Conteúdo: |
A selection of drought tolerant genotypes of sunflower was attempted. Starting from an interspecific cross with H. argophyllus, four cycles of divergent selection on a physiological criteria in relation with the cuticular transpiration of leaf (the Relative Water Loss) allow the production of two contrasted genotype: T- (low level of leaf cuticular transpiration) and T+ (high level leaf cuticular transpiration). Field experiments show better yield tolerance index combined with good potential yield for T- hybrids in some location. Physiological analysis done in the in field and in controlled conditions allow to distinguish the two genotypes for only one parameters: the osmotic adjustment. Molecular comparison revealed the existence of a DNA differentiating T- from T+. This cDNA has high homology with a amino-acid transporter. A quantification of the amino-acid concentrations during water deficit in T- and T+ lines, show that the T- plant accumulate significantly more proline than T+ ones. RFLP and STS analysis using this cDNA allow to differentiate the two lines. |
