title: The inheritance of node number and rate of node production in Brussels sprouts.
abstract: The total vegetative node number, rate of node production and number of sprouts over 13 mm diameter were recorded for 10 F1 Brussels sprout cultivars and 45 progenies derived by intercrossing and selfing them. Significant differences, resulting from additive gene action, were found between the 10 cultivars and between their progenies for both characters. For total node number there was also evidence of dominant gene action. Total node number and rate of node production were closely correlated as were total node number and the number of harvested sprouts. The factors causing differences in rate of node production are indicated and the relationship of this character to other Brussels sprout yield components is outlined.
