PISUM SATIVUM SEED PRODUCING TECHNOLOGY

The basic theoretic methodology for producing seeds of autogamous cultivars is conservative selection, which is a combination of simple individual selection and mass selection. Unlike using these methods in plant improvement, the conservative variant of the selection used in producing seeds is meant to preserve unaltered the genetic structure of the cultivars as long as they are being cultivated. Starting from this central objective, methodological schemes developed for the production of seeds of different autogamous cultivar types are rather similar, the differences residing in the prolongation of shortening of the conservative selection process in order to maintain unaltered the genetic structure of each type of cultivar apart. In producing seeds of the pure lines” parental forms and of the commercial hybrids the methodology appeals not only to selection but also to self-pollination, SIB cross-pollination and line guided hybridising.
