Abstract
The study was conducted at Indonesian Vegetable Research Institute in March to
December 2009 with an altitude of 1250 masl. The objective of study was to
determine the effectiveness of EMS in producing carrots male sterile. The
experiment was arranged in Complitely Randomized Block Design with two
factors and three replication. The results indicate that the local carrot cultivars
have the survival to maturity better than hybrid varieties. The highest percentage
of living plants showed by carrot cultivar origin Cipanas (73.21%). The
percentage of live plants is affected by the EMS treatment only until the age of 60
HST. Increased concentrations of EMS resulted in decreased percentage of live
plants. Increased concentrations of EMS also tends to reduce the weight of
thousand grains carrot seed produced from the M1 generation. Visual appearance
of pollen on all EMS treated the same as the control, that is pithy and bright
yellow. Treatment of various EMS concentrations level provided the individual
has not been effective in producing carrots male sterile.
Key words: carrot, male sterile, EMS.
