INHERITANCE OF QUALITATIVE TRAITS AND THEIR LINKAGE IN BLACKGRAM [VIGNA MUNGO (L.) HEPPER] MUHAMMAD ARSHAD*, ABDUL GHAFOOR AND AFSARI SHARIF QURESHI**
Abstract:
Four parents (Mash 1, Mash 3, MM 33-40, and 45726) were used to study
inheritance of four qualitative characters, i.e., pubescence, seed coat
colour, presence of spots on the seed coat and pod colour. All the four
traits revealed monogenic nature of inheritance segregating in Mandelian
ratio (3:1). The hairiness pattern was observed dominant over non-hairiness;
brown seed coat colour dominant over green seed coat colour. Presence
of spots on seed coat was dominant to absence of spots and black pods
were dominant over brown pods in blackgram. Out of three hybrids, two
(Mash 1/MM33-40 and 45726/MM33-40) revealed linkage between pod colour
vs presence of spots on seed coat and pod colour vs seed coat colour
that is suggested to be used for preliminary mapping in blackgram.
