Abstract
A 8x8 complete diallel population was studied to estimate correlation coefficients of seven quality and morphological traits
in wheat. Sowing was done on 15th November and 15th December 2007-08. The differences among all the traits were
statistically significant. Grain yield per plant under normal planting was significantly and positively correlated with plant
height, peduncle length and 1000-grain weight. It was also positively correlated with spike length and gluten at genotypic
level at P≤0.01. Only grain yield per plant was negatively and significantly correlated with protein under both planting dates
at genotypic level. Genotypic correlation of grain yield per plant in case of late planting was positive and non-significant with
plant height, peduncle length and spike length, while it was negatively correlated with gluten. Phenotypic correlation of grain
yield per plant with plant height, peduncle length, spike length, 1000-grain weight and gluten was positive and significant
under both plantings while grain yield per plant was negatively and significantly associated with protein. It is therefore
suggested that 1000-grain weight, peduncle length and gluten should be given more emphasis to improve yield and quality in
wheat.
