Exploiting an Amaranth MAGIC population for improvement of leafy vegetable traits

在这个项目中，我们将使用由世界蔬菜中心开发的一个新的Maganth魔法种群，它捕获了8个亲本和两个物种(疑似艾美耳属和克伦特艾美耳属)的多样性。我们已经对8个亲本品系的基因组进行了测序(捕获序列和结构变异)，并知道它们在目标性状上存在差异，包括开花时间、从茎基分枝(促进再生)和营养状况(特别是在缺水条件下)。我们将对神奇的种群进行基因分型并收集特征数据--既来自南非田间试验中的种群增长(与我们在农业研究理事会的合作伙伴)，也来自使用高度受控的垂直农业系统来模拟不同地点小农的环境条件，与我们的合作伙伴LettUs种植。这项研究将评估环境和基因型对我们关键性状的影响，并确定影响这些性状的基因组区域和差异。

In this project we will use a new Amaranth MAGIC population developed by the World Vegetable Center that captures diversity from 8 parents and across two species (A. hypochondriacus and A. cruentus). We have sequenced the genomes of the 8 parent lines (capturing sequence and structural variation) and know they differ in our target traits, including flowering time, branching from the stem base (enhances regrowth), and nutritional profile (particularly under conditions of water deficit). We will genotype the MAGIC population and collect trait data - both from growing the population in field trials in South Africa (with our partners at the Agricultural Research Council) as well as using highly controlled vertical farming systems to mimic the environmental conditions of different locations of smallholder farmers, with our partners LettUs Grow. The research will assess the impact of environment and genotype on our key traits, and identify genomic regions and differences that impact these traits.
