and from the east – up to 3°40′. It is not inferior to the Bashkir populations of L. sibirica obtained from the Sonsky forestry district of the Republic of Khakassia. L. × marschlinsii exhibits a high adaptive capacity with initial origin from Great Britain. Morphological analysis of cones obtained from the settlement of Zapovednik enabled to detect a hybrid form of L. archangelica × L. sibirica with characteristics of Dahurian larch L. dahurica Laws. It should be noted that in the forest crop areas and those of collecting seeds the permissible difference between the heights above the sea level should not exceed 500–550 m.

shows that for growing high-yielding larch crops in the conditions of the Bashkir Urals
the Siberian larch L. sibirica Ledeb. and hybrid forms of these species
the cones with wide-chested forms were observed in Bashkortostan
the heart-shaped linden Tilia cordata Mill should be preferred. In the progeny of the Bashkir climate types
there is a direct relationship between the factors of geographical origin and the size of the cones
while for the Siberian progeny this relationship is inverse. With the moving of the climatic types of origin to the north and east
with allowable distances for transferring seeds relative to the area of their use approximately: from the south – up to 2°
