摘 要:江西省春大豆主要种植于红壤丘陵旱地,有效磷含量低严重制约了江西省春大豆生产,选育磷高效春大豆品种有助于促进江西省春大豆生产发展。本研究采用低磷胁迫与正常供磷盆栽试验,以净光合速率、生物量、磷吸收效率、磷利用效率和磷浓度等12个性状为指标,结合主成分和隶属函数分析对17份江西省选育的春大豆品种及其骨干亲本的磷效率进行评价。研究发现不同大豆品种之间在净光合速率、磷吸收效率和磷利用效率等12个性状指标上存在显著差异。在供试材料中,国外资源巴西11的综合磷效率最高,黑农35最低,而利用巴西11拓宽遗传基础选育的春大豆新品种赣豆10号、赣豆11号和赣豆12号与江西省选育的其他春大豆品种相比,综合磷效率高、对低磷胁迫也具有更好的耐受性,提高了江西省春大豆品种对低磷胁迫的耐受水平,有助于促进江西省春大豆产业发展。Spring-sowing soybean in Jiangxi province of China is mainly planted in the red hilly soil region,where low phosphorous availability restricts the yield production. Breeding for spring soybean cultivars showing high phosphorous use efficiency will hence become of interest to ensure its production in Jiangxi province. To understand the phosphorous efficiency of spring soybean cultivars and their foundation parents,12 traits(i.e. net photosynthetic rate,biomass,phosphorous absorption efficiency,phosphorous use efficiency,and phosphorous concentration) were evaluated under normal and low phosphorous soil pot conditions,followed by the analysis of the principal component and associated membership functions. There were significant differences in 12 traits including net photosynthetic rate,phosphorus absorption efficiency and phosphorus use efficiency among 17 soybean cultivars. Gained from the comprehensive analysis,the cultivar Brazil 11 was qualified as a high-efficiency phosphorous germplasm,whereas Heinong 35 was a low-efficiency phosphorous germplasm. Moreover,the phosphorous efficiency of cultivars Gandou 10,Gandou 11 and Gandou 12 derived from the parental cultivar Brazil 11 was higher than that of other soybean cultivars in Jiangxi,showing higher tolerance under low phosphorous stress condition. These spring soybean cultivars significantly enhanced the tolerance to low phosphorus stress,and thus became important to promote the development of spring soybean in Jiangxi province.
