Despite the wide diversity of local populational and breeding varieties, the development of new varieties aimed to be improved, enhanced and to update the varietal composition of Armenian breeding. As result of breeding programs on the basis of the wheat world collection with our participation are created  5 varieties of winter wheat – ―Syunik‖,

―Kotayk‖, ―Dvin‖, ―Armik‖, ―Cristine‖, which were regionalized.

Obtained varieties are productive, of high quality and viable. Grain from all varieties has high content of crude protein and gluten, inherited by their progeny. New varieties exceed the standard variety ―Nairi 68‖ on yield productivity on 17,5-30,0%, winter hardiness on 10,4-17,9%, low stem on 1,3-13,6cm, earliness on 4-9 days, which makes expedient the cultivation of these varieties under Ararat valley conditions and in foothill zone of Zangezur region.

High-yield of new varieties during reproduction is basically caused by ear productivity. The best results on productivity parameters (ear weight and grain number, quantity of spikelets and grains per ear) were detected for ―Armik‖ and ―Christine‖ varieties, and the high content of crude protein and gluten was demonstrated by ―Dvin‖ variety (36.5 and 16.1%). Laboratory germination of new varieties in nurseries of first year testing and reproduction was equal to 98,0- 99,0% and field germination to 82,5-87,5%. The high sowing quality of seeds in the progeny was preserved.

It is planned to establish in Armenian agricultural production and to organize the primary seed growing of

―Kotayk‖, ―Dvin‖ and ―Christine‖ varieties under conditions of Ararat valley including it foothill zone and in Zangezur region; the ―Syunik‖ variety - under foothill conditions and mountain zone of country. We plan to realize the primary seed growing of wheat elite seeds of new varieties by accelerated method, that will save time and human resources.
