Abstract:
The complex evaluation of the main maize germplasm fond
represented by old local landraces, collected 40-50 years ago, is in the
present, both in our country and abroad, opportune for the accumulation of
knowledge concerning their values for increasing of the safety and security
of agricultural production at the maize crop.
The maize germplasm used by breeders becomes more valuable when
complies with two basis conditions: genetic variability and own
performances.
The characterization of the germplasm fond represented by 200 maize
local landraces which come from different areas of Romania, was
accomplished in a complex study frame which follows two
objectives:morphophysiological evaluation for agronomic characters and
traits which are important in the wet and cold areas from
Romania;identification of some useful genetic resources for yield capacity
breeding, precocity, resistance to low temperature and resistance to rood and
stalk lodging.
The evaluation of 200 local landraces was accomplished in
accordance with IPGRI descriptors (Rome, 1996). The results of the
evaluation emphasized the incontestable value of this genetic resources for
breeding of the maize hybrids performances which are destined for
cultivation in the areas with restrictive thermal climate. Local landraces
with valuable agronomic traits such as: a good productivity, resistance to
low temperature, resistance to root and stalk lodging were identified
