Nevertheless, through an ongoing process of selection, farmers have obtained cultivars adapted to these marginal conditions. In earlier work to collect and test maize landraces, the following collections were found to be superior: 1394, 1439 and 1452 for favorable edaphic environments, and 1393, 1439 and 1449 for marginal environments (Lopez et al., 1990). As a second step, in 1989 trials were established at two sites with the two groups of collections for the differing soil conditions, using H-28, H 220 and the farmers' landrace as checks. Although the hybrids showed better plant type than the landraces, the latter were earlier, had better ear aspect, higher grain percentage and higher grain yield per hectare. Collections 1393 and 1394 were the best performers. These results demonstrate the need to conduct genetic improvement in specific areas using the local landraces as the source material to increase yields and grain production in Mexico's rainfed areas.Collection: CIMMYT Publications Collection
