| Abstract | Thirty-one selected soybean genotypes including cultivars and breeding lines developed for the north of Mato Grosso do Sul, south of Mato Grosso, and the " Triângulo Mineiro" region of Minas Gerais states, Brazil, were evaluated for resistance to Rotylenchulus reniformis in a greenhouse experiment. Plants of each cultivar were individually inoculated with 1,000 eggs and vermiform Rotylenchulus reniformis nematodes. The reproduction factor (RF) and the number of R. reniformis/g of roots were calculated for each cultivar 60 days after inoculation. The cultivars BRSMG 250 [Nobreza], TMG115RR, TMG121RR, MGBR015849, TMG113RR, BRS Jiripoca, and M-SOY 833RR gave values of RF and number of nematodes/g root that did not differ statistically from those for the known resistant cultivar Custer. Most of these cultivars are resistant to the soybean cyst nematode (SCN) as well, indicating that the identification of cultivars that can be recommended as resistant to the reniform nematode would be accelerated by giving first priority to the evaluation of SCN-resistant cultivars. |
