Combining abilities and gene effects on sunflower grain yield, oil content and oil yield

摘要

Background and Purpose: The purpose of this research was to estimategeneral (GCA) and specific combining ability (SCA) for grain yield, oilcontent and oil yield of sunflower inbred lines, to estimate the portion of ge-netic and additive component of variance, to determine relationships be-tween inbred lines, two-line (SC) and three-line hybrids (TWC), and to de-termine perspective parental lines and hybrids.
