Chapter 14 - Polyploids, Haploids, and Mutations

We are concerned here with major changes in genetics of pines brought about by natural or artificial changes in chromosomes and genes. Crossing within or among species results in a new combination of genes which gives rise to distinctive types of trees, but there are no changes within the genes themselves. We are also concerned with reviewing the nature and amount of natural variants and, in addition, the methods for and results of attempts at artificially creating mutants and polyploids. These are discussed in relation to the importance of mutagenesis in creative breeding with southern pines.
