Multilocational trials were conducted in several agroecological zones in West Africa to assess the magnitude of genotype x environment (G XE) interaction and to identify stable varieties which could be used in breeding programs in the region. The reaction of the varieties to major cassava diseases and pests was also assessed. Ten clones, including 7 IITA improved cassava clones, were used in the study. Results from 22 trials condusted in a randomized complete block design revealed a highly significant G X E interaction for fresh root yield, African cassava mosiac virus, cassava bacterial blight, cassava green mite, and cassava mosiac. TMS 30572, TMS 63397, TMS 91934, and TMS 50395 were the most adaptable cultivars. TMS 30572 was the most stable of them. Somecountries had cultivars adaptable to specific local environments. |

Conteúdo: |
Aiming to contribute to the development and improvement of modern soil mapping techniques, an analysis of the basic concepts and practices adopted by the Digital Soil Mapping was performed, under the focus of pedological knowledge. The main deficiencies and inconsistencies concerning the Scorpan model and the conceptual approach of the method are identified and discussed. Some problems related to the soil maps produced are also pointed out. The importance of pedological knowledge for the development of soil mapping techniques and soil interpretation is emphasized, which in the authors' opinion should receive special attention from the scientific community dedicated to the topic. |
