Low soil fertility and high weed infestation are the main culprits for the declining maize production inWestern Kenya. Technology packages to address these constraints exist, but their effectiveness is likely to be influenced by variability in soil types and farm management practices in the region. Trials were conducted during the 2008/2009 cropping seasons to investigate the nutrient use e...

Drought stress is one of the leading constraints to wheat (Triticum aestivum L.) production globally. Breeding for drought tolerance using novel genetic resources is an important mitigation strategy. This study aimed to determine the level of drought tolerance among diverse bread wheat genotypes using agronomic traits and proline analyses and to establish correlation of proline content and agro...

Polyploid plants often have higher biomass and superior crop qualities. Breeders therefore search for crop germplasm with higher ploidy levels; however, whether higher ploidy levels are associated with better performance remains unclear. Actinidia arguta and related species, whose commercialized fruit are referred to as kiwiberries, harbor a series of ploidy races in nature, offering an opportu...

this study was conducted to evaluate genetic diversity of durum wheat cultivars using multivariate analyses on agronomic and morphological traits. thirty genotypes were planted in a randomized complete block design with three replications in 2003. agronomic and morphological characteristics including days to flowering, days to pollination, days to maturity, plant height, spike length, grain wei...

Relatively little is known about the genetic control of agronomic traits in common wheat (Triticum aestivum L.) compared with traits that follow Mendelian segregation patterns. A doubled-haploid population was generated from the cross RL4452x'AC Domain' to study the inheritance of the agronomic traits: plant height, time to maturity, lodging, grain yield, test weight, and 1000-grain weight. Thi...

The extreme climate of the Canadian Prairies poses a major challenge to improve yield. Although it is possible to breed for yield per se, focusing on yield-related traits could be advantageous because of their simpler genetic architecture. The Canadian flax core collection of 390 accessions was genotyped with 464 simple sequence repeat markers, and phenotypic data for nine agronomic traits incl...

this experiment was conducted with the objective of evaluating the performance sage (salvia officinalis l.) in different agroecology of ethiopia for morpho-agronomic and chemical traits at wondo genet, hawassa, qoqa and holleta for two years from 2011/2012 to 2012/2013 cropping seasons. data on plant height, branch number/plant, fresh leaf weight/plant, fresh stem weight/plant, above ground bio...

some substitution lines between two parental lines for complex traits allows for the identification of single Genetic analyses of complex traits in wheat (Triticum aestivum L.) chromosomes containing QTLs for those traits (Berke are facilitated by the availability of unique genetic tools such as chroet al., 1992a,b; Cantrell and Joppa, 1991). Single recipromosome substitution lines and recombin...
