- Company Profile:
The status of crops that have a narrow genetic base, which could lead to increased threat of attack from pests and pathogens. Genetically vulnerable crops have a limited number of varieties and a narrow range of genetic resistance to pests and diseases. Modern breeding has narrowed the genetic base of crops, compared with what farmers grow in traditional systems. These systems are often characterized by many different varieties, often expressing different levels of susceptibility to a given pest or disease. This heterogeneity, as opposed to homogeneity in modern varieties, reduces risk of attack by pests and pathogens.
Industry:Agriculture
The state of being genetically variable, i.e. having more than one genetic state or allele at each gene locus. Such genetically variable populations are referred to as polymorphic.
Industry:Agriculture
1). A cultivar/line used for testing the presence/absence of a gene in a given line/cultivar. 2). A pure line or hybrid known to carry one or more genes that distinctly express themselves in morphological or physiological features. The mode of inheritance of such traits is known by prior genetic experiments.
Industry:Agriculture
Change in the genetic makeup of the line, variety, or hybrid if grown over a long period particularly in areas outside their adaptation.
Industry:Agriculture
An institution concerned with the collection, conservation, and utilization of germplasm.
Industry:Agriculture
Germplasm that includes the entire array of cultivars in the crop species, related wild species in the genus, and hybrids between the wild and cultivated species.
Industry:Agriculture
The production of progeny that derives some of its genes from one parent and some from another genetically different parent; as a result, the combination of genes in the progeny is different from that of either of the parents. In higher organisms, recombination occurs by way of independent assortment or crossing over; in lower organisms, it occurs by way of transformation, conjugation, or transduction.
Industry:Agriculture
Trueness to type; seeds or plants genetic potential. The likelihood that the genetic material (improved or primitive) is capable of producing many new genotypic combinations from stored variousness by hybridization and subsequent segregation, recombination, and selection under varying pressures conforming to the characteristics of the variety, line, or hybrids.
Industry:Agriculture
The likelihood that the genetic material is capable of producing many new genotypic combinations.
