Genetic diversity in plants 73 of correlations between genetic variation and environment which could sensibly be interpreted as resulting from what Turesson (1922) called a genotypical response to habitat.

In genetic diversity studies, the most frequently used markers are microsatellites.

Therefore, it is necessary that restoration aims at achieving high genetic diversity of plant populations in addition to the recovery of characteristic species composition and diversity. e assessment of EST-SSRs in genetic diversity analysis was done among plants belonging to distinct groups comprising cereals, Saccharum related genera, Saccharum species, and Saccharum cultivars.

Summary measures of genetic diversity in cultivated plants and their wild relatives are needed to guide managerial decisions, to monitor progress and to warn of emerging problems in agricultural production. Several methods for estimation of ge- netic diversity using molecular markers are available. Reciprocal recombination arises via the exchange of genetic information between two nonsiscer chromatids.

Ahmad Naseer Aziz. Inter simple sequence repeat (ISSR)-PCR is a technique, which involvesthe use of microsatellite sequences as primers in a polymerase chainreaction to generate multilocus markers. Genetic diversity is the variation occurred in genetic information, which depends on frequency and diversity of alleles among individuals within a population or a species. plants on microbial communities in soil have been reported, they were mostly the result of differences in geography, temperature, ... that crop genetic diversity will decrease because breeding pro-grams will concentrate on a smaller number of high value culti-vars.
