摘要:

本研究建立了叶柄长度检测方法,并对EMS诱变冀黄13获得的高光效新种质M657为材料,于2017-2018年度在北方、黄淮、南方共7个地点进行表型鉴定。与冀黄13相比,M657在北方春、黄淮海夏及南方夏种植时矮化、叶柄短表型稳定,M657株高与叶柄长度显著降低,有效分枝数增加,生育期延长2-7 d,单株粒重、百粒重下降;4个短叶柄新品系的选育为大豆株型改良提供了重要的亲本种质,同时证明了利用矮杆短叶柄新种质M657理想株型为耐密、高产大豆新品种的培育的可行性


Abstract:

Phenotypic screening of soybean germplasm suitable for high planting density is currently the most viable strategy to increase yield.  Previous studies have shown that soybean varieties with dwarf features and a short petiole often exhibit a compact plant architecture which could improve yield through increased planting density, although previously reported short petiole accessions were ultimately not usable for breeding in practice.  Here, we established a method to assess petiole length and identified an elite mutant line, M657, that exhibits high photosynthetic efficiency.  The agronomic traits of M657 were evaluated under field conditions, and appeared to be stable for short petiole across seven locations in northern, Huang–Huai, and southern China from 2017 to 2018.  Compared with the Jihuang 13 wild type, the mutant M657 was shorter in both petiole length and plant height, exhibited lower total area of leaf, seed weight per plant and 100-seed weight, but had an increased number of effective branches and the growth period was prolonged by 2–7 days.  Using M657 as a parental line for crosses with four other elite lines, we obtained four lines with desirable plant architecture and yield traits, thus demonstrating the feasibility of adopting M657 in breeding programs for soybean cultivars of high density and high yield.
