ZP maize hybrids in the production trials in 2005

Abstract

An appropriate choice of the ZP hybrids is a result of studies on yielding carried out under different agroecological conditions. Results on yields of ZP hybrids (FAO 300- 700) obtained in production trials in 36 locations carried out in 2005 are presented. The highest yield were detected in the following hybrids ZP 544 and ZP 758, ZP 684 and ZP 578. Furthermore, hybrids ZP 544 and ZP 684 over yielded all hybrids under agroecological conditions of Bačka. In Banat new hybrids ZP 544 and ZP 758 were highly ranked, while the highest yield in Srem were detected in the hybrids ZP 544 and ZP 684, and in the Central Serbia were hybrids ZP 544 and ZP 578. Stated results point out to high yielding and adaptability of hybrids of a new generation (ZP 544, ZP 578, ZP 684, ZP 758). At the same time, high yields of already widely grown old hybrids (ZP 677 and ZP 704) were confirmed.

Pravilnom izboru ZP hibrida prethode ispitivanja rodnosti u različitim agroekološkim uslovima. Na osnovu proizvodnih ogleda na 36 lokaliteta izvedenih u 2005. godini prikazani su rezultati prinosa ZP hibrida (FAO 300-700). Po svojoj rodnosti posebno su se istakli novi hibridi ZP 544 i ZP 758, ZP 684 i ZP 578. Posmatrano u različitim agroekološkim uslovima u regionu Bačke najrodniji su bili ZP 544 i ZP 684. U regionu Banata najprinosniji su novi hibridi ZP 544 i ZP 758, u Sremu ZP 544 ZP 684, a u Centralnoj Srbiji ZP 544 i ZP 578. Navedeni rezultati ukazuju na visoku rodnost, stabilnost i adaptibilnost hibrida nove generacije (ZP 544, ZP 578, ZP 684 i ZP 758), kao i na proverenu i u praksi potvrđenu rodnost ranije stvorenih ZP hibrida (ZP 677 i ZP 704).
