بررسی عملکرد دانه و سازگاری هیبریدهای زودرس ذرت در مرحله نیمه نهایی

This study was conducted in Torogh agricultural research station (in Khorasan Razavi province). as two separate experiments. during one year (2008). The experimental design was randomized complete block design (RCBD) with four replications. In these experiments, 15 and 12 selected hybrids with two and three hybrids as control were evaluated, respectively. The results of first experiment showed that the whole of new hybrids had a desirable grain yield and were comparable with control hybrids (especially KSC370 and KSC 500). In second experiment, evaluated hybrids had a significant differdnce in grain yield (6. 678-11.150 ton/ha) and hybrid NO. 9 (KE 760010/1-1-1-1*K1263/1) (with 11. 150 t/h grain yield) had no significant differdnce in grain yield as compared with 11 number of hybrids. Key words: Maize- Grain yield - maturity- semi final experiments.
