EVALUATION OF HOPLOLAIMUS COLUMBUS SHER REPRODUCTION ON SELECTED SOYBEAN CULTIVARS USING GREENHOUSE AND EXCISED ROOT CULTURAL TECHNIQUES

Abstract

Host suitability of six soybean cultivars to Hoplolaimus columbus was evaluated in monoxenic culture and greenhouse experiments. Differences in nematode population development were detected among cultivars. [sub1]Bryan,[sub2] was less suitable as a host than [sub1]Braxton,[sub2] and [sub1]Centennial.[sub2] Suitability of these cultivars for reproduction of H. columbus did not relate to their maturity groups or tolerancerating, a result consistent with previous findings.
