Conteúdo: |
The objective of this work was to evaluate hybrids of Brachiaria decumbens for root vigor and aluminum resistance as components of edaphic adaptation. One hundred intraspecific hybrids and their parents were evaluated in a greenhouse solution-culture. Significant differences for both traits indicate that there is genetic variability amongst hybrids. The parents had a similar performance for root growth, but differed significantly for aluminum resistance. Twenty three and seven hybrids were superior to cv. Basilisk for root vigor and aluminum resistance, respectively, but most of them were not coincident for both traits. Aluminum resistance seemed to vary quantitatively, since the majority of the hybrids were placed around the mean and fewer in the extremes. The estimate of heritability based on progeny means for aluminum resistance (0.27) was lower than for root vigor (0.69). The method used was efficient in discriminating hybrids, and identified the best ones for edaphic adaptation. |
