Many of the varieties of banana have been maintained locally, although in recent years the distribution of selections with improved characteristics, as well as consumer preference for defined varieties, has led to a reduction in the number of varieties grown.
The remaining 23 genotypes were distinct from previously defined varieties.
In coal, elements can be associated with the inorganic constituents (minerals) occurring as or in silicates, sulphides, oxides, carbonates, phosphates, sulphates, etc., or with the organic constituents in a variety of less well defined ways (Finkelman 1994).
By assumption, moreover, it sends the summand (Lambda _i) to itself, hence we get a well defined linear action on each Abelian variety (A'_i), so that we have a diagonal linear action of G on (A').
Both are typically well defined on a range of cases, and both display a variety of unusual logical behavior on the other cases.
Multidrug resistance (MDR), a well defined phenomenon in which cancer cells become resistant to a variety of anticancer drugs with different structures and mechanisms of action, is a major obstacle towards curative cancer chemotherapy.
A sample from the spring oilseed variety 'Comet' (A:01 haplotype) falls outside of the well defined cluster of B. napus samples, and in fact groups within the C genome cluster.
A variety of infectious models is available that involves relatively well defined target organs and host defense mechanisms; for example, infections with encephalomyocarditis virus, Herpesvirus simplex, Listeria monocytogenes, Streptococcus pneumoniae, Escherichia coli or Plasmodium berghei.
Finally it must be recognized that in many studies the sought outcomes are not well defined e.g. a number of studies report on perinatal mortality (using a variety of definitions) but do not separately report on stillbirths as outcome.
These films may grow to thicknesses in the order of 50-100 nm and contain a variety of organic and inorganic products but their structure is not well defined.
A variety of techniques is used to describe the fine structure of a series of well defined linear polyethylenes, polymerized using the new generation of metallocene-based catalysts.
