Genic Male Sterility1). Only a few have been induced after mutagen treatments (Table 2.3). In about 175 species in which mst has spontaneously arisen, the majority are dicots in species as well as in species crosses (Fig. 2.1). The ratio dicot to monocot is about 2.5 in induced mutants. Since the repeated appearance of

The action of . genes is cytoplasm-insensitive, whereas . gene action is cytoplasm- dependent and -sensitive as these genes act only in a certain cytoplasm type, the S-cytoplasm. This cytoplasm has specific .-genes which interact with nuclear . genes to produce mst phenotype so that only S

Chemical Male Sterilitye. The occurrence of commercially utilisable g-mst or gc-mst is, however, uncommon in economically useful plants. Accordingly, induction of mst using mutagens has been tried and a few mst’s have been obtained (Tables 2.3, 3.5), but such mutations are rare, recessive and associated with negative and

This was done by Frankel (1956), who grafted fertile maintainer scion on mst . rootstocks. Scion mft remained unaltered but mst scion progeny was recovered when scion flowers were selfed or cro

The limitation in them is negated by outbreeding, which is enforced by the development of forms having either a mixture of male and female flowers (monoecy) or of hermaphrodite and female (mst) flowers (gynomonoecy) or of hermaphrodi

Furthermore, emasculation is especially difficult in plants with small and fragile flowers. This tedium of hand emasculation is greatly obviated by using mst lines. Even with most careful emasculation, over 5–15% sellin
