Opis:: In the spring of 2012, sophora (Sophora alopecuroides L.) plants showing symptoms of leaf yellowing, little leaves and stunting were observed in Firooz-kuh (Tehran province), Sari (Mazandaran province) and Urmia (West Azerbaijan province) in Iran. Symptomatic plants from the three locations were subjected to nested polymerase chain reaction (PCR) to amplify 16SrRNA using primer pair P1/P7 followed by primer pair R16F2n/R16R2. Th e amplicons were purifi ed, sequenced and the nucleotide sequences were analyzed by virtual restriction fragment length polymorphism (RFLP). Th e phytoplasmas associated with the yellows disease were identifi ed as members of the 16SrIX group (Candidatus Phytoplasma phoenicium) and the 16SrXII group (Candidatus Phytoplasma solani). Th e two phytoplasmas were placed in 16SrIX-C and 16SrXII-A subgroups, respectively, in constructed phylogenetic trees. Th is is the fi rst report on sophora yellows associated with Candidatus Phytoplasma phoenicium.

Opis:: The inheritance of light-cream coloration of vegetative parts in yellow lupin plants was studied. It was found that this trait is inherited monomerically. In homozygous system the gene responsible for light-cream coloration has a plieotropic action. Among others it causes a lower fertility and reduction of seed yield per plant. In heterozygous system symptoms of heterosis are observed. In many aspects the action of dilutus gene is similar to that of dwarf gene in yellow lupin previously described by the authors of this paper.

Opis:: The Czech winter wheat cv. Regina which does not possess specific genes for powdery mildew resistance except Pm5 was crossed with the cvs. Florida, Tjelvar, Agra, Olymp and Sabina, all possessing T1BL-1RS and the dominant suppressor SuPm8, with Riebesel 47/51 possessing substitution 1R-1B and SuPm8 and with the T1BL-1RS cvs. Sparta, Iris, Mona without SuPm8. Powdery mildew isolates avirulent on Pm8 and virulent on other Pm genes were used in the trials. Tests for resistance were carried out either on seedlings at the first leaf stage or on detached leaves cultured on benzimidazolagar. No segregation for resistant plants in F₂ of all crosses of the cv. Regina with cultivars possessing T1BL-1RS and SuPm8 indicates that Regina has SuPm8. The segregation ratio 3 resistant: 13 susceptible in the F₂ population of crosses between the cv. Regina and cultivars possessing T1BL-1RS and no SuPm8 also confirms the presence of SuPm8 in the cv. Regina. The obtained results also indicate that expression of Pm2 and Pm4b is not affected by SuPm8 and that SuPm8 does not affect stem rust resistance gene Sr31 located on 1RS segment.
