United States, Kansas (developed)
Winter durum / AZ ms populations PI 508103 and PI 573006, F2
Several Kandur winter durum lines were crossed to Arizona population PI 508103. The population has been grown for 11 years in western Kansas, every second year 40 to 60 F2 male sterile plants were identified three to five days post flowering. Seed set is generally approximately 80%. This population was grown adjacent to populations based on Arizona population PI 573006 almost every year; it is presumed that pollen was exchanged over time with those populations. Therefore it is unknown which of the potentially present three unlinked recessive male sterile genes is predominate in this population. No artificial selection was carried out for any character other than for height (semi-dwarf) and maturity (against late heading). This population is a source of recessive male sterility and will segregate at least 25% male sterile plants. It is a genetically diverse population. The winter hardiness found in the population is the minimum required to survive the average winter in Kansas without damage.
