| Morphological Description Triticale Persenk (Fig. 1) emerges with a light-ross coleoptile. It forms an half-erect rosete and has an average ability of tillering. The leaves are medium wide being dark green together with the stem till the onset of the milky-wax maturity. The spikes are white with awns and hairy having a length of 8-10 cm. They are cylindrical with a slightly characteristic sharpening to the apex. In a normal sowing the ear spikelets form 4-5 grains. The shoot edges are covered with well-expressed hairs. Under the ear the stem is hairy. The paleas are also hairy forming a well expressed edge and ending with long awns. The grain is egg-shaped, medium-large ending by a brush which is well-expressed. It is distinguished for its slight ventral crease. The seed coat is slightly shrunken due to genetic determined reasons. Breeding Qualities ECOLOGICAL PLASTICITY. One of the biggest breeding advantages of Triticale Persenk is its high ecological plasticity. This clearly can be seen by the results of the State Varietal Testing (SVT) where on the average in the course of 3 years(1984-1986). Triticale Persenk has exceeded annually in grain yield the standard AD-7291 by 7.6% in 1984, in 1985 by 7.0%, and in 1986 by 9.7%. That stability in years can be indicated with difficulty even in the Bulgarian winter soft wheat Sadovo 1 showing high plasticity which in 1984 stepped back in grain yield to the standard AD-7291 by 1.6%, in 1985 exceeded it insignificantly by 1.4% and in 1986 again exceeding it by 5.6%. PRODUCTIVITY. Triticale Persenk is a variety with high productive potentialities of grain yield per hectar. On the average for 3 years (1984-1986) at the State Varietal Testing it exceeded the standard Mexican Triticale AD-7291 by 9.2% (490.0 kg/ha), the winter soft wheat Sadovo 1 by 5.2% (381.0 kg/ha), the winter rye Danae by 3.7%, and the barley Miraj by 29.6%. In the third year Persenk had also no competition in grain yield on the side of wheat, rye and barley (Table 1). In 1984 at the Varietal Testing Station in Radnevo, Country Stara Zagora, was obtained the highest grain yield per ha of Triticale Persenk - 9060 kg/ha, compared to 8170 of the winter soft wheat Sadovo 1, 7830 kg/ha of barley Miraj, 7940 kg/ha of the rye Danae, 8450 kg/ha of AD-7291. |
