Table 2 Effect of parental populations, varieties and plants on the fitness components of their hybrid (Br×Bn and Bn×Br) offspring. Variables brpop and bnpop indicate the effects of parental Brassica rapa populations and B. napus varieties, respectively, brpar and bnpar the corresponding effects of individual parental plants, and type the effect of reciprocal crossing direction. Only results for components included in the combined fitness are shown
