Diversity studies among basmati and non-basmati type aromatic rice (Oryza sativaL.) genotypes for grain yield and its attributing characters

摘要

Twenty four aromatic rice genotypes were evaluated for grain yield, its attributing characters andmicronutrients viz., iron and zinc content in grains. Charactersbased on the estimated D2values as thesquare of the generalized distance 24 genotypes were grouped into six clusters by treating the. Maximumdivergence was observed between cluster III and cluster VI (D2=944.68) while, minimum divergence wasobserved between cluster I and cluster III (D2= 88.42). Cluster IV was the biggest cluster consisting ofeight genotypes viz., IET 19227, IET 19234, IET 19391, IET 19491, IET 19492, Taraori basmati, Basmati370 and Mattalaga followed by cluster III, comprised of five genotypes viz., IET 18973, IET 18981, IET18990, IET 18993 and IET 19294. The clusters I and VI contained only two genotypes viz., IET 19441 andPusa basmati; Gandhasali and Jeerigesanna respectively.
