Hierarchical multiple-factor analysis for classifying genotypes based on phenotypic and genetic data
A numerical classification problem encountered by breeders and gene-bank curators is how to partition the original heterogeneous population of genotypes into non-overlapping homogeneous subpopulations. The measure of ...
Decomposing additive genetic variance revealed novel insights into trait evolution in synthetic hexaploid wheat
(Frontiers; Frontiers Media, 2018)
Towards molecular breeding of reproductive traits in cereal crops
The transition from vegetative to reproductive phase, flowering per se, floral organ development, panicle structure and morphology, meiosis, pollination and fertilization, cytoplasmic male sterility (CMS) and fertility ...
Numerical classification of related Peruvian highland maize races using internal ear traits
Maize (Zea mays L.) landraces are an important source for the genetic improvement of the crop. Classification of genetic resources requires both appropriate descriptors as well as sound numerical and statistical methods. ...
Assessing morphological and genetic variation in annatto (Bixa orellana L.) by sequence-related amplified polymorphism and cluster analysis
Annatto (Bixa orellana L.) is the sole source of bixin, a seed-specific red apocarotenoid pigment used worldwide. Genetic improvement of annatto has focused on increasing bixin content as well as fostering traits that favor ...
Quantitative trait loci mapping for adult-plant resistance to powdery mildew in bread wheat
(American Phytopathological Society, 2006)
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is a major disease to wheat (Triticum aestivum) worldwide. Use of adult-plant resistance (APR) is an effective method to develop wheat cultivars with durable ...
Molecular mapping for resistance to pea rust caused by Uromyces fabae (Pers.) de-Bary
Pea rust caused by Uromyces fabae (Pers.) de-Bary is a major problem in warm humid regions causing huge economic losses. A mapping population of 136 F6:7 recombinant inbred lines (RILs) derived from the cross between pea ...
Novel structural and functional motifs in cellulose synthase (CesA) genes of bread wheat (Triticum aestivum, L.)
(Public Library of Science, 2016)
Cellulose is the primary determinant of mechanical strength in plant tissues. Late-season lodging is inversely related to the amount of cellulose in a unit length of the stem. Wheat is the most widely grown of all the crops ...
