Satellite Symposium 5: Molecular Breeding
Description
Tall fescues (Festuca arundinacea Schreb.) are cool season forage and turf grasses of significant agricultural importance in different grassland countries. Genetic improvement of tall fescues by conventional selection procedures is slow, since these are predominantly, cross-pollinated, hexaploid and generally infertile (Jauhar, 1993). Genetic Engineering approaches for incorporation of agronomically useful traits may contribute to the development of improved tall fescue cultivars (Spangenberg et al., 1998). However for any genetic engineering studies, it is essential to develop a genotype-independent, reproducible and efficient in vitro plant regeneration protocol. In the present study, we analyzed the effects of different sterilization procedures for in vitro seed germination and studied the effects of different concentrations and combinations of 2,4-D and BAP on callus induction, growth and regeneration potential of two cultivars of tall fescue.
