Development of Al‐tolerant cultivars may be a cost effective response to the problem. In previous investigations, we identified an Al‐tolerant soybean [Glycine max (L.) Merr.] plant introduction from Japan (PI 416937), and subsequently determined the heritability of the trait in a cross with Young, a highly productive Al‐sensitive cultivar. The objective of the present study was to identify quantitative trait loci (QTL) which condition Al tolerance by a genetic linkage map of 155 restriction fragment length polymorphism (RFLP) marker loci and a hydroponics‐based Al response. The 120 F4‐derived progeny from Young × PI 416937 were divided into four sets and evaluated with the parents for tap root extension in 0 and 2 μM Al3+ activity solutions (NOAL and HIAL, respectively) employing Al levels as whole plots in a split‐plot experimental design. Aluminum tolerance was defined as (i) root extension under HIAL conditions, and (ii) root extension as a percentage of control [PC = (HIAL/NOAL) × 100]. Multiple regression analysis revealed five QTL from independent linkage groups which conditioned root extension under HIAL stress. Three of the five QTL were also detected by PC as the expression of Al tolerance. While most alleles for Al tolerance were derived from the Al‐tolerant parent, PI 416937, a RFLP allele from Young (for marker EV2‐1) improved Al tolerance expressed as PC and exhibited a similar trend under HIAL stress. At present, it is not known whether the Al tolerance gene from Young, in combination with those from PI 416937, will raise Al tolerance beyond that now observed in the PI. One allele for Al tolerance from PI 416937 (for marker B122‐1) may be difficult to capitalize upon, agronomically, because of its association with a detrimental pod dehiscence factor. Further experimentation is needed to distinguish between linkage and pleiotropic effects near this marker. A favorable epistatic effect for Al tolerance was detected between two alleles from the PI 416937. The relationships revealed by marker analysis indicated that marker‐facilitated selection may be a viable approach in the breeding of Al‐tolerant soybean.}, number={2}, journal={CROP SCIENCE}, author={Bianchi-Hall, CM and Carter, TE and Bailey, MA and Mian, MAR and Rufty, TW and Ashley, DA and Boerma, HR and Arellano, C and Hussey, RS and Parrott, WA}, year={2000}, pages={538–545} }

Merr.] yield in many growing areas. When correction of toxicity by management is impractical, an economically sound alternative is to develop Al tolerant cultivars. Heritability (h 2 ) estimates for Al tolerance in hydroponics would aid in the efficient design of selection programs for cultivar development. Our objectives were to determine the h 2 of Al tolerance in a F 4 -derived population using tap root extension in hydroponics culture as the indicator of tolerance. The 120 random F 4 -derived lines of sensitive 'Young' x tolerant PI 416937 were evaluated in the absence (NOAL) and presence (HIAL) of Al (2 μM Al 3+ activity) by means of a split-plot design. Aluminum stress increased seedling tap root extension 3% in PI 416937 and decreased extension in Young 53%. Mean progeny performance decreased 31%. Analysis of variance revealed significant (P < 0.05) progeny and progeny x Al interaction effects, indicating heritable genetic variation for Al tolerance. The h 2 under HIAL was moderate (0.57) on a single-replication basis and high (0.87) based upon five replicates, indicating the relative ease by which Al tolerance may be improved. Tolerance expressed as percent of control (PC) had a similar h 2 . Approximately 6% of the F 4 -derived progeny in this study were numerically similar to the parents for Al response under HIAL, suggesting that three to five genes may control Al tolerance and that a population size of 150 random inbred lines may be needed to assure full recovery of Al tolerance in the progeny of future breeding populations. Expected gain and risk avoidance analysis suggested that two or three replications are sufficient for initial screening of single seed descent (SSD) populations derived from the PI 416937 and that employment of this PI as a control enhances the ability of the breeder to discard inferior types during screening. Practical advice is presented to assist plant breeders in the efficient improvement of Al tolerance in soybean.}, number={2}, journal={CROP SCIENCE}, author={Bianchi-Hall, CM and Carter, TE and Rufty, TW and Arellano, C and Boerma, HR and Ashley, DA and Burton, JW}, year={1998}, pages={513–522} }
