The mode of inheritance of fifteen induced morphological mutants in diploid wheat Triticum monococcum L. was determined. The results showed that earliness, reduced height, uniculm, liguleless branched spike, compact ear, and free-threshing habit of each of these mutants is the result of a single recessive mutation. Red awns and xantha traits are controlled by two recessive genes with duplicate and inhibitory gene interactions, respectively. Some of the early and dwarf mutants were non-allelic. One dwarf GA3-insensitive mutant with recessive gene action may be a new source. Mutants such as early maturing, dwarf and free threshing habit may be of significance in breeding diploid wheat.

Twelve synthesized ainphiplonds involving Karnal bunt (Neovossia indica)-resisiant accessions of Triticum monococum, T. boeoticum and Aegilops sqiwrrosa and susceptible but otherwise well adapted and high yielding T. Durum cultiviars were evaluated for Karnal bunt resisiance under artificial inoculation conditions. All ihe synthetic amphiploids, except DWI. 5031 x T. monocoirtum aniphlploid, were free from Karnal bunt disease indicating that the Karnal bunt resistance or T. motsococcum, T. boeoticMrn and Ae, squarrosa is expressec in the presence of the dnrum complement. The importance and utilization of the amphiploids fox breeding wheat varieties resistant to karnal bunt are discussed.

Two groups of employed men in an alcoholic rehabilitation program--one referred through an organized policy of constructive coercion and the other volunteer--were compared to test the efficacy of constructive coercion in the rehabilitation process. It was found that the patients referred by constructive coercion were younger, had fewer psychosocial problems, had a higher percentage who were abstinent and had higher rates of compliance with follow-up. A policy of constructive coercion allows earlier identification of workers with alcohol problems and improves the chances for a positive treatment outcome.

The inheritance of isoproturon tolerance exhibited by the selected progenies of durum wheat was investigated. This tolerance to the herbicide isoproturon had been transferred from Triticum monococcum to durum wheat cultivars. It was shown to be conditioned by a single dominant gene
