An investigation was worked out at experimental Research Farm of Agricultural Research Station, Badnapur during Kharif, 2022 to study the genetic pattern of seed coat colour and pod colour and their joint segregation pattern in F1, F2, BC1 and BC2 of two crosses among three parents which differed for these traits. The seed colour determines the seed quality as well as market value. The analysis for inheritance studies for crosses having green x yellow seedcoat and black x yellow pod parental combination showed green seedcoat, black pod colour dominant over yellow seedcoat and yellow pod respectively. The joint segregation test for seedcoat colour and pod colour in F2 and backcrosses revealed independent segregation to each trait and may advances to use as morphological markers individually for different genetic studies as well as to estimate rate outcrossing in greengram. The seedcoat colour and pod colour exhibited monogenic control which can be further used to exploit in mungbean improvement programme.

In conclusion the seedcoat and pod colour in cross BM 4 x BM 2019-12 and Kopergaon x BM 2019-12 was found under control of dominant gene with monogenic gene action. The monogenic control of these traits can be used to exploit in mungbean improvement programme.
