In general the rate of frequency of mutants in the X2 is higher at the polyploid level than the diploid chiefly on account of the tolerance of chromosome rearrangement at the former level (cf. PBA, Vol. XXIV, Abst. 1838). Experiments on the oats Klock II and Same and the wheats Scandia III and Svalof Kolben have shown that in both cereals X irradiation may result in mutants with improvements in such characters as yield, quality, date of ripening, straw stiffness and 1000-kernel weight.
