The DP‐305423‐1 transgene elevates oleic acid concentration and reduces polyunsaturated fatty acids in soybean [Glycine max (L.) Merr.] oil, resulting in increased oxidative stability. The objective of this research was to investigate the effect of the DP‐305423‐1 transgene on agronomic and seed traits using four backcross derived soybean populations to provide further understanding of the transgene's influence across varying genetic backgrounds and environments. An equal number of high‐oleic, low‐linolenic (HOLL) and normal‐oleic, low‐linolenic (NOLL) progeny from four BC₁F₄:F₆ populations—B (n = 30), C (n = 22), D (n = 56), and E (n = 34)—were grown across six locations in 2015. Across all locations, the high‐oleic (HO) progeny had a mean yield 77 kg ha⁻¹ less in Population B, and 382 kg ha⁻¹ greater in Population C compared with the normal‐oleic (NO) class. There was no significant difference in yield between HO and NO in Populations D and E. The HO progeny had a significantly lower mean oil concentration and greater protein concentration than the NO class in all populations, whereas 100‐seed weight of the HO class was, on average, greater than in the NO class. The results provide evidence that the reduction in oil concentration is associated with the HO phenotype in the progeny carrying the DP‐3054231‐1 transgene and demonstrate no consistent effect of the transgene on seed yield, suggesting that differences may be due to the genetic background of the population studied.

四个回交群体中含有DP-305423-1转基因的高油酸大豆品系的农艺和种子性状

的DP-305423-1的转基因升高油酸浓度和大豆降低多不饱和脂肪酸[大豆（L.）MERR。]油，导致增加的氧化稳定性。这项研究的目的是使用四个回交衍生的大豆种群研究DP‐305423-1转基因对农艺和种子性状的影响，以进一步了解转基因在不同遗传背景和环境中的影响。来自四个BC ₁ F ₄：F ₆种群的相等数量的高油酸，低亚麻酸（HOLL）和正油酸，低亚麻酸（NOLL）后代-B（n  = 30），C（n  = 22） ，D（n  = 56）和E（n = 34）— 2015年在六个地点均有生长。在所有地点，高油酸（HO）后代的B族平均单产减少77 kg ha ^-1，而382 kg ha ^-1与普通油性（NO）类相比，人群C中的含量更高。在种群D和种群E中，HO和NO的产量没有显着差异。在所有种群中，HO子代的平均油浓度和蛋白质浓度均明显高于NO类别，而HO类别的100粒重为平均而言，比NO类要大。结果提供了证据，表明油浓度的降低与携带DP-3054231-1转基因的后代中的HO表型有关，并且证明了转基因对种子产量没有一致的影响，这表明差异可能是由于遗传背景所致。研究的人口。
