Abstract
The history of modern wheat and its relation with ancestral species have remained major concern for the evolutionist. Evolutionary path of wheat ancestors and modern wheat were studied using phenotypic data pool. Twenty three wheat species including ancestral and modern species were characterized for basic traits. Replicated phenotypic data on panel of 23 species were recorded, analyzed, pooled and dendrogram was developed. The clustering of species divided the 23 species into two main groups A and B. Group A contained four species Aegilops biuncialis, Aegilops ovata, Aegilops vavilovii and Aegilops variabilis. The group B consisted of 19 species. Group B had four sub clusters. First sub-cluster had Triticum monococum, T. polonicum, Hordeum vulgare-1, H. vulgare-2 and T. compactum. Second sub-cluster had T. durum, T. sphaerococum-1, T. sphaerococcum-2, T. sphaerococcum and T. aestivum. Third sub-cluster had T. dicoccum, T. spelta, T. dicoccoides and Triticale. Fourth Sub- cluster had T. turgidum-1, T. turgidum-2, T. turgidum-3, T. turgidum-4 and T. turgidum-5. The species in the same sub cluster such as of sub-cluster-1 were more similar to each other compared to other sub clusters viz., 2, 3, 4 and 5. Hence modern wheat i.e., Triticum aestivum is lying in sub-cluster 2 in the group of Triticum sphaeroccocum and Triticum durum species. The findings showed that Triticum durum has lineage of ancestral history with modern wheat. Exploration of evolutionary path of modern wheat Triticum aestivum L., will be helpful in successfully improving wheat crop for various diverse traits
