Stability of fibre yield and its component traits in tossa jute (Corchorus olitorius L.)
Stability study for fibre yield and its attributing traits was carried out in six tossa jute (Corchorus olitorius L.) genotypes including two checks under four different ecological conditions of India over two consecutive years 2005 and 2006, I under All India Network Project on Jute and Allied Fibres. Six experimental entries in AVT-I and AVT-II responded differentially to the different environments as evidenced by their non significant difference for the different traits in the different environments. On the basis of the stability parameters Wi (Wricke’s Ecovalence) and Di (Hanson’s genotypic stability) the genotype JRO-524 (standard check) was identified as stable for fibre yield and its attributing traits over the environments. It was followed by the genotype CO-56 with high fibre yield and moderate Wi (%) and Di values. These two genotypes were identified to be suitable for high input conditions of cultivation.
