Kabatiella caulivora (clover scorch). In contrast to previous years where all overseas introductions and most crossbreds were tested for resistance to Kabatiella, only selected clovers are now being screened so as to reduce the number requiring testing to a manageable size. Root rot resistance screening. One hundred and seven clovers selected as low in formononetin, tolerant of clover scorch, mid to late season maturity, and reasonable winter vigour were tested at two sites for root rot resistance. Bluegreen aphid (BGA) resistance screening. Sub clover screening for bluegreen aphid resistance ranked from tolerant to susceptible (ratings at 49 days from commencement). Bluegreen Aphid resistance of some mid season crossbreds. Genetics of BGA resistance in sub clover. Table 5 shows the results obtained for parents and Fl progeny at the conclusion of the experiment.
