A review of Brassica species, cross-pollination and implications for pure seed production in New Zealand

2002

SB329REP-055

The various subspecies, forms and relationships between Brassica species and their relatives are outlined. The extent of seed set following handcrossing between them is reviewed to determine a crossing relationship between the species. The factors affecting contamination in pure seed production are reviewed in relation to the pollen source, pollen transport by wind, insects and animals, bee behaviour, shifting of bee hives, calculation of pollination spread over distance, border zones around crops, flowering time and length of flowering period, self-incompatibility, pollen receptivity and competition on the stigma, pollination groups, seed size of resulting hybrids, germination of hybrids, morphological appearance of contaminant plants, expected standards of purity, paddock history, removing off-types and machinery cleanliness.
