Final kernel weight and kernel-filling rate were determined by fitting the broken linear model (Fig. 1). Kernel number was determined at final harvest at maturity. Maximum kernel water content and volume were determined from the average of the five highest values measured for each panicle section of a genotype.

For each experiment, means in columns that are followed by the same letter do not differ significantly (P <0.05).
