Genetic divergence in Indian mustard (Brassica juncea L.)

Abstract

Forty genotypes of Indian mustard (Brassica juncea L.) collected from the germplasm maintained at Main Castor and Mustard Research Station, Gujarat Agricultural University, Sardar Krushinagar were evaluated in a randomized complete block design with three replications during rabi season of 2001·2002. Each plot consisted of single row of 5 meter length with inter and intra row spacing of 45 em and 15 em, respectively. Ten plants were selected at random from each plot for recording observations on plant height, length of main branch, primary and secondary branches per plant, siliquae per plant, seeds per siliqua, length of siliqua, seed yield per plant, 1000-seed weight, oil content and harvest index. Whereas, days to 50% flowering and maturity were recorded on plot basis.
