dc.description.abstractA great deal of research has been carried out to evaluate dry matter accumulation and solar radiation utilization in normal maize genotypes whereas limited information is available on special genotypes such as high oil and high protein maize. In this paper, we made a comparative analysis on biomass production, solar radiation utilization and growth at five different stages before and after flowering in normal (B73 and Mo17) and specialty maize (IHO and IHP) lines. Specialty maize genotypes were from 70th cycle of Illinois Long Term Selection. We used 12 directly-measured traits, 10 energy calculations and 6 time interval computations obtained from measurements in five developmental stages. A nested design was used to compare temporal changes in the observed traits. We found significant differences between specialty and normal maize genotypes for most variables throughout the developmental stages. Normal genotypes had higher plant height than special ones. IHP strain had higher expanded leaf area than others, especially around the flowering. IHO produced higher dry matter per leaf area faster in the early stages and stayed green for longer, resulting in high values for total dry matter production and calculated energy equivalent. Radiation use efficiency (RUE) was higher in specialty maize compared to normal maize genotypes. The highest RUE was observed in IHP (1.36 g Mj plant(-1)) around flowering stage. Overall, specialty and normal genotypes showed significant differences for some agromorphological and physiological traits as well as energy utilization and conversion into dry biomass.
