The economic efficiency of genetic progress for the winter wheat varieties approved in Romania during 2000-2010

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%).
