Genetic analysis for yield and its components and oil content in Indian mustard [Brassica juncea (L.) Zern & Coss]

Published on

Six generations (P1, P2, F1, F2, BC1 and BC2) of six
crosses namely Pusa BasantlBio 8 (3), Pusa Basantl81,
Pusa Bahar/81, Pusa BaharlBi08(3), 113/Bi08(3) and 113/81
were evaluated for days to 50% flowering (DTF), days to
75% maturity (DTM), seed yield per plant (SYPP), thousand
seed weight (TW) and oil content (OC) in a randomized
block design under timely sown and late sown conditions.
The data of six generations were sUbjected to scaling
tests to detect epistasis and genetic parameters m, d, h,
i, j and I were estimated. Additive effects were found to
be more important in the inheritance of DTF, SYPP, TW
and OC, additive x additive for DTF, DTM, SYPP and OC,
dominance for DTM, SYPP and OC and dominance x
dominance for DTF, DTM and TW.
