Environmental effects on correlation and path coefficient estimates for three groups of agronomic traits affecting grain yield of sorghum [electronic resource].

Includes references.

To examine tile influence of environment on tile interrelationships between agronomic traits of grain sorghum affecting grain yield, 30 restorer and 20 maintainer lines were compared under two water regimes (normal irrigation Will post-flowering stress) in two locations during the growing seasons of 2003 and 2004. Tile combined analysis for agronomic traits and yield components slowed significant differences among the genotypes, locations, years and water regimes. Correlation between studied traits generally displayed the same trend in the six environments. However, significant differences between water regimes for estimates that associations between number of green leaves and kernels/head, panicle length, plant height and grain yield/plant. Similarly, cstimates of correlation coefficients were significantly different between locations for days to 50% heading and plant height, panicle width, grain yield/plant and kernel number/head and for tile correlation between plant height with panicle length, and leaf area and number of green leaves. No significant differences were observed between correlation estimates due to year effects…
