Evaluation of sunnhemp (Crotalaria juncea) genotypes for high fibre yield

Abstract

Four genetically different genotypes of sunnhemp (Crotalaria juncea L.) were evaluated for fibre yield and its yield component traits for three years 2008-2009 to 2010-2011 at Sunnhemp Research Station, Pratapgarh, Uttar Pradesh. Significant differences among experimental genotypes were recorded for fibre yield and its attributes. High fibre yield/ha was recorded for SUIN-029 (9.06 q/ha) followed by SUIN-80 (8.94 q/ha). The highest green biomass yield (337.30 q/ha) and stick yield (52.41 q/ha) were recorded for SUIN-029. The analysis of the data for all years revealed superiority of genotype SUIN-029 for most of the fibre yield traits. This genotype can be used as donor for future breeding programme.
