TRIVALE, THE NEW WINTER WHEAT VARIETY ADAPTED TO THE LUVIC SOIL CONDITIONS

Abstract

Improving wheat for increased adaptability to luvic sol conditions in the south of the country has made significant progress lately. The sufficiently wide genetic dowry available has shown that even in the conditions of white luvic soil in the south of the territory, varieties with tolerance to aluminum ions can be obtained. The Trivale variety obtained under these conditions proved new plant characteristics, including those required by the new intensification conditions. And in this case, some gains of morphological characters were found. Their study could be useful in the constant progress of wheat improvement. From the data obtained in the two years of experimentation it was found that the length of the straw was 69-76 cm, with the thickness at the base of 3.4-3.5 mm. The length of the spike was on average 8.7-9.0 cm, and its weight was between 2.1 g and 2.4 g. The spikelets in a spike were 18.4-18.8 in number. In the spikelet, the outer glume measured 8.7 mm, the lower palea 9.7-10.0 mm, and the awns measured an average of 5.8-6.4 cm. 41.2-42.7 grains were formed in a spike, with mean weighing of 1.7-1.8 g. The grains were 6.5-7.0 mm long, 3.1-3.2 mm thick, and the mass of one thousand grains was 39-43 g. Positive correlations were generally obtained between the morphological characters. The data obtained demonstrate a progress in improving the morphological characteristics of the Trivale variety, due to the gain of a tolerance to the concentration of aluminum ions into the soil.
