Breeding and Population Research in Rice

Jackson, Mre

Rice (Oryza sativa) is that the initial crop with order sequenced. Within the past decade, thousands of rice accessions within the germplasm banks worldwide are genotyped and various rice variation databases are made. one amongst these information’s is that the rice variation database (RVD; http://variation.ic4r.org/), a female offspring information of the knowledge Commons for Rice syndicate (IC4R). RVD may be an assortment of eighteen million single ester polymorphisms (SNPs) known from 5152 rice accessions supported whole-genome sequencing knowledge, associated offers an ultrahigh-density rice variation map, with regarding one SNP per twenty bases on the average. the knowledge contained during this high volume of raw SNPs isn't prepared to be used till it's been processed to get rid of low-quality SNPs, like those with missing/lowfrequency genotypes, or redundant SNPs known because of linkage situation (LD). additionally, differing types of analysis activities need totally different magnitudes of SNPs to confirm economical computation and correct results. as an example,
