Abstract: The aim was to study the growth and genetic variation effects of carbon ion implantation and implantation times on different kind of sunflowers. Carbon ions were implanted into‘Ba-sunflower138’,‘Ba-sunflower136’and‘Ba-sunflower118’seeds in dose of 5×1013 C/cm2 respectively, planting and harvesting the seeds to get irradiated again. The author continued the field test, observed the growth conditions of different Ba-sunflowers, and analyzed the genetic variation with RAPD. The germination rate and a number of traits like plant height, stem diameter, leaf number and yields of‘Ba-sunflower138’had a significant improve, while the twice-irradiated group just the opposite; the variation of‘Ba-sunflower136’and‘Ba-sunflower118’was not significant. At the molecular level, the genetic distance with the control group of once and twice-irradiated groups was 0.1111, 0.1087 in‘Ba-sunflower 138’; 0.0680, 0.0303 in‘Ba-sunflower136’and 0.0625, 0.0435 in‘Ba-sunflower118’. Carbon ion implantation had a significant effect on the growth and development of‘Ba-sunflower138’, and its effect varies with irradiation times, at the same time, it could cause genomic variation in the three kinds of sunflowers.
