ASSESSMENT OF SURVIVABILITY AND GENETIC VARIABILITY INMUTATED POPULATION OF HYBRID CUT CHRYSANTHEMUM CV.LEXY REDD.M. Arpitha, S.K. Nataraj, V. Srinivasa, M. Ganapathi and A.N. RameshAbstract An experiment was conducted at experimental plot at college of Horticulture, Mudigere. Rooted terminalstem cuttings were irradiated with gamma rays (0, 10, 15, 20, 25 and 30 Gy) and the maximum survivalpercentage (100.00) was observed in control (0 Gy) and the minimum (0.00 %) was observed in 30 Gy andbased on the survivability the LD50 was determined to be 25 Gy. High PCV and GCV was observed forplant height, number of leaves, leaf length, leaf width, leaf area, chlorophyll a and b and number of flowersper plant. |
