Resumen Eficiencia de distintos mГ©todos de hibridaciГіn en cruzamientos de arroz para obtenciГіn de lГ­neas puras Abstract. The phenomenon of heterosis in cereal crops is expressed mainly in the first hybrid generation (F 1).In order to utilize rice hybrids in commercial production, it is first necessary to produce a large amount of F 1 hybrid seeds. However, rice is a strictly self-pollinated crop with tiny florets, so that it is impossible to produce bulk quantities of F 1 hybrid seeds by hand emasculation.

Emasculation becomes progressively difficult as the flowers become smaller and smaller and is most difficult in the cereals where the glumes are very small and often brittle as in rice. In such plants, special techniques of emasculation are applied. Hybridization Technique # Step 3. Bagging:.

  • emasculation and pollination, it became impossible to proceed for hybridization. Hence, there is a need to standardize the techniques like suitable time of emasculation and pollination in Bambara groundnut. This need is also realized by Goli, 1997 as at IITA crosses made was unsuccessful due to EMASCULATION IN PLANT BREEDING. Emasculation involves the removal of stamens from bisexual flowers of the female parents in order to avoid self-pollination in these flowers.It is done before the anthers are mature. If in a condition the female parent bears bisexual flowers, then elimination of anthers from the flower bud before the anther dehisces by means of a pair of forceps (a large

    • Techniques of cytogenetics are useful in achieving wonderful results in plant breeding. • Now-a-days the techniques of molecular genetics are applied to save time in crop improvement.

Jun 07, 2016 · Grain amaranth was domesticated in the Americas and is highly self-fertilizing with a large inflorescence consisting of thousands of very small flowers. We evaluated three different crossing methods (open pollination, hot water emasculation and hand emasculation) for their efficiency in amaranth and validated them with genetic markers.

    The anthers should not be broken while plucking them off. Emasculation becomes progressively difficult as the flowers become smaller and smaller and is most difficult in the cereals where the glumes are very small and often brittle as in rice. In such plants, special techniques of emasculation are applied. Hybridization Technique # Step 3. Bagging: Male sterility is easy to detect because a large number of pollen grains are produced. Pollen grains can be assayed through staining techniques (carmine, lactophenol or iodine). Male sterility can be either cytoplasmic or cytoplasmic–genetic. In this case, the trigger for CMS is in the extranuclear genome - (mitochondria or chloroplast). The
