Genetic and nongenetic factors influencing deviations from five pappus parts in a hybrid between Microseris douglasii and M. bigelovii (Asteraceae, Lactuceae)



Genetic and nongenetic factors influencing deviations from five pappus parts in a hybrid between Microseris douglasii and M. bigelovii (Asteraceae, Lactuceae)



International Journal of Plant Sciences 153(1): 86-97



The genetic basis responsible for deviations from a basic number of 5 pappus parts was analysed in a cross between M. douglasii inbred strain B14 (0-5 pappus parts, modal number 3) and M. bigelovii strain C94 (4-7 pappus parts, modal number 5). The F1 pappus part number is near 5, and most F2 plants have averages near 5. Offspring of Fsuperscript 2 plants with relatively low pappus part numbers also had low pappus part numbers.
