Description

The present invention relates to a durable winter durum wheat variety suitable for dry pasta production, which is of superior quality to the mill and pasta industry, which is more generic than conventional varieties.

Under domestic conditions, durum wheat production is severely restricted by cold winter weather. The production risk can be reduced by cultivating durum wheat varieties with higher frost tolerance than winter barley, thus it is possible to supply dry pasta production from domestic sources, to reduce imports and to meet the annual export demand.

Durum wheat has special nutritional qualities that make it suitable for dry pasta making, so it is essential to produce a new breed of raw materials that can be used for processing in the pasta industry, preferably of good quality, regardless of the vintage. The winter durum wheat varieties currently grown in Hungary do not fully meet the expectations of the growers, so there is a demand for new varieties with better characteristics.

Odmadur 1 is a well-known winter durum wheat of 20 varieties. The first leaf has no or very weak anthocyanin coloration, the growth type is erect to semi erect. The frequency of the deciduous flagella is absent or very low. It has an early-to-middling time. The waxiness of the leaf feathers of the flag leaf is medium, the leaf leaf is slightly waxy. Its mucosa does not or only slightly anthocyanin color. Its upper stalk is not or very lightly haired, the stalk is slightly waxed, the stalk is slightly to medium waxed. The plant has a medium height. Its fibers are found along the entire length of the ear, their length is the same as the length of the ear, and their color is whitish. It has a short, slightly colored, compact, parallel shape in profile. The shape of the calyx is elongated, the shoulder of the calyx is prominent and narrow. 35 The tooth is short to medium in length and straight in shape. The outer surface of the sheath is not hairy. The stem of the straw is thin. The shape of the eye is semi-elongated, the length of the base of the hair is medium, it is not or only slightly colored by phenol. In a phytotron test 40, its frost resistance to cold treatment at -13 ° C was 88.1% (Martonvásár, 1996), and its powdery mildew resistance was excellent (OMMI, 1995). The quality of the milling and pastry industry varies considerably depending on the year, with a steel content of 11.0 to 93.0% and a protein content of 11.9 to 12.9% for four consecutive years (Martonvásár, 1994-1997).

GK Tiszadur is a well-known winter durum wheat variety, a standard variety in the small-scale durum variety comparative experiment of the National Agricultural Certification Institute. 50 It has good fertility and is more susceptible to powdery mildew. Semolina seed grain of the variety is of good quality for use in the pasta industry, having an average steel content of 42% and a wet gluten content of 29.7% (OMMI, 1994-1996). The average frost resistance of phytotron is 55.3%, and 71.32% of the plants remain viable under cold treatment at -13 ° C.

The two types mentioned above have the common disadvantage of not having, at the same time, excellent frost resistance, outstanding productivity, good resistance 60 and good technological quality. SUMMARY OF THE INVENTION It is an object of the present invention to provide a durum wheat variety which is more productive, winter resistant, has good milling and paste quality, has a good resistance to powdery mildew and rust.

The above problem was solved by producing durum wheat with a semi-erect growth type, strong flagellate leaf waxiness, medium earing time, parallel shape of the ear, white at maturity, oblique to the ears and half of the ears no phenol or very poor coloring, autumn lifestyle.

The durum wheat variety in question is derived from the combination DF 20582 χ CORALL. The generous DF 205-82 genotype, which is resistant to powdery mildew infection, was crossed with a good quality Coral cultivar of the milling and pasta industry, from which we selected the durum wheat strain, which received state certification as Martondur 1.
