The original Brazilian base population Composto Amplo (CA) and a population (4CA) from the 4th cycle of selection from it for Al tolerance on an acid Brazilian Oxisol soil were compared with the population Hays Golden, Nebraska B Synthetic, Corn Belt X Brazilian and Corn Belt X Caribbean when grown in nutrient solutions containing 241 umol Al/litre Root length was slightly greater in CA than in 4CA and both had considerably longer roots than the other populations. The selection of CA for Al tolerance decreased the frequency of the most tolerant plants in favour of plants of intermediate tolerance. The CA and 4CA populations had a higher frequency of genes for Al tolerance than the other populations. The Corn Belt X Brazilian population consistently ranked higher in Al tolerance than Hays Golden and Nebrasla B synthetic, indicating that the introgression of Brazilian germplasm increased tolerance. CA and 4CA roots had lower Al concentrations, but similar Al contents to those of Hays Golden and Nebraska B Synthetic. Other differences in element concentrations and contents between the 2 sets of populations were observed, while the hybrid populations were intermediate between their tropical and temperate parental populations for these factors. |
