Description

The importance of introduction of winter wheat into the cultivation of the Ural-Siberian zone of Russia is conditioned by many advantages of this crop compared to spring wheat. It consists both in "diverting" spring-summer droughts and 35-40 days earlier ripening than of spring wheats, also changing the whole technology of processing the land for spring sowing in autumn, etc.

The produced winter wheat cvs Kulundinka, Bagrationovskaya, Lutescens 4 and Zalarinka exceed winter wheat cvs of the World Collection of this crop in VIR in winter hardiness. They are distinct in their stable wintering in forest-steppe and steppe zones of Siberia, high yield performance (twice more than that of spring wheats), high grain and flour technological properties.

Cv. Kulundinka - stable winter hardiness in the dry-steppe areas of eastern Kazakhstan, yield - 34-40ctn/ha, resistant to drought and logging. 1000 grain weight - 28-31g, grain wet gluten content - up to 35%, good flour bread-making properties, flour strength - 207a.u. It was produced in co-operation with North-Kulunda Experimental Station.

Lutescens 4 -intensive wheat cv, resistant to logging. 1000 grai weight - 38-45g, good and excellent flour bread-making properties, protein content - 14.5%, wet gluten content - 30%, flour bread-making strength - 430 a.u., yield performance - 36-43 cntn/ha.

Zlarinka - intensive wheat cv, resistant to logging. It is distinct in its high winter hardiness and drought resistance, good flour bread-making properties, protein content - 16%, glutent content - 44%, 1000 grain weight - 34g, yield performance - 60cntn/ha (East-Siberian region), resistant to retentive late frosts. It was produced in co-operation with the Siberian Institute of Plant Physiology and Biochemistry, SB RAS.

Bagrationovskaya - intensive cv, resistant to drought, logging and grain falling, 1000 grain weight - -38-42g, yield performance - up to 51.8 cntn/ha, excellent flour bread-making properties, wet glutent content - 33%, flour strength - 368-378 a.u. It was produced in co-operation with the East-Kazakhstan Experimental Station.

Novosibirskaya 32 - intensive wheat cv., produced on the base of hybridisation of purple wheat-grass inbread clones with winter common wheat cvs and is meant for cultivation in the forest-steppe zone of Siberia, suitable for modern cultivation technologies, mechanised harvesting and processing. Plants have half-creeping tillered shape, average hard stem, pyramid-shaped spike, 1000 grain weight - 336g, wet protein content - 13.8, average grain yield - 33.5cntn/ha.

These cvs are considered strong in their bread-making properties.

Since 1996 cv Bagrationovka has been accepted as standard in winter hardiness among winter wheat cvs.

Technical-Economic Advantages

  • In general, winter wheat cvs have a number of advantages over spring wheats in Siberia :

  • 1. winter wheat sowings for making yield - 35-40 ctn/ha satisfy their needs for moisture at 70-80% due to winter precipitation, whereas this index is 15% in spring wheat sowings. Thus, winter wheats are practically not affected by or resist spring-early-summer droughts, which are observed during 7 years out of 10 in the Ural-Siberian region, lighter;

  • 2. winter wheat sowings ripen and are ready for harvesting under more favourable weather conditions of the end of July - the beginning of August, compared to spring wheats ahrvested in autumn, i.e. September-October. It allows to obtain higher quality winter wheat grains with no extra energy consumption;

  • 3. harvesting winter wheats in the middle of August alow to plow land for spring sowings on August. Such land is referred to half-fallow that enables to increase spring crops yield performance for the next year. Therefore, winter wheats are a very convenient and economically profitable precursory in sowing circulation;

  • 4. cultivating winter wheats in the zone with short vegetation period, limited by natural factors allows to considerable reduce field work load during spring sowings in spring and in autumn during harvesting;

  • 5. economic advantages of this crop in the land-farming of the Ural-Siberian zone consist in the thing that its grain cost price can be 30-40% of winter grain. i.e. twice or thrice cheaper.
