Effects Of 2-Chloroethyl-Phosphonic Acid (Ethephon) As A Male Gametocide For Induction Of Sterility In Wheat And Barley, Jacqueline Taylor Martin

Doctoral Dissertations

Exploitation of induced male sterility has now become a potential tool in plant breeding. Ethephon (2-chloroethyl-phosphonic acid) has induced male sterility in winter cultivars of wheat and barley.

The purpose of this research was to further elucidate the response of winter wheat (Triticum aestivum L. em Thell), and winter barley (Hordeum vulgate L.) to foliar application of ethephon.

Ethephon was foliarly sprayed on winter cultivars of wheat and barley which were Arthur and Blueboy, and Barsoy and Volbar respectively, at 0.05, 0.10, and 0.20 and 0.40 percent active ingredient, when plants were in mid-boot and late boot stages in the …
