GENETIC DIVERGENCE IN CHICKPEA

Madras Agricultural Journal, 1997
Fifty genotypes of chickpea (Cicer arietinum L.) were grouped into 11 clusters using Mahalanobis's D statistic. Maximum distance was observed between the cluster VIII and XI. Plant height, number of secondary branches/plant, seeds/plant, 100 seed weight and seed yield/plant had shown more divergence among the clusters.

GENETIC DIVERGENCE IN COWPEA

Madras Agricultural Journal, 1988
The genetic divergence among seven parents and their twelve hybrids of cowpea was assessed using Mahalanobis D statistic. Ten cbaracters were studied and utilised for multi variate analysis. The genotypes were grouped into seven different clusters. The characters namely days to 50 per cent flowering.

GENETIC DIVERGENCE IN SUNFLOWER

Madras Agricultural Journal, 1996
Fifty four genotypes of sunflower were studied for their genetic divergence by D² analysis for a set of divergent characters nambely seed yield and five other metric traits. The genotypes were grouped into seven clusters. Based on the intercluster distance and cluster mean for various character.

Genetic divergence among rice strains

Theoretical and Applied Genetics, 1971
For screening better types among 10 strains with the help of the D (2) statistic, an experiment was conducted in randomized block design with three replications. 10 plants in each plot were randomly selected and observations were recorded on final plant height, heading duration, effective tillers, number of grains per panicle, yield per plant and 100 ...

Speciation, genetic divergence and palaeogeography in the hormogastridae

Soil Biology and Biochemistry, 1992
Abstract The genus Hormogaster includes a few species of earthworms, whose disjunct areas of distribution are of great interest. Three of them— H. redii , H. pretiosa and H. samnitica —occur in the region of the old granitic shield of Western Europe, and their distribution seems related to some geological events which can be dated with ...

Studies on genetic divergence in potato

Euphytica, 1978
Sixty-seven potato varieties/hybrids were grouped in 15 clusters on the basis of D2 values. The clustering pattern was not influenced by the geographic diversity of the varieties. However, a segregation between varieties of the Tuberosum and Andigena type varieties was observed.

Genetic Divergence Analysis in Tuberose

Madras Agricultural Journal, 2015
An experiment on genetic divergence analysis in tuberose was carried out at Department of Floriculture and Landscaping, Tamil Nadu Agricultural University, Coimbatore during 2012. Genetic divergence of the double type tuberose genotypes based on yield and component characters were estimated using D2 statistic.

Genetic exchange and evolutionary divergence in prokaryotes

Trends in Ecology & Evolution, 1994
Recent work shows that genetic exchange in prokaryotes is less frequent but more promiscuous than that in eukaryotes. As a result, genetic exchange plays very different roles in determining the patterns of evolutionary divergence in these major groups.

Genetic divergence in chickpea germplasm

Madras Agricultural Journal, 2000
Genetic divergence measured by Mahalanobis' D' statistics was carried out with 126 chickpea genotypes available in the germplasm pool. The varieties were grouped into seven clusters. Maximum divergence was observed in the clusters IV and VII and the minimum between the IV and V. The intercluster divergence varied from 0 to 2.99.

The genetic divergence of three populations

Theoretical Population Biology, 1987
This paper extends the study of genetic divergence in \textit{G. A. Watterson}'s [ibid. 27, 298-317 (1985; Zbl 0572.92016)] two samples drawn from two populations after the original population giving rise to them has split. The author now considers three samples drawn from three populations after the split.
