Abstract

Maize hybrid KSC 703 (K47/3 x MO17) produced grain yield 12.034 t/ha over seven locations in 2010, compared to KSC 704 with 12.034 t/ha, as check. During two years evealuation ( 2011-2012) over 12 locations, this hybrid revealed grain yield 11.291 t/ha, comparing to KSC 704 with 9.506 t/ha, showing 1.785 t/ha (18.8%) yield increase. On farm experimants carried out in Islam Abad, Ravansar, Mahtabi, in 2013, revealed 14.400 t/ha with 20.5% moisture, compared to KSC 704 by 11 t/ha with 23.1% moisture contenet in Islam Abad, Kermanshah province (3.667 t/ha yield increase and 2.6% less moisture content). In Ravansar (Kermanshah province), this hybrid showe average grain yied 16.233 t/ha with 20.5% moisture content, comparing to KSC 704, with 11.500 t/ha, with 23% moisture contenet, meaning 4.733 t/ha yield increase and 2.5% lower moisture content . In Mahtabi (Jiroft region), this hybrid yielded 2.815 t/ha more grain than KSC 704 (23%), and 3.815% less grain moisture at harvesting time.
