries. To expand soybean production in Russia, it is essential to develop varieties that are adapted to the agroclimatic conditions of northern latitudes, including Western Siberia, which is characterized by a relatively short growing season and long daylight period. To effectively develop adaptive early-flowering and early-maturing soybean varieties, it is essential to evaluate the impact of the E1, E2, E3, and E4 genes on the photoperiodic response of soybean and their influence on plant development timing under local conditions. A total of 102 accessions from the Omsk Agricultural Scientific Center’s collection were analyzed, including original varieties from the center, varieties from other domestic breeding centers, and foreign varieties and breeding accessions from Poland, Sweden, Belarus, Ukraine, Canada, and other countries. Data on flowering dates were collected from a field experiment conducted in the Omsk oblast between 2021 and 2023. Genotyping was performed using both classical PCR-based markers and next-generation markers based on competitive allele-specific PCR. The analysis revealed that the recessive alleles of the E loci, which produce a photoperiodically neutral phenotype (e1-as, e1-fs, e2-ns, e3-tr, e3-fs, e4-kes, e4-kes+e4-SORE-1), are predominant in the collection. Furthermore, it was determined that the E2 and E4 loci exert the most significant influence on the full flowering date, while the E3 locus has the greatest effect on the end date of flowering and the overall duration of flowering. The findings can be utilized in marker-assisted selection to develop early-flowering varieties of the Siberian ecotype.
