Classification of growth habit(vernalization reguirement) of rye, oats and triticale

This study was carried out to evaluate the minimum duration of low temperature treatment required for vernalization of rye, triticale and oats varieties in Suweon, Korea. Low temperature(4℃) treatments for vernalization were made in green-seed(Budding Seed) stage for different duration such as ten, eight, seven, six, five, four, three, two, one and zero weeks, respectively. After treatment, all of the treated plants were transplanted into the greenhouse with 25℃/20℃(day/night) and 24 hour-day length condition to be grown until flag leaf emergence. And then, days from transplanting to flag leaf emergence were observed and the results was shown as follows : Five varieties, including ‘Megwiri’ appeared to be grade Ⅰ for growth habit, one, grade Ⅱ, two grade Ⅲ, and one, grade Ⅳ in oats. In triticale two varieties, including ‘Sinkihomil’ appeared to be grade Ⅲ, five, grade Ⅱ, and one, grade Ⅳ. In rye two varieties, including ‘Karlshulder (Spring)’ and ‘Sorom’, grade Ⅰ, one, grade Ⅳ, three, grade Ⅵ, six, including ‘Paldanghomil’, grade Ⅶ, one, grade Ⅸ, and two, beyond grade Ⅹ.
