Embryo rescue, also known as embryo culture, is an in vitro technique frequently employed in horticulture crops to save hybrid results of fertilization that would otherwise deteriorate. In embryo culture operations, the artificial nutrient medium replaces the endosperm, allowing the embryo to continue developing. Laibach demonstrated the first successful embryo culture to produce an interspecific hybrid between Linumperenne and L. austriacum. Several improvements have been achieved since then in embryo culture/embryo rescue procedures, which have been a popular approach for generating hybrids from a variety of incompatible crossings. Currently, embryo rescue shows enormous promise not just for wide crossings, but also for producing plants from essentially poor embryos, producing haploid plants, and shortening the breeding cycle. This review presents application of embryo rescue that is being used in Solanaceae crops for overcoming different interspecific pre- and post-barrier which is important resistant to different abiotic and biotic stresses.

In this study, we survey the literature regarding methods used to prevent embryo degeneration and to obtain viable interspecific plants from embryos. In spite of the fact that embryo rescue has not been used in many field trials, and how much plant material of agricultural and horticultural value has actually been generated. There is a large potential for rescuing desired embryos that would otherwise degenerate with the embryo rescue technique, as it is simple to use and possesses a wide range of potential applications. A plant tissue culture laboratory usually has the necessary facilities for this technique. Nevertheless, certain constraints are relevant under suboptimal conditions. On other hand, perennial plants are easier to handle as they can be kept in laboratories, transplanted at any time of the year, and acclimated until they become hardy enough to survive in nature or domestication.
