Abstract
ABSTRACT The study was carried out during the summer of 2005 using randomized complete black design with four replications. Seeds of mosaic cotton mutants (MC2 and MC3) producing from M2 plants were used to obtain M3 generation. MC2 plants showed significant decrease in: length of necked region, No. of fruiting branches/plant, No. of bolls/plant, No. of seeds/boll, ammount of chlorophyll A and B in comparison with control plants, while MC3 plants showed significant decrease in : length of necked region and ammount of chlorophyll A and B in comparison with control. No significant differences were shown between the mutants and control in: plant height, No. of inter nodes to the first fruiting branch, No. of vegetative branches, total No. of leaves/plant, No. of days to first flower, first boll opening and boll weight.
