AbstractIn this critique it is argued that the genetic basis of the evolution of resistance is dependent on how the phenotypic, and underlying genotypic, variation is channelled during a selective response. A polygenic response is preferentially favoured if selection acts within the phenotypic distribution of susceptibles; a monogenic response is predicted if selection screens rare mutations with phenotypes outside that susceptible distribution. The relevance of this model to the method of genetic analysis, the prediction of resistance mechanisms to novel insecticides, the generation of resistant beneficial insects and the development of the most effective resistance and integrated pest management programmes is discussed.

Earlier studies of the processes leading to flowering in spring wheats have been extended to embrace a genetic analysis of photoperiodic sensitivity in several spring varieties. The American variety Thatcher proved particularly sensitive to the short days experienced in the greenhouse during the winter months. Compared with Selkirk, Thatcher is later under short days, and this lateness appears to be conditioned by a second minor gene over and above that already recognized in Selkirk. The backcrossing procedure has been used to establish two new recombinant genotypes intermediate in behaviour between the parental varieties Triple Dirk and Thatcher. Abnormalities in ear development of sensitive varieties like Thatcher were consistently produced when plants raised under short days were transferred to long days soon after the estimated time of initiation of floral primordia.
