摘要

缺磷是世界各地影响绿豆生长的严重问题之一。在低磷（LP）和正磷（NP）条件下，对54个绿豆基因型的根、茎和生物量相关性状进行了研究，以鉴定其磷高效基因型。本研究以所研究性状的磷利用效率隶属函数值作为研究绿豆磷利用效率的简明指标。在所研究的性状中，LP条件下，根系总体积、叶绿素浓度、根干重和根冠比的平均值增加了25%以上，表明这些性状对缺磷具有高度响应性。相关和逐步回归分析表明，RDW解释了大部分变异，可以作为PUE的明确指标。具有高MFVP值的MH805、M42、PUSA9531、EC398885和M209 5个高效P基因型可用于改善绿豆的PUE。

Unravelling the phosphorus use efficiency associated traits in mungbean (Vigna radiata L.) under low phosphorus condition

Phosphorus (P) deficiency is one of the serious problems affecting plant growth in mungbean in different parts of the world. The root, shoot and biomass related traits were investigated for identifying P-efficient genotypes in 54 mungbean genotypes under low-P (LP) and normal-P (NP) conditions. In this study, the membership function value of P use efficiency of studied traits was used as a compendious index for studying P use efficiency (PUE) in mungbean. Among the studied traits, mean values of total root volume, chlorophyll concentration, root dry weight (RDW) and root to shoot ratio increased >25% under LP condition indicating that these traits are highly responsive to P deficiency. Correlation and stepwise regression analysis revealed that RDW explained most of the variation and could be used as a clear indicator of PUE. The five highly P-efficient genotypes namely, MH 805, M 42, PUSA 9531, EC 398885 and M 209 with high MFVP values may be used for PUE improvement in mungbean.
