Abstract
Research carried out at the Agriculture Faculty-Tikrit University for the year of 2013-2014, to evaluate colchicine efficiency for inducing genetic variation in three strains (X20, Brown, B62) of white button mushroom Agaricus bisporus as well as for quantitative and qualtitave characteristics in this fungus. The result show that interaction between the strain B62 and concentrations 0.1% and 0.5% were increased the total yield to 23.06 and 18.41 kg/m2 sequentially compaired with 12.06 kg/m2 for the control of the Brown strain. The dry matter of Brown strain reached to 10.98% followed by B62 and X20 which reached to 10.48 and 9.45% sequentially. While X20 have the best ratio of carbohydrates, fat and total soluble solid which reached to 54.38%, 4.77% and 5.18% sequentially. The B62 strain is the highest in protein, fiber and ash content which reached to 32.26%, 16.48% and 16.48% sequentially. The effect of colchicine on the percentage of dry matter and total soluble solids was the best at concentration of 0.3% and fat at concentration of 0.1% significantly. When the ratio was 11.14%, 5.51% and 4.63% sequentially. But it did not affect the other of the qualitative characteristics. The interaction between colchicine and strain it has been found that there are significant differences in the dry matter of the fruiting bodies, between the Brown strain and the concentration 0.1% which reached to 13.47%. The interaction between the X20 strain and concentration 0.5% is the best on all Treatment interaction, which reached to 57.05%. the interaction between the B62 strain and the concentration 0.1% better percent of protein reached to 34.25%. In the percentage of fat, the interaction between the strain and the concentration of colchicine effected significantly, and the best rate is 6.17% at the interaction between the X20 strain and concentration of colchicine 0.3%. The interaction between the B62 strain and concentration 0.1% increased The percentage of fibers to 17.82%. The percentage of ash at the interaction between the strain B62 and concentration 0.1% increased significantly at all treatments obtaining the highest percentage reached to 14.44%. The value of total soluble solids at the interaction between the strain X20 and concentration 0.3% was the highest percentage of all treatments which reached to 6.23%.
