“…A mapping population of 150 F 4:8 RILs derived from a cross between two Andean parents Solwezi and AO‐1012‐29‐3‐3A (AO) was studied. This mapping population was derived using single seed descent method (Kamfwa, Beaver, Cichy, & Kelly, 2018; Kamfwa, Cichy, & Kelly, 2019). Solwezi is a Zambian landrace, with a type IV growth habit (climber) and red‐mottled seed type, and is widely grown in Zambia.…”

Aluminum toxicity in acidic soils is a major constraint to common bean (Phaseolus vulgaris L.) production. The objective of this study was to identify quantitative trait loci (QTL) for Al resistance in a population of 150 F 4:8 recombinant inbred lines (RILs) derived from parents Solwezi and AO-1012-29-3-3A, which contrasted in resistance to Al. The RILs and their parents were evaluated for Al resistance in a hydroponic system that had two nutrient solutions with either 0 μM (control solution) or 15 μM Al concentration (Al stress solution). Primary traits including root length (RL), root dry weight (RDW), and shoot dry weight (SDW) were measured. Percentage reductions in RL, RDW, and SDW were calculated from their respective primary traits. The RILs were genotyped with 5,398 single nucleotide polymorphisms and QTL identified using composite interval mapping. A total of eight QTL for Al resistance were identified on chromosomes Pv02, Pv04, Pv06, Pv07, Pv09, and Pv10. Variation in Al resistance explained by individual QTL ranged from 7.6 to 14.7%. Aluminum resistance QTL RL10.1 on Pv10 explained 10% of the genetic variation in RL. The QTL RL10.1 overlapped with QTL RDW10.1 identified for RDW in Al stress solution. Another Al resistance QTL RL6.1, which explained 10% of Al resistance variation, was identified on Pv06. The QTL on Pv02 and Pv07 appear to overlap with previously reported QTL for Al resistance. A candidate gene Phvul.007G025900 encoding an Al-activated malate transporter was identified within the QTL RL7.1 The genetic architecture of Al resistance in the Solwezi and AO-1012-29-3-3A population is polygenic with additive action.Abbreviations: LOD, logarithm of odds; QTL, quantitative trait locus/loci; RDW, root dry weight; RIL, recombinant inbred line; RL, root length; SDW, shoot dry weight; SNP, single nucleotide polymorphism.

“…Regarding thrips resistance (Thrips palmi Karny), only a QTL named as Tpr6.1 located on Lg b06 was determined by Frei et al [114]. Concerning the bean weevil (Acanthoscelides obtectus [Say]) which is a crucial postharvest pest of common bean seed Kamfwa et al [115], discovered three QTLs on chromosomes Pv04 and on Pv06. In addition to these QTLs examples related to biotic stress factors, several QTL studies were also released about abiotic stress factors.…”

“…The low frequency of F 4 lines with high levels of resistance to weevils suggested that the complex APA locus is not the only factor associated with resistance to the common bean weevil. This information was confirmed by Kamfwa et al (2018) who identified three QTL for resistance to A. obtectus on Pv04 and on Pv06. One of the QTL on Pv04 was previously reported as the APA resistance locus while the other two QTL were new.…”

Most literature reviews focus on a specific topic. The purpose of this paper, however, is to review the contributions made by a multidisciplinary team of researchers at a specific location (Puerto Rico) over a period of several decades. This paper documents bean research of the University of Puerto Rico and the USDA-ARS Tropical Agriculture Research Station during the past century. The following illustrates the merits of continuity of effort in research and shows that research often follows a logical sequence of actions to solve problems related to genetic improvement as well as to study biotic and abiotic factors that affect common bean production in Central America and the Caribbean. Finally, this narrative demonstrates that the ongoing development of improved bean germplasm lines and cultivars is cyclical and builds upon previous research achievements. IntRodUctIon The common bean (Phaseolus vulgaris L.) is an important component of the traditional diet in Puerto Rico. The 1900 report of the USDA Puerto Rico Agricultural Experiment Station (USDA-PRAES) noted that rice and beans were staple crops in Puerto Rico and found on the tables of both the rich and poor. Smit et al. (2007) noted that annual per capita consumption of grain legumes, mostly dry beans, in
