Evaluation Of Hoplolalmus Columbus Sher Reproduction On Selected Soybean Cultivars Using Greenhouse And Excised Root Cultural Techniques

Abstract

Supramana,. S., S. A. Lewis, J. D. Mueller, B. A. Fortnllm, and R. E. Ballard. 2001. Evaluation of Hoplolaimus columbus Sher reproduction on selected soybean cultivars using greenhollse and excised root cultura[ techniques. Nematropica 31:267-271. Host suitlbility of six soybean cultivars to Hplolaimus rolulIlbuswas evaluated in monoxenic culture and greenhouse experiments. Differences in nematode population development were detected among cultivars. 'Bryan,' was less suitable as a host than 'Braxton,' and 'Centennial.' Suitability of these cultiv21rs for reproduction of H. columbus did not relate to their maturity groups or tolerance rating, a result consistent with previous findings. Key words: Columbia lance nematode, GZvcine max, Hoplolaimus columbus, repmductive factor, resistance, soybe.m, tolerance.
