ABSTRACT The international recognition of the importance of genetic diversity demands continuous estimation of genetic diversity of in hand population as test of its buffering capacity against all putative threats. Randomly selected Pakistani wheat varieties developed during 1965-1999 and 2000-2011 were evaluated on the basis of pedigree and SSR data. At 2nd and 3rd levels of pedigree, average occurrence of a parent per variety was 2.1 times. The...

Choudhury 2 Affiliation(s) 1 Department of Botany, University of Kalyani, Kalyani, India . 2 Indian Council of Agricultural Research (ICAR), New Delhi, India . ABSTRACT In this present investigation, simple sequence repeat (SSR) analysis was used to determine the genetic relatedness among 32 soybean ( Glycine max (L.) Merr.) cultivars from NRC for soybean, Madhya Pradesh. Among them 10 primer pairs showed 100% amplification. Mainly three primer pairs could amplify polymorphic SSRs from all of these cultivars. The polymorphic information content (PIC) among cultivars varied from 0.21 (S26) to 0.83 (S27) with an average of 0.51. Pairwise coefficients of genetic similarity between all genotypes ranged from 0.76 to 1.00. Unweighted pair-group method arithmetic a...
