摘要

PCCMCA的统一检测包括在拉丁美洲20个不同环境中对30个coro杂交种进行评估。从1990年开始的结果证明了杂交玉米的一致性，在51个地方:HB-85、HB-83和XH-53连续三年保持第一，产量高达6000公斤/公顷(比对照高27%)。稳定性参数证实了该响应的拟合性。来自私营公司和国家项目的新杂交品种显示了植物育种方面的持续进步。

Respuestas diferenciales para rendimiento de híbridos maíz evaluados en ambientes contrastantes de latinoamérica PCCMCA 1990

The uniform assay of the PCCMCA involves the evaluation of 30 coro hybrids in 20 contrasting environments in Latin America. The results from 1990 prove the consistency of response of come coro hybrids which have remaines in the first places during three years through 51 localities: HB-85, HB-83 and XH-53, with yields up to 6000 kg/ha (27% over the control). The stability parameters confirm the fitness of this response. New hybrids from private companies and national programmes show a continuous progress in plant breeding.
