- Based on data from Deptan, in 2005 soybean production 808 t/ha and then reduction in 2006 and 2007 is 748 t/ha and 593 t/ha, while in 2008 to increase the production of 776 t/ha and 966 t/ha production in 2009, while the national requirement is 2,2 milion tons/year (Deptan, 2009). Efforts to increase soybean production plant breeding can be done by using colchicine. This research to determine the effect of concentration and old of giving colchicine on soybean varieties Argomulyo. The results of research Sofia (2007 a), shows that the average weight of 100 soybean varieties Wilis with 1500 ppm of 9,7 g heavier than controls only 8,5 g. The research is a two factor factorial experiment arranged in randomized. The first factor is concentration of giving colchicines (C) with 3 level and factor II is old of giving colchicine (L) with the 3 level and repeated three times. Perception variable is high of plant, number of leave, number of branch, wide and long of stomata, time of the first flower, number of flower, number of polong, age harvest, heavy run dry of 1000 seed, productivity of check treatment, and number of chromosome. The results showed the concentration and old of giving colchicine an interaction on plant height (aged 11 to 21 dap) and number of branches (age 31 to 36 dap). Combination treatment C0L2 (concentration 0 ppm with colchicine immersion length 20 minutes) is the best combination. Separately, the concentration of giving colchicine has not been able to increase the growth and yield of soybean, but the concentration of 300 ppm giving colchicine has been able to double the number of chromosomes (2n = 49) more than those who were not given colchicine (2n = 40). Old of giving colchicine treatment had no effect on all parameters were observed except in the number of leaf age 21 dap. Pursuant to correlation analysis indicate that the relation of number of chromosome with longly of stomata is positive is mean more the number of chromosome than amount hence long stomata also. While high of plant, number of branch, and wide of stomata have the character of negative is mean more the number of chromosome hence short plant, a little number of branch, and small of stomata.
