Abstract: <\/strong><\/span><\/p>\n

Five wheat mutants (T. aestivum L.)<\/em> were induced from the Sonalika variety in addition to the untreated variety which was used as a control. The mutants were planted in the Shibam region-Yemen- in the period 18-22 \/ 6 of 2013 and 2014 under irrigation conditions. Seeds were exposed to irradiation with 250 GY in the Seibersdorf laboratory in Vienna. Evaluation and selection were performed in mutant populations. Results showed that a significant difference between mutants each other in one hand and between mutants and the control in the other hand for grain yield, 1000 kernel weight, length of the spike, number of grains per spike, number of days to heading and maturity, at the same time, a variation was observed in the severity of disease within the planted mutants. A positive correlation was found between yield, spike length and number of grains per spike, while negative correlation between yield, number of days to flowering and maturity, whereas a positive correlation was noticed between spike length and number of grains per spike. Weight of 1000 kernel weight was negatively correlated with the length of spike and number of grains per spike, and the grain yield was positively correlated with the level of resistance of mutant to yellow rust disease. The Erra-008-Sw-4-17 mutant was the highest in the number of grains per spike (47 grain), thousand kernel weight (45gm) and attained the highest yield 3940 kg \/ha. accompanied with more resistance to yellow rust disease 7MR, followed by the Erra-008–11-40 and Erra-008-Sw-17-68 mutants in terms of average yield, number of seeds per spike, thousand kernel weight, and severity of disease which were 23MS and 23MS respectively. The untreated variety was the lowest in yield, a number of grains per spike, and thousand kernel weight registered 2795 kg\/ ha, 38 kernels, and 38 gm, respectively. The highest incidence of yellow rust disease was recorded 30 S for untreated control.<\/span><\/p>\n
