PRODUCTION PROCESS OF F1 HYBRID SEEDS

摘要

The production process of F1 hybrid seeds comprises: choice of plants with a long pistil neck from a plant group exhibiting a heteromorphous self-incompatibility; isolation of the chosen plants with the long pistil neck; artificial insemination or natural hybridization with the aim to attain the hybridization determined in advance and the multiplication of the line consisting only of the plants with the long pistil neck; further artificial or natural hybridization of the line under the condition that this line remains isolated from the other lines; multiplication of the seeds to create a parent seed line, consisting only of the plant seeds with the long pistil neck; planting the parent seed line (line A) of the plants with the long pistil neck; planting another line (line B) of the plants with the short pistil neck or both kinds of plants - the ones with the short pistil neck and the ones with the long pistil neck in the vicinity of the line A; and collecting the seeds of the line A obtained after insemination with the pollen of the line B. In this way, F1 hybrid seeds have been produced during the hybridization process between the lines A and B.
