METHOD OF PRODUCING TRICALE HYBRID SEEDS Russian patent published in 2005 - IPC

FIELD: agriculture, in particular, plant selection, may be used for creating of hybrids.

SUBSTANCE: method involves sowing; pollinating gelded ears with tricale pollen under isolation conditions and growing to maturity state; sowing winter and autumn sorts of tricale over coulisse-strip fallow, winter sorts being sown at three periods: first period including time traditional for concrete zone, second period including three-leaves stage of first period plants and third period including time before winter stage of first period plants, and autumn sorts being sown at two periods simultaneously with second and third sowing periods for winter sorts; during pollination of tricale ears with tricale pollen, providing direct and reverse crossings of sorts of one winter type of development as well as of different winter and autumn sorts; using group isolators for isolating of gelded ears, with at least 30 ears being gelded in each hybrid combination.

EFFECT: provision for extended hybridization period and production of greater amounts of hybrid seeds.
