In the partial system of diallele crosses by Savtchenko are involved to medium late maize lines whit different origins – „Stiff Stalk Synthetic“ and „Lancaster“.
Highest general combining ability (GCA) for grain yield has the lines ФM 4618, XM 4597, XM 4558 and KC 4532. They can be used as a component of medium late synthetics as well as testers for analyze of GCA of lines in earlier generations.
Whit high SCA are the lines ФXM 4614, XM 87/136, ФM 4618 and Mo 17, which could be used directly in the heterozis breeding for developing of high yield medium late hybrids.
The best crosses are continue in concurs and ecological trails.
