成果の概要

Our Project aims to develop early maturing quinoa with enhanced resilience to climate change in the Bolivian Altiplano (4,000 MASL), by providing an escape mechanism to short rainfall and prolonged drought period, and seasonal low temperature (winter frost). I, therefore, traveled to Bolivia to conduct field experiments in the PROINPA (アンデス農業研究普及機関) Research Station aiming to identify Quantitative Trait Loci (QTL) associated to early maturity.
Seeds of breeding lines harvested last April were threshed, cleaned, and placed in individual bags for storage. Subsequently, a drip irrigation system was set up to secure water supply, since rainfall pattern is very unstable in the region. The seeds of each breeding line were then sown in wet soil and covered lightly. The experiment was set in a Randomized Complete Block Design (RCBD) with three replications. The main parameters to be evaluated will be flowering and maturity date.
