Title
To perfect selection methods of timothy for creation of crones for the polycross hybridization and, based om them, cleate a new variety with the intensive spring growth and dry matter yield 11 – 12 t/ha, seeds 0,5– 0,6 t/ha for the zone of the Polesie and Forest – steppe.

The object of study - the selection of Lugo timothy (Phleum pratense L.). The purpose of research - based on improved methods of breeding timothy grass to create clones for polikrosnyh crosses withdraw and transfer to the state variety testing variety with intense type of spring growth and yield of dry matter 11-12, seed 0.5-0.6 t / ha for the conditions of Polesie and forest-steppe. Research methods - polikros with comprehensive exploration of clones with high general combining ability (ACS). Selection work on the creation of new varieties of timothy archery is held on the full selection scheme. Starting material was prepared by the method of reciprocal hybridization using varieties of different ecological and geographical origin. The main results for 2013: in 4 blocks of competitive variety trials timothy grass on dry matter productivity significantly exceeded the standard (grade Pirnivchanka, Vyshgorodska, Karina, Argenta) numbers of RP-16 Milena 0.82 t / ha (12.1%) , RP-1, RP-3 and PR-14 - 0.7 t / ha (10.6%), RP-11 and RP-12 - 0.3 t / ha (4.5%) for productivity last 6.6 t / ha. With these numbers on the stability of increases dry matter over the years is the best number RP-16 Milena. Sort timothy Milena average for 6 (2006 - 2013 pp.) Years exceeded the standard (grade Argenta) 1.3 t / ha (11.2%) at the last harvest of 11.6 t / ha of dry matter.
