A historical review of research and development related to the identification, utilization and economic impact of maize germplasm adapted to acid soils a EMBRAPA/CNPMS is presented. Methods to identify tolerant germplasm and to select segregation materials, through field experiments in acid and fertile soils and screening in nutrient solution are discussed. Results of research including inheritance for aluminum tolerance and development of high yielding tolerant hybrds are presented. Also, results of phosphorus efficiency related to root development of high yielding tolerant hybrids are presented. Also, results of phosphorus efficiency related to root development, internal accumulation of P and kinetics of absorption of P and N are discussed. The experience accumulated in this research program has shown that adaptation to acid soils can be associated, in the same genotype with high yield potential and yield stability, as a result of tolerance to Al toxicity and improved P use efficiency. This program has generated several commercial cultivars which have been successfully utilized in a large area of Brazil. The knowledge and experimental germplasm generated are also valuable resources which are being used to support basic studies of mechanisms of tolerance to aluminum and nutrient use efficiency. A better understanding of these mechanisms will help the development of better strategies for selection and improved cultivars in the future. |

The common New World egg parasitoid of the corn leafhopper Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae), an economically important pest of maize from Argentina to southern USA, has long been misidentified as the Palaearctic species Anagrus incarnatus Haliday or its synonym A. breviphragma Soyka (Hymenoptera: Mymaridae). Using a combination of genetic and morphometric methods, and available biological information, specimens reared from eggs of D. maidis in Argentina and Mexico, described and illustrated here as Anagrus ) virlai Triapitsyn sp. n., are shown to be different from those of A. incarnatus from the Palaearctic region. Mitochondrial and nuclear ribosomal DNA sequence data provide clear evidence for the separation of the two species. Anagrus virlai is also known from Brazil, Colombia, Guadeloupe (France), and Guyana. |
