โœฆ Synopsis

About 25,000 M s and M~ seedlings of the bread wheat variety C. 591 were tested for resistance to 3 races of stem rust. A mutant with resistance to race 40 of stem rust was found in a family derived from treatment with 16,000r of X-rays. No other mutant was found. Albina seedlings were found to be totally free of rust infection. From the present study it seems that mutations for rust resistance can be induced in bread wheat by ionizing radiations but the frequency of such mutations appears to be very low.

Monogenic lines resistant to leaf rust of spring and winter wheats were grown in the world wheatproducing areas from 1970 through 1975. Lines containing the alleles Lr9 (Wi), Lr9 (Tc), and Lrl9 (Tc) were more resistant to the leaf rust pathogen than those containing Lrl (Tc), -1 (Wi), -1,3 (Wi), -2A

Five spring wheat cultivars differing in partial resistance (PR) to wheat leaf rust were tested at Wageningen (the Netherlands) on a sandy and a clay site, El Batan (CIMMYT, Mexico) and Ponta Grossa (Brazil) over two years . The cultivars were Skalavatis 56, Little Club (both very susceptible), West
