New sea-buckthorn variety Agronomicheskaya 70 for the Baikal Region

Abstract

Long-term studies on the development of a new sea-buckthorn variety Agronomicheskaya 70 for the Baikal region are discussed. The research goal was to develop a highly winter-hardy, slightly thorny variety with a yield of 12 t ha, a fruit weight of 0.9 g, dense pulp, dry tear-off, high content of biologically active substances, and suitable for mechanized harvesting. The sea-buckthorn variety Agronomicheskaya 70 was obtained by analytical selective breeding. Its assigned accession number is 2-3-09. The parental forms: Turanian × male form of Tunkin ecotype crossed in 2009. The variety authors are Vasileva Natalya Aleksandrovna and Guseva Nadezhda Kondratevna. The activities on the development of a new sea-buckthorn variety Agronomicheskaya 70 was carried out from 2020 through 2024. The shrub is medium-high, medium-spreading, and the height is up to 1.5 m. The leaves are medium-sized, dark green. The fruits are large, round-oval, orange-red, the skin is of medium thickness, berry nappiness is weak, simple. Fruits are sweet and sour, aromatic, and delicate. The general condition of the new variety Agronomicheskaya 70 during the years of research is evaluated as high. The average berry weight is by 0.1 g higher and amounts to 0.6 g. The transportability of berries is medium. The variety is a multipurpose one. The berries of the Agronomicheskaya 70 variety contain the following: dry soluble substances - 12.8%; sugar - 10.6%; vitamin C - 276 mg%; acids - 1.3%; sea-buckthorn oil - 9.2%; carotene - 8.8 mg%. The tasting score of fresh berries is 4.8 points. The variety is suitable for the following types of processing: jam, natural juice. Based on the results of the long-term research, the new sea-buckthorn variety Agronomicheskaya 70 will be transferred to the State Varieties Testing.
