Resumo: | This study was carried out at Escola de Agronomia of’ Universidade Federal de Goiás in the 1992/93 agricultural year with the purpose of evaluating popcorn cultivars for Goiânia-GO region. The essay had 19 treatments on a randomized complete design block with 4 repetitions. The following cultivars were used as part of the Popcorn National Essay coordinated by CNPMS/EMBRAPA: H-16, CMS 42 C-I, CMS 42 C-II, CMS 43 C-I, CMS 43 C-II, UNB-2, PIRAPOCA EPAMIG, ZÉLIA-0l, SAM (STA. CECÍLIA), ROGO POP 1, ROGO POP 2, ROGO POP 3, MF 1001, MF 1002, GO 100-P, COLORADO POP 1, COLORADO POP 2, RS-20 and BR-440. It was evaluated plant height and first ear insertion height, sick plants percentage, ear index, final stand, grain/ha yield and popping expansion capacity index (E.C.). The H-16 cultivar presented the highest grain yield (2,928 kg/ha) but low E.C. (11.9). The triple hybrid ZÉLIA-0l had good performance with 22.1 E.C. and l,770 kg/ha. This yield was 12% higher than the pattern cultivar SAM (STA. CECÍLIA) with 1,492 kg/ha and 15.5 P.E. It was found high positive correlation among yield and female flowering date, ear index and plant and ears height. Popping expansion capacity did not present any correlation among P.E. and another studied characters. KEY-WORDS: Zea mays; pop-corn. |

O milho pipoca é muito consumido pela população brasileira, havendo da parte dos pesquisadores e produtores uma procura constante de cultivares mais produtivas e adequadas ao cultivo em escala comercial. Com objetivo de avaliar cultivares de milho de pipoca, conduziu-se um experimento no ano agrícola de 1992/93 na Escola de Agronomia da Universidade Federal de Goiás. O ensaio constituiu-se de 19 tratamentos com 04 repetições no delineamento de blocos ao acaso. Os tratamentos constituíram-se de 19 cultivares, constantes do Ensaio Nacional de Milho Pipoca coordenado pelo CNPMS/EMBRAPA, a seguir relacionadas: H-16, CMS 42 C-I, CMS 42 C-II, CMS 43 C-I, CMS 43 C-II, UNB-2, PIRAPOCA EPAMIG, ZÉLIA-0l, SAM (STA. CECÍLIA), ROGO POP 1, ROGO POP 2, ROGO POP 3, MF 1001, MF 1002, GO 100-P, COLORADO POP 1, COLORADO POP 2, RS-20 e BR-440. Avaliaram-se altura de plantas, altura de inserção da 1ª espiga, % de plantas doentes, índice de espigas, stand final, produção de grãos/ha e o índice de capacidade de expansão (C.E.). A cultivar que apresentou a maior produção de grãos/ha foi a H-16 (2.928 kg/ha), mas teve uma C.E. muito baixa (11,9). Destacou-se o híbrido triplo Zélia - 0l, com uma capacidade de expansão 22,1 e uma produção de 1.770 kg/ha, 12% mais produtiva do que a testemunha S.A.M. (1.492 kg/ha e C.E.= 15,5), a mais plantada no Brasil. Observou-se uma forte correlação positiva entre a produção com a época de florescimento feminino, índice de espigas, altura de plantas e de espigas. Não foi observada nenhuma correlação entre a capacidade de expansão e os outros caracteres estudados.
