HETEROSIS IN CROSSES OF INBRED LINES OF RATS

Heterosis in crosses of inbred lines of Duroc swine.

B ETWEEN 1938 and 1949 seven different unrelated inbred lines of Duroc swine were developed by the Oklahoma Agricultural Experiment Station in cooperation with the Regional Swine Breeding Laboratory. In sixteen of the twenty-two farrowing seasons from the spring of 1939 through the fall of 1949, both inbred and two-line-cross litters were produced. In some seasons outbred Duroc and three-linecr...

QTL Mapping of Combining Ability and Heterosis of Agronomic Traits in Rice Backcross Recombinant Inbred Lines and Hybrid Crosses

BACKGROUND Combining ability effects are very effective genetic parameters in deciding the next phase of breeding programs. Although some breeding strategies on the basis of evaluating combining ability have been utilized extensively in hybrid breeding, little is known about the genetic basis of combining ability. Combining ability is a complex trait that is controlled by polygenes. With the ad...
