PRACTICAL BREEDING OF ONIONS IN PRIMORYE

Abstract

Three varieties of onions have been created and included in the State Register of the Russian Federation for the first time in the Far East at Primorskaya Vegetable experimental station – Branch of the Federal State Budgetary Scientific Institution “Federal Scientific Vegetable Center” (PVES - Branch of the FSBSI FSVC). Dmitrich: Medium. The bulb is cross-elliptical, weighing 55-70 g. Dry scales are brown, their number is 2-3, juicy scales are white with a greenish tinge. The neck of a medium-sized, two- or threepart. It have semi-acute taste. Trading yields 162-177 kg/ha. Maximum yield of 270 kg/ha (Khabarovsk region). Ivashka: Medium. The bulb is round, weighing 50-60 g, dry scales are pink, their number is 2-3, juicy scales with a pinkish tinge. It have semi-acute taste. Rocket: Medium. The bulb is wide elliptical, weighing 50-60 g. Dry brown scales, their number 2-3, juicy scales are white. It have semi-acute taste. The method of hybridization created a promising variety Antey, which is transferred to the state variety testing: early (vegetation period when sowing seeds in the soil 105-115 days). The bulb is round (index 0.9-1.1), the color of juicy scales is white. Aging before cleaning – up to 95%, keeping the storage 180 days – up to 92%. It have semi-acute taste, the dry matter content of 9.5-11.0%. Relatively resistant to bacterial rots of the bulb. For today the basic line of grades, optimally suitable for agroclimatic conditions of region which will be used for further selection with use of modern molecular-genetic methods together with scientists of Russian State Agrarian University – Moscow Timiryazev Agricultural Academy and Japanese Partners in the RNF project.
