An evaluation of germplasm accessions in Guar (Cyamopsis tetragonoloba L.)

Abstract

300 germplasm accessions of guar (Cyamopsis tetragonoloba (L.) Taub) were evaluated for a number of component characters including yield. A study of heritability, expected genetic advance and phenotype correlation coefficients suggested that there was ample scope for testing some of the stocks in yield trails and exercising selection for these traits simultaneously. One of the accessions was promising in yield with field resistance to bacterial blight as well. Some of these accessions are under further evaluation directly and in breeding programmes to improve seed yield.
