❤. POLYEMBRYONY ❤
⭐. Production of more than one embryo in a seed is called poly embryony.
Ex: Citrus and Mango.
⭐. These embryos are the apomictic embryos
⭐. Cultivation of hybrids has tremendously increased productivity.
⭐. One of the problems of hybrids is that hybrid seeds have to be produced every year.
⭐. If the seeds collected from hybrid plants are sown , the plants in the progeny donot maintain hybrid characters.
⭐. Production of hybrid seeds is costly and too exepnsive for the famers.
⭐ If these seeds hybrids are made into apomictics there is no sggeregation of characters in the hybrid progeny .
⭐. Then farmers can keep on using the hybrid seeds to raise new crop year after year and he does not have to buy hybrid seeds every year.
