| Abstract: | An F7 recombinant inbred population of 234 lines (RILs) was used to extract near isogenic lines (NILs) by trait based and marker based methods. Near isogenic lines for grains per panicle and 1000 grain weight were extracted from recombinant inbred lines 65 and 197, respectively. Near isogenic lines for QTL marker locus RZ403 and interacted locus pair C1023 and C794 were also obtained from recombinant inbred lines 54 and 240, respectively. These near isogenic lines were precious genetic materials for exactly mapping QTL and studying the effects of QTL and epistasis. |
