Evaluation of the breeding value of the spring oilseed rape (Brassica napus L.) inbred lines based on a multi-trait analysis

Abstract

Oilseed rape (Brassica napus L.) is the most important oilseed crop after soybean worldwide, especially in the countries with moderate climate. The aim of the present study was to assess the genetic crossing potential of eight inbred lines of the spring oilseed rape (B. napus L.) based on the indices of associative combinatory value. The main trait for calculation of multidimensional indices of genetic potential was the seed yield per plant. Obtained results showed that the selection index can enable the choice of the most valuable lines to be practically used in heterotic breeding of the oilseed rape.
