Heterosis for Some Quantitative Characters in Brassica juncea L.

Tariq Mahmood, Muhammad Ali, Muhammad Anwar and Shahid Iqbal    

Abstract: Five cross of Brassica juncea viz., SMP 13-78 x Zem-I, SML 31E x Zem-I, DL 8 x Zem-I, SM 83000 x Zem-I, Pr 171-71 x Zem-I were made. These crosses (F1's) along with their parents were sown and heterosis was studied for branches per plant, plant height (cm), number of siliquas and yield per plant (g) in F1 generation. It was found that a cross of SMP 13-78 x Zem-I showed maximum heterosis and heterobeltotic for all the characters studied. Therefore, this cross combination can fruitfully be utilized for improving yield and its components in future breeding programmes.
