Analysis of combining ability in winter rape (Brassica napus L.) lines using diallel crosses
The analysis of general (GCA) and specific (SCA) combining abilities of 5 winter rape new lines using the method of diallel crosses was carried out. Possible ways of their further inclusion into the breeding process as components in developing F1 hybrids or line (population) varieties were determined. Detailed information on the genetic properties of the analyzed forms including the nature of genetic effects (their additivity, dominance or epistasis) which control inheritance of important traits was presented. The lines exhibiting high valnes of GCA or SCA for certain agronomic characters were revealed, and promising hybrid combinations were identified.
