土壤酸度和氮磷有效性低是湿热带强风化土壤中菜豆生产的重要制约因素。本研究的目的是确定豆类品系能够产生更高的产量作为结果，更大的N和P利用效率的条件下，中间土壤N和P的可用性。适应低土壤肥力的选择可以用于植物育种计划，以提高豆类种子产量。在Oxisol试验箱中，对33个菜豆品系和来自波多黎各的品种“Morales”和“Verano”以及来自海地的品种“Salagnac 90”在三种施肥制度下的表现进行了评价。（极细、高岭土质、等温热型Eutrustox）：（i）50 kg N/ha（+N）、57 kg P2 O 5/ha（+P）、54 kg K2 O/ha（+K），（ii）-N、+P和+K，以及（iii）+N、-P和+K，在2007年6月和2008年1月的两次田间种植中。在营养非限制条件（+N +P +K）下，黑豆品系PR 0443 -151和红豆品系PR 0340 -3-31的种子产量始终较高。耐低氮品系和始终具有最高氮利用效率的品系是PR 0443 -151、VAX 3、RBF 11-33和RBF 19-63。氮素利用效率高且对施氮有反应的株系是PR 0443 -151、IBC 309-23和A774。PR 0340 -3-31、PR 0443 -151、A774和VAX 3在土壤磷限制条件下种子产量最高，表现出较高的土壤磷利用效率。在营养限制和非限制条件下具有高相对产量、高营养利用效率和对低土壤氮和磷的耐受性的豆类品系的鉴定可以帮助加勒比地区豆类生产的育种计划和最终的可持续性。(C)2010 Elsevier B.

Soil acidity and low nitrogen (N) and phosphorus (P) availability are the most important constraints for common bean (Phaseolus vulgaris L) production in highly weathered soils of the humid tropics. The objective of this study was to identify bean lines capable of producing higher yields as the result of greater N and P use efficiency under conditions of intermediate soil N and P availability. Selection for adaptation to low soil fertility can be used by plant breeding programs to improve bean seed yields. The performance of 33 bean lines and the varieties 'Morales' and 'Verano' from Puerto Rico and 'Salagnac 90' from Haiti were evaluated under three fertilization regimes in an Oxisol (very-fine, kaolinitic, isohyperthermic Typic Eutrustox): (i) 50 kg N/ha (+N), 57 kg P2O5/ha (+P), 54 kg K2O/ha (+K), (ii) -N, +P, and +K, and (iii) +N, -P and +K in two field plantings of June 2007 and January 2008. The black bean line PR0443-151 and red bean line PR0340-3-31 had consistently higher seed yields under nutrient non-limiting conditions (+N +P +K). The low N tolerant lines and those that consistently had the highest N use efficiencies were PR0443-151, VAX 3, RBF 11-33 and RBF 19-63. Lines that were both efficient in N utilization and responsive to N application were PR0443-151, IBC 309-23, and A774. PR0340-3-31, PR0443-151, A774 and VAX 3 had the highest seed yields under soil P limiting conditions and expressed high soil P use efficiency. The identification of the bean lines with high relative yields under both nutrient limiting and non-limiting conditions, high nutrient use efficiency, and tolerance to low soil N and P. can help breeding programs and eventual sustainability of bean production in the Caribbean.
