The results showed that there were significant varietal differences in plant biomass, yield, P efficiency and P acquisition efficiency among the 8 tested soybean varieties.
试验表明：生物学产量、经济学产量、总体磷效率和磷吸收效率具有显著的品种差异。
The families with great P efficiency have great height growth rate, high productivity and extensive lateral root system under low phosphorus stress and low sensitivity to phosphorus supply.
磷效率高的家系具有在低磷胁迫下苗高生长量大、干物质积累能力强、须侧根发达及对磷肥投入敏感性低等特点。
Genotypic differences of phosphorus(P) efficiency among 194 Brassica napus L. cultivars were investigated under pot culture in acid soil with a method of two step screening typical cultivars.
采用两步筛选法（即苗期干物质筛选和全生育期产量筛选）在酸性黄棕壤上对194个甘蓝型油菜品种进行了磷效率的筛选。
Relative yield and harvest coefficient of P-efficiency variety were higher than those of P-inefficiency variety.
磷高效基因型相对荚果产量和收获系数高于磷低效基因型。
