The wide geographical distribution of the rice
plant ( Oryza sativa L.) and its long history of
cultivation in Asian countries have led to the development
of a great diversity of varietal types.
Similarly, workers in various rice-growing countries
use different terms to designate identical
morphological and physiological characters, agronomic
traits, gene symbols, and cultural practices.
Whereas varietal diversity in germ plasm is desired
in rice breeding, variations in nomenclature hinder
scientific communication among the workers.
Research objectives: Supplement and complete a biodata and production technics of a native species with high economic values; the findings of the study are references for future researches, curriculums, technical officers, advisors and students; the study is also expected to build a technical guidance for producing Phay’s seedlings contributing to development andproduction of Phay, a native large-timber species, in Bac Kan province and other provinces with similar natural conditions.

Prenatal diagnosis, traditionally used as a synonymous for invasive fetal testing and
evaluation of chromosomal constellation, presently encompasses many other issues like
pedigree analyses, fetal risk assessment, population screening, genetic counseling and fetal
diagnostic testing as well. Ultrasound guided chorionic villus samling (CVS), amniocentesis
and, to a lesser extent, fetal blood sampling are used routinely in fetal medicine units. Other
fetal tissue biopsies such as skin, liver and muscle biopsy are used only rarely.
