About this product

LG50639 SX Sunflower

LG50639 SX is a medium-early sunflower hybrid built for the Express Sun herbicide system across Ukraine's steppe and forest-steppe zones. It suits both intensive and classic cultivation, with a medium-intensive growth type reaching about 171 cm and an 18.2 cm head. The scorecard pairs 9/9 yield potential and stability with drought tolerance rated 8/9, so it holds performance through dry summers. Resistance to broomrape races A-G and 8/9 Phomopsis tolerance keep it clean where those pressures limit other hybrids.
