| Abstract | ||
| Five sorghum varieties (Milo, Kafir, Durado, Rabihe and Ingath),were grown in a field experiment at Al-Khalis station research . spring and autumn seasons of 2008 The aim of the study was to investigate the relationships between grain filling duration (GFD) and sorghum grain yield. This experiment was planted as a randomized complete block design(R.C.B.D.) with three replications. The results showed that significant positive correlations of (GFD) were found among (GFD) with days number to 50% anthesis ,number of days to physiological maturity and grain yield . Significant positive correlation was also noticed among days to 50% anthesis, days number to physiological maturity and grain yield. The linear regression coefficient between grain yield and days to 50% anthesis indicates an increase (22.392, 9.483 kg.ha-1) in grain yield for each additional day required for (GFD). | ||
