| SHORT STEM. Having a stem shorter by 12.0 cm than that of the standard
AD-7291 (110.0 cm) Triticale Persenk (98.0 cm) is most suitable for
cropping using an intensive technology to produce high grain yield/ha. It
is distinguished for a high resistance to lodging. RESISTANCE TO DISEASES. The studies conducted in the course of 6 years (1981-1986) showed that under laboratory and field conditions Triticale Persenk had not been attacked by powdery mildew. It possesses a high resistance to stem and yellow rust and a very good resistance to brown rust. In comparison with wheat it is distinguished for a higher resistance to root rot which makes Persenk suitable for growing an stubbles. DROUGHT RESISTANCE. In contrast to wheat and barley Persenk is distinguished for a significantly higher drought resistance . Its deeper root system (a character obtained by rye) allows it easily to overcome the negative effects of the extreme soil and air droughts. EARLINESS. According to data of the State Varietal Testing Triticale Persenk matures by 5 days earlier than the standard AD-7291 and by 3 days earlier than the most widely distributed in Bulgaria winter soft wheat Sadovo 1. PROTEIN. One of the highest breeding qualities of Triticale in comparison with wheat and barlew is its higher protein content in the grain. According to data of the State varietal Testing Persenk contains over 1.5% more protein than the standard AD-7291. Having in mind that AD-7291 on its side forms more protein than the winter soft wheat Sadovo 1 the higher protein content of Triticale makes it very valuable for the animal husbandry. For the time being the plant protein production is basically on the account of cereal crops wheat and barley, which have a low protein content. The increase of the grain protein content as many as 1% (like Triticale Persenk) represents a great national task. This will enable us to solve partly the protein problem in the country. TRITICALE FIRST PRODUCTION TEST IN THE REGION OF ACID SOILS. In our country a significant part of the arrable land is situated in upland and montain regions distinguishing for their poor soil fertility. Another part of about 370,000 ha are with an increased soil acidity. On such soil wheat, barley, maize, sunflower etc. are highly succeptible and yield low, whereas Triticale shows a high tolerance. At the first production test in a region of acid soils at the farm antonovo, Targoviste Country Triticale Persenk exceeded in grain yield/ha the winter soft wheat variety Pliska by 28.9% and at the farm of Sokolovo village, Gabrovo Country it exceeded the barley variety Miraj in yield by 35.3%.
