Genetic Analysis for Yield Components and Oil Content in Indian Mustard [Brassica Juncea (L.) Czern and Coss]

Abstract

A hne x tester analysrs rnvolvrng 8 lines and 3 testers were earned out tor 18 quanlltallve trails rn lndran mustard (8rass1ca }uncea (l) Czern Coss) Among the lrnes EC-599298 EC-385604 and EC-401 467 were appeared as best general combrners for most of the yreld contnbutong characters Whereas among the testers. Kanll was good general cornbrnes for most of the yoeld contnbutrng trarts Specrfrc combmmg abrhty effect estrmates revealed a very wide range of vanat1on for most of the characters Maxrmum sea effect rn des~rabte d~rect10n for early flowenng, plant herght, number of primary braches per plant. number of secondary branches per plant marn shoot siliquae, sllrquae per plant, marn shoot length, seeds per srhquae. srhquae length. days to maturity, brologrcal yreld, seed yreld, 1000-seed werghl, harvest rndex and oil content by the crosses EC-39930 x Kantr. EC -389298 x Varuna EC· 401467 x Kanll, EC-385604 x Urvashr, EC- 389298 x Varuna EC-386781 x Urvashr. EC-39930 x Urvashr. EC-39930 x Varuna, EC-386781 x Kanh. EC-367881 x Varuna EC-385604 x Kanll, EC- 386781 x Kanto, EC-401467 x Kanh EC· 389298 x Varuna and EC-367881 x Urvashr. respectively The cross EC-386781 x Kantr expressed maxunum relatrve heterosos (37 07 percent) and heterobeiiiOsos (17 60 percent) on desorable directron for seed yoeld Maximum Slgmficant helerobelloosos for oil content was expressed by EC· 599298 x Kanh followed by EC-39902 x Kann and EC-39930 x Kant• flower for the early maturoty cross EC-39902 x Varuna was found supenor over the others For yreld contflbubng trarts crosses EC-59298 x Kanh. EC-267881 x Kantl, EC-39930 x Kanh and EC-39902 x Kanto exhrbrted hrgher heterosis For most of the maJor characters oncludrng seed yreld both addrtrve and non ·addrtove gene achon were of prime rmportance.
