COLLECTION FORMATION AND USE
Abstract
Aim. To study new collection corn accessions by vegetation period classes and its components to build up a trait collection.
Results and Discussions. The experiments were conducted in the eastern left-bank forest-steppe of
Conclusions. We grouped the lines was selected lines that are suitable for breeding:
24 lines with early emergence of seedlings (11-12 days), 29 lines with early
anthesis (49–53 days), 64 lines with a minimum gap in anthesis (1-4 days), 14
lines with rapid water yielding belonging to various ripeness groups. We
singled out cold-tolerant lines derived from a foreign (
