Diversity in three different gene pools (GP) of pigeonpea germplasm.

Na  =  No. of Different Alleles, Ne  =  No. of Effective Alleles  =  1 / (Sum pî2), I  =  Shannon's Information Index  =  −1* Sum (pi * Ln (pi)), Ho  =  Observed Heterozygosity  =  No. of Hets / N, He  =  Expected Heterozygosity  =  1 - Sum pî2, UHe  =  Unbiased Expected Heterozygosity  =  (2N / (2N-1)) * He, F  =  Fixation Index  =  (He − Ho) / He  =  1 − (Ho / He) (Where pi is the frequency of the ith allele for the population & Sum pî2 is the sum of the squared population allele frequencies), %P =  percent of loci polymorphic.
