Breeding for combining yield and fibre quality in white jute (<i>Corchorus capsularis</i> L.) accessions
Keywords:
Combining ability, High yield, Fibre strength, Fibre finenessAbstract
Diallel crosses were made among eight parents with high yield potential, good fibre quality, and resistance to biotic and abiotic stresses. Twenty crosses showing high F1 mean, high gca and high gca effects for one or both parents were identified and carried forward by modified bulk method for selecting transgressive segregates. A micro plot trial was conducted with four best F7 lines along with two checks. Fibre yield, fibre percentage, and stick weight of all the four lines were higher than that of the checks. Analysis of variance revealed that differences in plant height, fibre yield, stick weight, and fibre percentage were significant. Line 2 derived from the cross combination CIJ 072 × CEX 045 was the best performer with regard to fibre yield, stick weight, and fibre % followed by line 1 derived from JRC 698 × CIJ 121. All four lines had fairly good fibre strength and fineness.Downloads
