Four different sets of partial diallels were analysed for their relative efficiencies for estimating the genetic parameters in barley: (1) partial diallel with 12 parents, each involved in only 5 crosses; (2) partial diallel with 12 parents, each involved in only 3 crosses; (3) partial diallel with
Four exotic and four indigenous strains of barley were used for making diallel crosses. The sets of parents and crosses making full, half and quarter diallel were analysed in a randomized block design for plant height, number of effective tillers, ear length, grain yield per plant, 100 grain weight
Electrophoretic assays of 1506 accessions of domestic (Hordeum vulgare L.) and wild (H. spontaneum Koch.) barley, maintained in the USDA World Barley Collection, led to the following conclusions: (1) worldwide the four esterase loci, Est 1, Est 2, Est 3, and Est 4, have a minimum of 7, 12, 6, and 7
