Abstract: The 41 accessions of lucerne (Medicago sativa, M. varia, M. falcata) were investigated in the field experiment at the Institute of Agriculture in 2008-2009. Experiment period was very favourable for disease spread and development. Resistance between downy mildew (DM) and Sclerotinia crown and stem rot (SCSR) correlated weakly (0.344), the medium correlation (r=0.531) was determined between resistance to spring black stem and leaf spots (SBSLS) and DM, the strong correlation (r=0.704) was found between resistance to SBSLS and SCSR. The medium resistance to SBSLS was characteristic for 17 % of accessions. The resistant to DM were 14 %, and medium resistant were 29 % of accessions. About third of accessions were resistant and medium resistant to SCSR.
41 liucernų (Medicago sativa, M. varia, M. falcata) pavyzdys tirtas 2008– 2009 m. lauko bandymuose Žemdirbystės institute. Bandymo laikotarpis buvo labai palankus plisti ir vystytis ligoms. Tirtų liucernos pavyzdžių atsparumas netikrajai miltligei ir vėžiui koreliavo silpnai (r=0,344), vidutinis ryšys (r=0,531) buvo nustatytas tarp atsparumo askochitozei ir netikrajai miltligei, o stiprus nustatytas (r=0,704) tarp atsparumo askochitozei ir vėžiui. Vidutiniu atsparumu askochitozei pasižymėjo 17 % pavyzdžių. Atsparių netikrajai miltligei pavyzdžių nustatyta 14 %, o vid. atsparių – 29 %. Pavyzdžių, atsparių ir vid. atsparių vėžiui buvo 39 %.
