2012 Annual Report
In 2011, approximately 42 populations were grown Blacksburg, VA that combined the low phyate trait with better agronomic performance including crosses to lines that may improve field emergence. The populations were in the F2 generation and three 10' rows per population (pop) were planted. The first row of each pop contained 60 seeds and those rows were assayed for emergence with stand counts. Percent emergence and visual observations were used to select 26 populations for marker-assisted selection. DNA was isolated from individual F2 plants in each population; 320 plants were assayed in Lpa pops and 80 in Mips1 pops. Thus far, approximately 6,000 F2 plants have been assayed with single nucleotide polymorphism (SNP) markers.
