Induced mutations in some wheat (Triticum aestivum L.)‎ genotypes

الملخص EN

This investigation was carried out to induce mutations in bread wheat (Triticum aestivum L.) at the Experimental and Research Farm, Faculty of Agriculture, Al-Azhar University.

Two wheat genotypes treated with different concentration of di methyl sulfouxide and sodium azide.

In general, treatment Misr-1 (sodium azide 4000 ppm) was more effective than another to induce mutation and gave mutant with early flowering (86.95 day) in M2 generation.

The highest grain yield/plant (50.3 g and 47.77g) were obtained from Sids 14 (Di- methyl sulfouxide 2000 ppm) and Misr 1 (Di methyl sulfouxide 2000 ppm) but untreated plant Sids 14 gave 37.43 g..

The variety (Sids 14) was more responsible than the other variety for induction of stable promising mutants according to final results at M2 especially high grain yield/plant.

Using of different mutagen treatment was effective tools to obtained new wheat genotypes, earliness and grain yield.

We can use these new genotypes in breeding program
