For the conditions of the Northwest and Volga-Vyatka regions of Russia a variety has been created which combines high productivity potential , high quality seeds , considerable resistance to main diseases. Since 2012 it has been included in the State Register of protected varieties (RF patent number 6384) and approved for production.
Variety pedigree: The variety was obtained by hybridization of LK-034-00 x Casol varieties.
Botanical characteristics. The plant is of the average height 90-119 cm. There is no anthocyanin coloration on the stem. . The maximum width of the cotyledon is average. Hypocotyl anthocyanin coloration is mainly average. The leaves are green with no anthocyanin, the length and width are average. The waxy coat on the upper side of the leaf is weak or medium. The number of segments is small or medium. The length of the stem varies from medium to long. The leaf segment development is weak or average. Leaf margin serration is moderate. The petal is yellow, the length and width indices are average. The anther spotting is very weak. The flower stalk is of a medium length. The flowering time is average. The pod length (without the beak) is average. The pod beak length is average. The seeds are round and black. 1000 seeds weight is 3.0-3.5 g
Biological features. The variety is mid-ripening , its vegetation period is 90-97 days. The lodging resistance is above the average, seed shattering is average - 0.3 higher than the standard (Ratnik variety).
The susceptibility to Alternaria and Peronosporales is high, to Fusarium, is average - at the level of the standard. It can be averagely damaged by cruciferous flea beetles and more seriously damaged by rape blossom beetle.
Competitiveness. Due to spring rape high productivity potential and seed quality “Atlant” variety is quite competitive in the Northwest and Volga-Vyatka regions , where this variety has been added to the State Register and approved for the use in production.
Main advantages. High yielding with the high oil and oilseed meal quality, this variety is technologically oriented for mechanical harvesting and is recommended for cultivation for seed and fodder purposes. It can also be used for green manure.
During the field trials (CSI 2006-2009)conducted by FSBI ARIR the seeds of that variety had a production level of 2.27 t / ha, which is higher than the standard (Ratnik variety) by an average of 0.29 t / ha or 14.7%. The highest seed yield of 3.73 t / ha was obtained in 2010 on «Sloboda» State seed-trial ground in Kirov region.
Variety type "00". The oil has practically no erucic acid , the content of glucosinolates in the seed is 0,45-0,81% (10,5-18,9 mmol / g). The content of crude fat in variety seeds is 40,9-43,0%, protein - 22,2-25,6%.
The commercial value of «Atlant» variety is its high seed yield, high oil and seed quality, its resistance to main pathogens, these indices are higher than those of the standard variant, and its cultivation and harvesting technologies are also preferable.
