tailieunhanh - Genetic divergence in niger (Guizotia abyssinica (L.f) Cass)

An experiment was undertaken by utilizing forty five Niger genotypes for twelve yield and yield contributing characters to assess genetic divergence. The analysis of variance has shown that there was significant variation among the genotypes in all the traits. The multivariate analysis carried out using MahalanobisD2 -statistics, indicated wider genetic diversity in the genotypes of niger. Out of ten cluster formed, cluster III was largest with twelve genotypes, followed by cluster I with eleven genotypes, cluster II and V with six genotypes, cluster VIII with five and IV, VI, VII, IX, X were mono-genotypic. The clustering pattern indicated absence of relationship between genetic diversity and geographical origin of the genotypes. | 2019 8 9 1891-1902 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 09 2019 Journal homepage http Original Research Article https Genetic Divergence in Niger Guizotia abyssinica Cass Shubhangi V.

The analysis of variance has shown that there was significant variation among the genotypes in all the traits. The multivariate analysis carried out using MahalanobisD2-statistics indicated wider genetic diversity in the genotypes of niger. Out of ten cluster formed cluster III was largest with twelve genotypes followed by cluster I with eleven genotypes cluster II and V with six genotypes cluster VIII with five and IV VI VII IX X were mono-genotypic. The clustering pattern indicated absence of relationship between genetic diversity and geographical origin of the genotypes. The maximum inter cluster distance was observed between cluster II and X D2 while lowest divergence was noticed between cluster VII and X D2 . Maximum intra cluster distance observed within cluster V D2 while lowest intra cluster distance was observed within cluster I D2 . The variance for cluster means were high for number of seeds per capitula followed by number of secondary branches per plant number of primary branches per plant 1000 seed weight number of capitula per plant and was low for plant height days to maturity diameter of capitula protein content .
