Effective population size (N) of organically and conventionally grown composite cross winter wheat populations depending on generation

Effective Population Sizes (Ne) of three winter wheat composite cross populations (CCPs) that had been maintained under organic and conventional conditions from the F7 to the F12 were analysed. The number of plants (N) needed to maintain an Ne of 5000 for each population was calculated based on the mean variation in the number of gametes per parent Sk2. Variability in kernel number per plant was high, leading to large variations in the...
