Giberellic acid in nutritive soluction as a height evaluation test in hexaploid wheat

Six hexaploid wheat genotypes with known height and giberellic acid sensibility, were used in a new method to test plant stature ('rht' genes) with giberellic acid nutritive solution. The plants were submitted to three periods of giberellic acid action: without giberellic acid, giberellic acid from 8th day after sowing (7 days) and giberellic acid just after sowing (15 days). The use of giberellic acid was efficient on selecting genotypes with different plant heights in all periods with giberellic tested.

Triticum aestivum L.; giberellic acid; early generadon selection
