Establishment of an in vitro haploid production system for aromatic rice cultivars of Assam

Abstract

Production of haploid plants from immature pollen grains offers a good technique for rapid development of homozygous lines and early release of new crop varieties. For induction of haploids, the most promising and successful system is microspore androgenesis (culture) within or in isolation from the anther. For successful haploid production, it requires establishment of an efficient and reproducible regeneration system which is lacking for the local cultivars of Assam. In the present investigation, we could optimize the in vitro haploid production system technique suitable for aromatic rice cultivars of Assam.
