Current environmental selection issues: selection of h. annuus l. for herbicide resistance

Abstract

This article is devoted to the creation of a new material of sunflower fertility reducing agents, having an optimal combination of tribenuron-methyl resistance and a sufficient vegetation period for the production of hybrids in zones with a short frost-free vegetation period. Lines used as a source of tribenuron-methyl resistance were purchased by Sativa LLC at the University of North Dakota Seed Fund (USA). The maximum resistance to aherbicide treatment was demonstrated by plants of hybrid combinations received by using the paternal line B0708VG, which line was significantly superior to the B0707VG line
