Description:
14 cultivars were interpollinated for 3 cycles. This broad-based population was subjected to selection for postharvest respiration rate. The respiration rate of 450 roots was determined. Forty-two roots with relatively high respiration rates were selected, planted in the greenhouse, allowed to randomly interpollinate and seed from all plants bulked for the next cycle. For the 2nd cycle, respiration rate was measured on 100 roots and 31 roots with relatively high respiration were selected.
