The study on the cultures of various explants,including mature embryos, derived from 6 cultivars of wheat indicated that the explant with the highest regenerative capacity was mature embryo,following by young spike, stem node,young leaf and seedling root tip.The mature embryos were found to be the suitable explants in tissue cultures of wheat,since their regenera- tive potential was higher than that of others,the rate of callus induction was above 900%,the frequency of plant regeneration from the callus rea...
