Abstract:
The purpose of this study is
to analyze the genetic progress in wheat
crop, regarding the quantitative performance
and economic aspect, the leading indicators
for measuring efficiency being: production
costs, price recovery and additional income
as the main indicators to measure the
effectiveness of genetic progress in
increasing profit / ha. In order to highlight
the genetic progress of created and approved
individual varieties, there was calculated the
quantitative contribution of new genotypes
and the results were reported to the most
representative areas for wheat production.
The quantitative genetic progress was
estimated with the help of the regression
function. The quantitative relationship
between variables, regarding the
contribution of genotypes to genetic
progress increase, quantified with the help
of coefficient (b) of the linear regression
equation, presents the following significant
values (in ascending order) for areas
analyzed: 10.62 kg/ha/year for genotypes
grown in the south in irrigated, 12.05
kg/ha/year for genotypes grown in
Transylvania, 19.26 kg/ha/year for
genotypes grown in the west and 21.25
kg/ha/year for genotypes grown in Moldova.
The approach taken justifies the context in
which the genetic research and breeding
work is a primary importance solution in
view of further increase in wheat production
in Romania. The economic results obtained
show that the newly created genotypes are
equipped with high capacity of efficient
capitalizations of areas of cultivation, the
rate of return exceeding 25% (Glosa - 32%,
Gruia - 37%, Izvor - 44%).
