Notes: Summary Three triticale lines, Siskiyou, M2A-Beagle, and OK 77842 have been reported to possess resistance to bacterial leaf streak caused by Xanthomonas campestris, pv. translucens (Xct.). The three resistant lines were crossed to susceptible lines and crossed with each other. F2, BC1-F1, BC2-F1 plants were inoculated with a mixture of two Xct strains. The segregation data indicate the presence of a single dominant gene in each of the three resistant lines to bacterial leaf streak. These three genes are either the same or closely linked herein designated as Xct1.

Notes: 1- and 2-Chloroanthracenes have been copolymerized with butadiene in the Mutual recipe and in the Mutual recipe with some added benzene. Using charging ratios of 90 parts of butadiene and 10 parts of chloroanthracene in the absence of benzene, the incorporation of the 1 isomer at 62% conversion is 16.9% and the incorporation of the 2 isomer at 80% conversion is 7.3%. In the presence of added benzene (5 ml. to 84 g. charge) the incorporation of the 1 isomer is 21.2% at 39% conversion and the incorporation of the 2 isomer is 9.4% at 53% conversion. The anthracene derivative is incorporated in the polymer chain through the meso positions.
