Seed stocks (designated as AKM 2068 and BKM 2068, respectively) were obtained from Fort Hays Branch Experiment Station, Kansas State University, USA. The maintainer line was derived at Hays, Kansas, by crossing Tift 23DB with PI 185642. Tift 23DB is a maintainer line of Tift 23DA developed at Tifton, Georgia, USA. PI 185642 was collected in 1949 from a market in Kumasi, Ghana, and supplied by the Southern Region, Plant Introduction Experiment Station, Georgia, in 1971. AKM 2068 was derived by backcrossing the initial maintainer line seven times into the cytoplasm of Tift 23DA with continuing pedigree selection. ICMA 2 and ICMB 2 were selected from AKM 2068 and BKM 2068 for downy mildew resistance in the downy mildew nursery at ICRISAT Center following two generations of plant(A) x plant(B) crossing with pedigree selection.
