In 4-year trials, seeds of the Brassica campestris subsp. pekinensis cultivar Chen-li were sown in a greenhouse in the second half of Jan. for the Apr. harvest, and sown in mid-July for the Oct. harvest. The seedlings were pricked out into 10-cm pots and later planted individually in 5-litre pots. Plants for the Apr. harvest were grown in the greenhouse and those for the Oct. harvest, outdoors.
