【 摘 要 】

New varieties of spring triticale were taken an assessment in the conditions of the Republic of Chuvashia. It's elicited that Saur variety is characterized by the biggest number of productive footstalks with kernel weight per spike and thousand-kernel weight. Variety Rovnya had the least number of productive footstalks. This variety showed minimal number of spikelets in a spike. At the same time, Rovnya had the biggest amount of grains. Variety Ulyana was inferior to all other varieties in kernel weight per spike and thousand-kernel weight. Variety Khaikar true of fact exceeded the standard in the number of productive footstalks, kernel weight per spike and thousand-kernel weight but in the number of spikelets and seeds in a spike was equal to Ulyana. The varieties Saur and Khaikar exceeded the standard in crop yields. Field germination rate turned to be rather low. In fact, Ulyana's seeding rate has not affected the index. It fluctuated from 56, 0-56, 5%. Seeding density depended on both seed application rate and the variety itself. Number of seedlings with seeding rate growth increased of Ulyana variety from 225 to 339 and 276-372 pcs/m2 of Khaikar. However, with increase of the seeding rate the survival capacity and viability of plants decreased. Especially sharp decline was common to the seeding rate of 6 ml of germinating seeds. Optimal seeding rate of triticale varieties in Chuvashia is 5 ml per 1 ha.
