Combining ability (SCA & GCA) and heterotic response analysis in Indian mustard ( Brassica juncea L. Czern & Coss)

Abstract

The analysis of variance for combining ability were found significant for all the characters. The variance among males, females and due to interaction between males and females were found highly significant for all the characters. The line namely; Varuna, Maya, Ashirwad, NDR-8501, Pusa Bold and Pusa Bahar were found good general combiners for all the characters. The cross combinations namely; Varuna x RK-9808, Pusa Bahar x Mathura Rai, NDR-8501 x RK-9807, B-85 x Mathura Rai, Urvashi x RK-9808 and Pusa Bold x Mathura Rai were found good specific combiners and showed positive heterotic response for all the characters.
