Selection for resistance to broomrape race G from segregating sunflower populations in artificial cultivation conditions

A sequence of the estimation of sunflower plants resistance to broomrape race G on artificial infestation and growing completion of resistant plants to appearing of inbreds, using greenhouses and small-size chambers Biotron-5. Four inzucht-generations had been obtained by this way for a year and two month. Three of them were constant on a resistance trait in fourth generation. The executed work showed that it absolutely possible to develop sunflower lines constant on a resistance to broomrape race G for a year and a half by consequent usage of a greenhouse and small-size chamber Biotron-5.
