Isolated microspore culture

Study on androgenesis, highlights the feasibility of invitro haploid production in bhimkol using anthers at uninucleate stage of pollen. These haploids plants obtained could be used in conventional breeding programs to generate pure homozygous lines and auto-tetraploids in a single generation.

Sporophytic plants having gametophytic chromosome number are termed as haploid. These plants can be produced either spontaneously in nature or by in vitro or in vivo induction technique. By doubling chromosome number of haploid either spontaneously or artificially, double haploid (DH) could be produced. Double haploid are homozygous and this homozygosity is achieved in one generation by using DH production systems. This production system is used for fixation of heterosis. Genetic map construction is relatively easy with DH population.
