The 'Harosoy' Rps2 isoline L70-6494 appears to have the Rj2 allele for ineffective nodulation with strains in the 122 and cl serogroups of Rhizobi um japonicum. Devine and Breithaupt (1981) screened some germplasm and uniform group test lines for the presence of Rj2 and Rj4. The line L75-11806 (in 1979 preliminary IV) was reported to have Rj2.
