For different regions of Russia a high yielding variety of white mustard has been obtained, the variety successfully combines high productivity with high seed quality and resistance to major diseases. Since 2004 it has been included in the State Register of protected varieties and approved for production ((RF patent №2651)).
Variety pedigree: the variety has been created by individual family-group selection from Hbp heterogeneous population (the Netherlands).
The botanical characteristics. The height of the plant is 96-123 cm, with a strong anthocyanin coloring. The waxy coating is strong, the stem has a strong pubescence. The width and the length of the cotyledons are average. Anthocyanin coloring of the hypocotyl is very strong, the pubescence is average.
The leaf is light green, petiole anthocyanin is strong, waxy coating is absent. The development level of the leaf segments is strong. The leaf margin serration is average. The petals are yellow. The spotting of the anther spot is absent. The flowering time is early. The pod (without the beak) is long. The beak of the pod is long. The seeds are round, large (the weight of 1000 seeds is 5,1-5,9 g), the seed color is light yellow or simply yellow.
The biological features. The vegetation period varies from 64 to 76 days. The resistance to lodging is average , seed shattering resistance is high. The susceptibility to Alternaria and Fusarium is weak - at the level of the standard (“VNIIMK 518” variety). The variety is moderately damaged by cruciferous flea beetles and rape blossom beetle.
Competitiveness. Due to its high yield potential and the quality of its seeds variety “Rhapsody” is competitive in all 12 regions of Russia.
The main advantages. With high yields, high oil and meal quality, resistance to various biotic factors, this variety is suitable for mechanical harvesting. It is recommended for cultivation of seeds and animal feed, and can be used as green manure or as a honey culture.
In the tests conducted by FSBI ARIR (2001-2003 gg.) “Rhapsody” variety had an average seed yield of 2.14 t / ha, which was higher than the seed yield of “VNIIMK 518” variety by 0.11 t / ha. The yield of green mass was 15,0 - 39,3 t / ha which was 0.02 t / ha higher than the standard. The average yield of dry mass was 2,25-5,90 t / ha - at the level of the standard variety.
Variety type "+0". The content of erucic acid in the oil is 33,3-36,8%, the content of glucosinolates in the meal is on the average 1.30% (30.4 mol / g), the content of crude fat in the seeds is 26,7-33,8%, the content of protein in the seeds is 27,8-29,5%. Essential oil level is on the average 0.17%.
The commercial value of “Rhapsody” variety is in its advantage over the standard crops due to its high seed and green mass yield, its high quality meal, its resistance to major pathogens, besides, in its technology of cultivation and harvesting. The seeds of this variety are in demand in many regions of Russia and abroad.
