叫喊

Statistical models for the detection of genes controlling quantitative trait loci expression wellaccepted aspects of the genetic control of QTs: a) “many” loci are involved, and b) the effect of the individual genes is “very small” compared to the environmental effects. Consequently, a branch of the science of Genetics concerned with quantitative traits emerged, i.e., Biometrical or Quantitative Genetics.

DNA amplification in doubled haploids of ,e methodology required for generating large numbers of haploids of most tobacco genotypes has been available for over 20 years. In addition, both colchicine (Burk .., 1972) and callus culture (Kasperbauer and Collins, 1972) techniques are available for chromosome doubling.

尊严

Self-incompatibility and pollen rejection in angiosperms plants display variations in the operation of the recognition process. In cryptogams, male and female gametes are released free into an aqueous medium and hence are in direct contact; thus recognition is dependent on the gametes themselves — no other cell or tissue being involved.

Genetic transformation of , via pollen ,overning leaf shape was reported (Hess, 1970). Furthermore, in 1969 Ledoux and Huart reported on DNA uptake into . seedlings, and some years later on the DNA-mediated correction of thiamineless mutants of the same species (Ledoux, .., 1974).

Both improved cultural practices and improved crop plants have al­ lowed us to divert more human resources to non-agricultural activities while still increasing agricultural production. Malthusian population predictions continue to alarm agricultural researchers, especially plant breeders,
