| D.purpurea is grown in cold areas with long days. In the Buenos Aires province market it is absent, probably because it is a complicated and expensive crop. The horticultural growers prefer the imported costly hybrid seed because plants flower without suplementary light or cold. The objectives of the experiments which were laid out were to find, among the individuals of a population grown wild, genotypes that responded to the Buenos Aires conditions, producing plants induced in pots and assesing if there was response to natural aggregates. Seed harvested in Bariloche was sown on the 29/05/o4. The plants were transplanted to 3 liter pots. 30 pots were placed in greenhouse and treated with chemical fertilization. 54 pots were placed outdoors in the sun and... |

| Flowering time in bread wheat (Triticum aestivum L.) is controlled by vernalization and photoperiod response, and earliness per se genes. The genetic basis of flowering time has not been investigated in Pakistani bread wheat. This study was, therefore, conducted to determine the allelic composition at Vrn-A1, Vrn-B1, Vrn-D1, Vrn-B3 and Ppd-D1a loci of 59 Pakistani spring bread wheat cultivars. These cultivars, along with 4 isogenic lines for vernalization genes were characterized with previously reported DNA markers designed for detecting allelic variation at 4 Vrn (Vernalization) and 1 Ppd (Photoperiod) loci. Spring habit Vrn-A1a allele was found in 36% cultivars either alone or with spring habit Vrn-B1 and Vrn-D1 alleles. Two wheat cultivars had the... |

| In cereals, the transition from the vegetative stage to flowering is controlled in the main by the set of vernalization genes. Within these genes the most important role is played by VRN1, which encodes a MADS-box transcription factor, regulating the transition of shoot apical meristem to the reproductive phase. The level of vernalization requirement is strongly linked to the molecular structure of this gene. In this study we analyzed molecular mechanisms regulating the vernalization requirement in triticale on the basis of comparative analysis of the VRN1 locus between triticale (×Triticosecale Witt.) and common wheat (Triticum aestivum L.) genotypes. We also estimated the influence of VRN genotype on heading time and the winter hardiness of these two... |
