Abstract:

An experiment was conducted to study the suitable maize hybrid in Hyderabad-Karnataka region. The experiment consisted of five hybrids viz., C.P. 818, C.P. 808, C.P.999, Arjun, and 900-M in four replications. It was revealed that all the five hybrids were raised in black soil during Kharif season of the year 2012-13. The physiological parameters and their relation with growth and yield attributes were analyzed in this experiment and results were computed. It was found that the higher individual cob weight was recorded in 900-M i.e., 338.4 g followed by C.P. 808 332.8 g and lowest was found in Arjun178.1g compared to other hybrid. Whereas, C.P. 818 has recorded higher shelling % (80) in addition to recording higher 100 seed weight i.e., 43.9 g followed by 900-M shelling % 79 and 100 seed weight 42.5 g compared to other hybrids. This may be due to having higher SPAD values (due to higher photosynthetic contribution) and stomatal conductance and shorter anthesis silking interval. Therefore, 900-M and C.P. 818 both the varieties performance were superior over the other hybrids in Hyderabad Karnataka region.
