Evaluation of salt tolerance in common bean genotypes by ion regulation and searching for screening parameters
The objectives of this work were (1) to screen large collection of bean genotypes for salinity responses and (2) to identify the best traits for screening the bean germplasm in tolerance to salt stress. Sixty-four bean genotypes were subjected to 125 mM NaCl. Plants were grown in hydroponic growing medium in greenhouse. The screening was carried out at early growing stage (25 days old plant). I...
متن کاملAggressiveness of Pseudocercospora griseola strains in common bean genotypes and implications for genetic improvement.
The fungus Pseudocercospora griseola, the causal agent of angular leaf spot in the common bean (Phaseolus vulgaris L.), exhibits a broad pathogenic variability that complicates the development of resistant cultivars. For breeding programs to successfully obtain common bean cultivars with durable resistance, knowing the aggressiveness of different strains, as well as the mechanisms of genetic re...
متن کاملGenetic control of inflorescence in common bean.
The number of pods per common bean plant is a primary component of grain yield, which depends on the number of flowers produced and on the flower set. Thus, a larger number of flowers per plant would increase yield. Lines with inflorescences that had a large number of flowers compared to common bean plants now under cultivation were identified. We analyzed the genetic control of this trait and ...
متن کاملGenetic Diversity of Croatian Common Bean Landraces
In Croatia, the majority of the common bean production is based on local landraces, grown by small-scale farmers in low input production systems. Landraces are adapted to the specific growing conditions and agro-environments and show a great morphological diversity. These local landraces are in danger of genetic erosion caused by complex socio-economic changes in rural communities. The low prof...
متن کاملBayesian Estimates of Genetic Relationships between Growth Curve Parameters in Shall Sheep via Gibbs Sampling
The objective of this study was to estimate variance components and genetic parameters for growth curve parameters in Shall sheep. Studied traits were parameters of Brody growth model which included A (asymptotic mature weight), B (initial animal weight) and K (maturation rate). The data set and pedigree information used in this study were obtained from the Animal Breeding Center of Iran and co...
