Narrative
These six lines are donor parents to BC-NAM populations recently developed and described in the article Patil, N. et. al. “Registration of Sorghum [Sorghum bicolor (L.) Moench] Backcross-Nested Association Mapping (BC-NAM) Families in a BTx623 or RTx436 Background” Journal of Plant Registrations https://doi.org/10.1002/plr2.20286 . Mapping Population narrative: Two sorghum [Sorghum bicolor (L.) Moench] backcross-nested association mapping (BC-NAM) populations (Reg. No. ) have been developed comprised of 30 families totaling 2,189 BC1F4 lines using an elite B or R line as the recurrent parent. The families were derived from unadapted founder lines that were backcrossed to BTx623 and/or RTx436 based on the fertility reaction score and phylogenetic analysis of the founder lines. These unadapted founder lines were selected based on agronomic fitness, breeder desirability, and genetic diversity and represent range of races and working groups. The 30 families were developed from 27 founder parents - three of the founder parents were backcrossed to both recurrent parents to provide a genetic relationship across all 30 families. Each family consists of 45-100 BC1F4 lines selected for standard agronomic fitness, and each population was genotyped using genotype-by-sequencing. To identify families that possess (or segregate for) traits of interest, 13 lines from each population were randomly selected and phenotyped for a range of agronomic and stress tolerance traits. These BC-NAM populations, which are adapted to U.S. production regions and possess novel genetic diversity, have application in genetic research and sorghum breeding programs to diversify their R and B line parental heterotic pools and as a mapping resource for traits of interest.
