In a survey carried out in 2016 and 2017 an Generall and Specific Combining
Ability for grain extraction capacity was assessed for a set of medium-early maize
lines, part of the Corn Collection of Maize Research Institute –Knezha.
Highest GCA from the studied lines have КС 12 8, КС 12 14, КС 12 7 и КС 12
13, which are recommended in the breeding programs for creating a high-yield ness
synthetics.
With highest SCA are the lines КС 12 4, ХМ 1311, КС 12 6 и КС 13 59, which
could be used in the heterosis breeding for developing of a high productive hybrids
combinations.
