A population of meadowfoam ( Limnanthes alba Hartw .) was subiected to mass selection for early and late flowering time for two generations. Selected plant bulks were grown in C 1 and C 2 generations along with the original population (C 0 ). The responses to selection were significant in both generations. Heritability estimates assuming random mating, ranged from 0.24 to 0.73. Flowering time involved phenotypic assortative mating, which was discussed for its effects on the herltability estimates and population structure of outbreeding species. Early flowering cultivars of meadowfoam would be desirable in a double‐cropping scheme
