Seedling Emergence and Phenotypic Response of Common Bean Germplasm to Different Temperatures under Controlled Conditions and in Open Field

摘要: Rapid and uniform seed germination seedling emergence under diverse environmental conditions is a desirable characteristic for crops. Common bean genotypes (Phaseolus vulgaris L.) differ in their low temperature tolerance regarding growth yield. Cultivars tolerant to during the stages carriers of grain quality standards demanded by consumers are needed success crop. The objectives this study were i) screen phenotypic response germplasm range temperatures controlled chamber field display stress-tolerant with good agronomic performances yield potential, ii) compare seedlings environment open assess efficiency genebanks standard tests predicting performance seeds field. Three trials conducted 28 dry low, moderate warm temperature. Morpho-agronomic data used evaluate different genotypes. Cool resulted reduction rate genotypes, however, early could be genetic control these processes need further research suitably modeled. Nine groups arose from Principal Component Analysis (PCA) representing variation time proportion indicating trend lower large extra-large seeded Screening chambers showed several as landraces 272, 501, 593 cultivar Borlotto, stress-tolerance at high potential that valuable material breeding programs. Additionally, erosion was assessed. Regarding commercial traits, sowing reached larger size crop higher compared warmer time. Therefore, strongly recommended.
