Ceballos, H.Sánchez, TeresaChávez, Alba L.Iglesias F., Carlos ArielDebouck, Daniel G.Mafla, G.Tohme, Joseph M.[Variation in crude protein content in cassava (Manihot esculenta Crantz) roots]Variation in crude protein content in cassava (Manihot esculenta Crantz) roots

Cassava (Manihot esculenta Crantz) is one of the most important sources of starch in the tropics. There is limited and contradictory information regarding cassava starch characteristics. The International Center for Tropical Agriculture (CIAT) holds in trust FAO's cassava germplasm collection. St...

For many crops with preferential vegetative propagation, or which are sterile, or have seed unresponsive to standard seed storage techniques, in vitro methods can provide a valuable adjunct to other germplasm conservation strategies. Two types of in vitro gene banks are proposed: (i) an in vitro ...

Shoot tips of in vitro-grown plantlets of cassava (Manihot esculenta Crantz), representing a wide range of germplasm, were cryopreserved as follows: precultured for 3 days, cryoprotected and dehydrated for 1 h, then frozen in liquid nitrogen using a six-step protocol. After 3 h in liquid nitrogen...


Escobar Pérez, Roosevelt H.Mafla, G.Roca, William M.[A methodology for recovering cassava plants from shoot tips maintained in liquid nitrogen]A methodology for recovering cassava plants from shoot tips maintained in liquid nitrogen

Cryopreservation in liquid nitrogen of isolated zygotic embryos and whole seeds of cassava have been studied. A simple method is proposed for utilization in germplasm conservation or other related uses. Very high percentage survival values (ca. 97 percent) of zygotic embryos and whole seeds were ...
