Italian Common Bean Landraces: History, Genetic Diversity and Seed Quality
The long tradition of common bean cultivation in Italy has allowed the evolution of many landraces adapted to restricted areas. Nowadays, in response to market demands, old landraces are gradually being replaced by improved cultivars. However, landraces still survive in marginal areas of several Italian regions. Most of them appear severely endangered with risk of extinction due to the advanced...
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 کاملGenotyping-by-Sequencing (GBS) Revealed Molecular Genetic Diversity of Iranian Wheat Landraces and Cultivars
Background: Genetic diversity is an essential resource for breeders to improve new cultivars with desirable characteristics. Recently, genotyping-by-sequencing (GBS), a next-generation sequencing (NGS) technology that can simplify complex genomes, has now be used as a high-throughput and cost-effective molecular tool for routine breeding and screening in many crop species, including the species...
متن کاملDiversity in common bean landraces from south Brazil
Phaseolin is the major protein in legume seeds and has provided evidence for protein diversity studies, particularly for subdividing Phaseolus vulgaris in two major gene pools: the Central American (S-type) and the Andean (T-type) groups. In the work reported here, a total of 73 representative landrace genotypes from Santa Catarina State, Brazil, were evaluated according to their phaseolin patt...
متن کاملPhenotypic Diversity among Croatian Common Bean (Phaseolus vulgaris L.) Landraces
Phenotypic diversity among Croatian common bean (Phaseolus vulgaris L.) landraces was assessed by analysing 12 qualitative and six quantitative traits in 338 accessions collected from all production areas in Croatia. Out of 12 qualitative morphological traits, seed coat colour was the most polymorphic among accessions having the highest Shannon’s information index and discriminating power. Out ...
