Biotechnology in Rice Improvementltas of the great rivers of Asia. It feeds more than half the world’s population. About 90% of the world’s rice is grown and consumed in Asia, where it contributes about 50% of dietary energy (Juliano 1985). Rice is also a staple food in Latin America, parts of Africa, and the Middle East.

Genetics of Hybrid Sterility in Wide Hybridization in Rice (, L.)lity is also found frequently in homozygous progeny lines from wide crosses (Kitamura 1961, 1962; Oka and Doida 1962; Yokoo 1984). As covering whole aspects of sterility problems is beyond the scope of this chapter, semi-sterility in the heterozygous state will be dealt with here.

Hybrid Rice in China — Techniques and Productionhat it is impossible to produce bulk quantities of F. hybrid seeds by hand emasculation. This is the primary reason why heterosis in rice has not been utilized in commercial production. To solve this problem, the most effective way, as proved by other self-pollinated crops, is to exploit the phenomenon of cytoplasmic male sterility.

Endosperm Culture and the Regeneration of Triploid Rice Plantswever, by the in vitro culture of endosperm they can be obtained in a matter of weeks (Bajaj et al. 1980). Moreover, endosperm-derived plants would generate somaclonal variation and will add to the genetic variability in this important cereal crop (Bajaj and Bidani 1986).

Early Events in Somatic and Zygotic Embryogenesis in Ricep as bipolar structures, eliminating the need for separate root- and shoot-forming media during regeneration. Also, by virtue of a presumptive single cell origin, the possibility of chimeric regenerants is reduced and the potential for obtaining identical, genetically engineered plants from manipulated cells or protoplasts can be realized.
