| Sprouting or germination in wheat takes place as a result of the rupture of the dormancy in grain, expressed in physiological terms as the increase of α-amylases and proteases activity, which has been associated with low values of falling number. Grain sprouting has been related with high moisture and temperature at harvest and it is a serious problem in the north of Argentina. The objectives of this study were to characterize introduced and local wheat cultivars for sprouting response through falling number and, tentatively, to identify adapted materials with good behavior for this trait. A set of thirty introduced and local late and early heading wheat varieties was tested through falling number in two experiments conducted at Marcos Juárez,... |

| The aim of this work was to obtain haploid plants of bread wheat through wide hybridization with maize. The experimental material included ten bread wheat hybrids (female parent) and one population of maize (pollen donor). Two assays were carried out in two different seasons (summer and winter). Wheat spikes were manually emasculated, each spike was pollinated twice with fresh pollen of maize and a solution of 2,4-D (100 mg l-1) was sprayed on pollinated florets and injected in the upper internode. Fifteen and 21 days after pollination caryopses were removed and surface sterilized. Embryos were cultured in tubes containing B5 medium. The ten hybrid combinations produced caryopses, but only eight of these hybrids produced embryos and, in six of them, the... |
