Influence of a location on productivity of the Austrian wheat varieties.

According to 2014-2016 data, economic and biological indicators of Austrian wheat varieties are characterized by high variability depending on a location. The productive tillering in Dedoplistskaro exceeds the same indicator in Akhaltsikhe almost twice, the average indices were received in Khashuri and Telavi. Ear length indicators on regions almost didn't differ from each other. The same results are received on the number of spikelets in an ear. By the number of grains in an ear differ Dedoplistskaro and Akhaltsikhe regions. By the mass of grains in one ear the difference between the regions is insignificant. The high rate of mass of 1000 grains was received in Telavi region. The analysis of indicators shows that the climatic conditions of Dedoplistskaro and Akhaltsikhe regions suit the Austrian wheat varieties much better than the conditions of Khashuri and Telavi regions. In Dedoplistskaro, yield on 1 m2 fluctuates within 535.0-888.5 g, yield of 50 ears - 88.0-124.0 g, average yield - 5.4-8.9 tons. All varieties exceed the standard in yield. Respectively in Telavi, these indicators are: 630.0-724.0, 101.0-124.0 and 6.1 -7.2 tons; in Khashuri - 475.5-639.0, 93.0-105.0 g and 4.8-6.4 tons; in Akhaltsikhe - 531.5-783.5, 110.0-130.0 and 5.3-7.8 tons. In Dedoplistskaro the varieties Amandus (8.9 t/hectare), Amikus (8.1t/hectare) and Fidelius (8.1 t/hectare) differ by high yield; in Telavi - Galus (7.2 t/hectare) and Lukulus (7.0 t/hectare); in Khashuri - Amandus (6.4 t/hectare); in Akhaltsikhe - Amikus (7.8t/hectare), Urbanus (7.7t/hectare) and Amandus (7.0 t/hectare); in Telavi and Akhaltsikhe regions the difference between varieties is insignificant. Influence of a location is even more obvious on the indicators of separate varieties. Plant height of variety Amandus on regions fluctuates within 70.6-81.3 cm, productive tillering 2.2-8.2, ear length - 8.5-10.6 cm, number of spikelets in one ear 15.3-20.9, number of grains in one ear 38.7-52.2 , the mass of grains in one ear of 1.9-2.8 g, the mass of 1000 grains - 48.6-53.4. The same difference is observed in indicators of other varieties. On productivity the studied 8 varieties absolutely differ from each other. In Dedoplistskaro a variety Amandus yields the most big crop - 8.9 t/hectare, in Telavi - 6.6 t/hectare, in Khashuri - 6.4 t/hectare. Even more different results were received in case of variety Urbanus - in Akhaltsikhe - 7.8 t/hectare, in Dedoplistskaro - 6.6 t/hectare, in Telavi - 6.3 t/hectare and in Khashuri 4.8 t/hectare. On the basis of two-year researches for distribution in Georgia of the Austrian wheat varieties it can be recommended: in Dedoplistskaro - varieties Amandus, Amikus and Fidelus, in Telavi - Galuss and Lukulus, in Khashuri - Amandus and in Akhaltsikhe - Amandus, Amikus and Urbanus. The Austrian wheat varieties are the varieties of intensive type and for receiving of a big crop is required a high technology of cultivation. In the conditions of Georgia by the highest productivity differ the variety Amandus (7.2 t/hectare) and Amikus (7.1t/hectare). Tab. 2, Ref. 7.
