EFFECT OF SHORT-TERM VERNALIZATION ON AADH1-SPN GENE EXPRESSION AND TYPE OF PLANT DEVELOPMENT IN RYE HYBRIDS BETWEEN SECALE CEREALE L. AND S. MONTANUM GUSS
There was studied segregation in the F2 progeny of rye hybrids from crossing Secale cereale L. with S. montanum Guss. on isozyme loci Aadh1 (aromatic alcohol dehydrogenase) and Skdh (shikimate dehydrogenase) as well as on a type of plant growth (spring vs. winter). F1 plants were both spring and winter. The F2 progeny were derived separately from spring and winter plants of F1. In the latter case, sowing was made with dry seeds after 7-day vernalization. There was found co-segregation on the Aadh1-Spn gene and spring type of plant development. In the F2 progeny from winter plants F1, short-term vernalization caused a significant increase in spring plants as compared with winter ones; with that, more than a half of homozygotes SpnSpn turned to be spring ones.
