Abstract

ABSTRACT: The present study was carried out at the farm of the Rice Research and Training Center, Sakha Agriculture Research Station, Kafr El-Sheikh, Egypt during 2011, 2012 and 2013 rice growing seasons. Three rice varieties viz. Sakha 105, Sakha 102 and Giza 178 were used. Dry seeds of the above maintained rice varieties were treated with different doses of gamma rays (100 – 200 – 300 and 400 Gy) for raising M1 generation. M1 plants were established in the 2011 season to be grow as M2 generation in 2012 season and the selected mutants have been advanced to M3 generation in 2013 rice growing season. The results of the selected M3 mutants indicated that there are significant variations between the mutants and their parents for plant height, grain yield as well as drought tolerance. It could be concluded that mutation technique have shown to be very useful in rice improvement, especially for characters controlled by closely linked` genes that are difficult to break by gene recombination. Using irradiation by gamma ray exhibited different genetic variability such as semi-dwarf, early heading and high grain yield. The induced genetic variability was more important as it can be used directly in rice breeding program through selection or by hybridization with the commercial cultivars.
