....is hindered by the very success in collecting such a vast resource. To mitigate this problem, the core collection concept was proposed [11, 5] A core collection is a sub set (approximately 5 10 ) of the base collection. The concept is based on principles from statistical and population genetics [3]. The underlying idea is that the information gained from the core collection can be used to extract useful genes from the base collection. However, no scientific studies have yet been initiated to extract and use the information from the core collections. The objectives of this paper are: a) to ....

Sampling: An efficient, simple and robust technique for scaling.. - Addala (Correct)
.... large data sets are necessary for reliable results, large databases are not necessarily advantages for the following reasons: ffl Not all data is informative [14, 19, 15] ffl High degree of redundancy in the databases [9, 11] 2 ffl Experimental studies on the entire database are expensive [3]. This is the basic problem in genebank collections and in drug industry. For example to conduct genetic studies on a single gene we need many resources and it is impossible to conduct studies on all of the genes. So geneticists carefully sample a relevant subset of genes and conduct lab studies ....
....crop genebanks. Currently, over six million accessions of various crop species are preserved in genebanks. Paradoxically the use and management of the genebanks is hindered by the very success in collecting such a vast resource. To mitigate this problem, the core collection concept was proposed [7, 3]. A core collection is a sub set (approximately 5 10 ) of the base collection. The concept is based on principles from statistical and population genetics [3] The underlying idea is that the information gained from the core collection can be used to extract useful genes from the base collection. ....
