Genetic stability analysis and molecular depiction in elite entries of rice (Oryza sativa L.)

Abstract

from genetic stability analysis where they were recorded as high yielding; in addition, positive data for the remaining traits studied under the 12 environmental conditions were tested. Line numbers 1, 3, 4, and 5 were in the first rank for high genetic stability and high stable yielding under all experiments, while line numbers 2, 6, and 7 were recorded in the second rank. The values of broad sense heritability were very high in some traits (plant height, heading date, number of filled grains/panicle, grain yield/plant, and flag leaf area) which indicated that the genetic variance played an important role for controlling and inheriting these traits. A total of 101 fragments were generated using six primers of ISSR through comparison among the seven rice lines, where 34 of them were monomorphic and 67 bands were polymorphic with 66.33% polymorphism.
