This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Organizations such as the Canadian Wheat Board rely on yield forecasts to plan grain handling and marketing strategies. Therefore, a model that accurately predicts yield would be useful. In plant breeding programmes involving advanced line evaluations at different locations, lack of adequate resources may be a limitation. Differences among genotypes at different locations are due to genetic as well as environmental effects. These studies investigated the effects of temperature, photoperiod, and vernalization on the growth and development of spring wheat cultivars, and assessed the ability of the CERES-wheat model to predict yield in yield trials conducted in western Canada. Field experiments were conducted at Winnipeg and Carman, Manitoba, using three seeding dates at each location, to provide data for model calibration and validation. Controlled environment studies elucidated environmental effects which may be difficult to discern under field conditions. Da a on phenology, yield-related components, weather, and model-required soil properties were collected for all trials. High temperatures accelerated the growth of vernalization-insensitive cultivars by decreasing time to anthesis and time to maturity, and reduced the number of main stem leaves and yield-related components. High temperatures decelerated the growth of vernalizafion-sensitive cultivars and prolonged the length of the vegetative growth period. Differential cultivar phyllochron responses to temperature increases were evident. Therefore, the use of modified thermal time calculations in the CERES-wheat model may not be appropriate for all genotypes. To reduce errors in phyllochron interval calculations, crop modellers may need new equations to address temperature sensitivity of cultivars. Cultivar differences in time to heading, anthesis, and maturity, were attributable to differences in the time to terminal spikelet initiation. The CERES-wheat model was sensitive to changes in seeding date and locations.

Book CHARACTERIZATION of VERNALIZATION and PHOTOPERIOD RESPONSE GENES in HIGH LATITUDE WINTER WHEAT  TRITICUM AESTIVUM L

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In wheat (Triticum aestivum L.), major determinants of plant phenology are physiological responses to vernalization temperature, and day length (photoperiod), conditioned by VRN and the PPD genes, respectively. The objectives of this research were to characterize the allelic variation at the major VRN and PPD loci in a diverse panel of winter wheat genotypes (n = 208) and to associate the allelic variation with phenologic, agronomic and adaptation traits. The panel was genotyped using allele-specific markers of the major VRN and PPD loci; VRN-A1, VRN-B1, VRN-D1, VRN-B3, PPD-A1, PPD-B1, and PPD-D1. The photoperiod-sensitive alleles Ppd-D1b and Ppd-A1b were present in 127 and 166 genotypes, respectively. Genotypes with different alleles at PPD-D1 and PPD-A1 varied for number of days to booting, heading, anthesis, and maturity as well as, height and yield. Variation at the VRN loci was minimal. Genotypes with photoperiod-insensitive alleles had higher stability for days to anthesis, than photoperiod-sensitive genotypes.
