"Any regional brand needs to be based on a varietal," Mr. Olsen-Harbich said.
Phylogenetic analysis based on inter-varietal polymorphism showed that the very old cultivar Erythrospermum 841 was the most genetically distinct from the other nine cultivars from Kazakhstan, falling in a clade together with the American cultivar Sonora and genotypes from Central and South Asia.
We have used transcriptome and restriction site−associated DNA sequencing to identify varietal SNPs among 18 G. hirsutum varieties based on the rationale that varietal SNPs can be more confidently called when flanked by subgenome-specific SNPs.
The accuracy of varietal classification based on the physical properties of seeds was found to be most satisfactory.
Genotypes were chosen from each of the five sub-populations and two varietal groups based on popularity for genetic and physiological studies.
Fig. 2 Classification of the Indian cultivars carrying Hwa1-1 or Hwa2-1 gene and 13 reference cultivars into four varietal groups based on banding patterns of 39 DNA markers covering all 12 rice chromosomes.
However, when these varieties were evaluated based on farmers' preferences in participatory varietal selection, BRRI dhan53; a short duration variety with medium slender grains was the most preferred, followed by BRRI dhan54 and BRRI dhan40 for wet season, and in the dry season BRRI dhan47 was the most popular variety followed by BRRI dhan61, which agreed with ranking based on yield.
To evaluate these scenarios for the maize supply chain, we propose a combination of a model of farmers' varietal choice (based on profit evaluation at the field level, taking into account transport costs as well as price and cost differences between GM and non-GM products) and a spatially-explicit gene flow model.
Wheat is grown in 30 of China's 31 provinces in 10 major agro-ecological zones based on wheat type, growing season, and varietal response to temperature and photoperiod [1], [2].
Four accessions, namely, GT97-40, FN15, YG18, and FN02-3924, were newly released based on the first and second cycles of varietal demonstrations under the Chinese National Sugarcane Industry Technology System.
