POTATO.BLACKLEG.BAINS.1999

 
METHOD: Visual Examination CONDITIONS: Green House - 18h light at 18-24C. METHOD NARR: Freshly cut leaf petioles were inserted to about 5mm in 50 grams of sterile sand drenched with 17ml of inoculum. The length of the rot develocorded 72 hours post-inoculation. Hybrid and cultivar scores are also reported. Wild species were tested using 5 petioles and the experiment was repeated once. RESULTS NARR: A large # (50 0f 162) of chc, and a high % off 6, 50%) were resistant or highly resistant. 100, 97 and 95% can, tarand spg clones were eiter susceptible or highly susceptible, respectively. AUTHOR EXPLANATION: Mean rot lengths: 0-5mm = Highly Resistant, 6-10mm = Resist >50mm = highly susceptible.
