Induction of androgenesisin vitro in various genetic forms ofSecale cereale

Six thousand anthers ofSecale cereale cv. Dańkowskie Zlote and inbred lines L214 L215 and L258c/5, in the uninuclear microspore were cultured over a period of three months on Murashige and Skoog nutrient medium supplemented with IAA (1–2μg1−1), kinetin (0.2 to (1.0μg1−1) and 2,4-D (0.5–2.0μg1−1). First divisions of microspore were observed after 7 days. In the course of 10 weeks, 4 albino tic embryos at the cotyledon stage were observed that died away in the course of further culture. The course of androgenesis was regular in inbred lines and irregular in rye cv. Dańkowskie Ziote. The efficiency of androgenesis and the amount of observed globular structures in anthers were also dependent on the genetic potency of the material. Inbred lines did not show any greater viability of embryos.
