摘要

A method of producing new varieties of lettuce seeds puff variety (Lactuca sativa L. var. Secalina) includes pre-treatment of seeds original forms, which hold physical mutagen action, namely the use of g-irradiation dose 15 seeds cr. In the first year the plants are grown under the scheme 70 × 20 cm, conduct individual selection of plants (seeds) On the first stage, evaluate offspring for morphological identification signs and valuable economic indicators, separation of families that include plants with distinctive from the original shape morphological signs and carrying within them the individual selections. In the III-rd stage assess individual selections allocated from the M1 generation, like the II-nd stage, the selection of the most homogeneous (constant) families with desirable characteristics corresponding model class, carrying within them the individual selections. In the IV-th stage of conducting breeding individual selection (constant families) selected in the previous step, assess and identify forms with desirable morphological features, high performance, long period of economic life (resistance to early stebloutvorennya), with high levels of biochemical structure of commodity products. In the V-th and VI-th stages of conducting a comprehensive assessment of selected promising forms corresponding model class in nursery competitive sortoispytanija by conventional techniques, optional on VI-th stage - reproduction and of individual selections of the best sortoobraztsov (at least 100 families selected samples ).
