Agronomic potential and indications for the genetic breeding of sweet corn local varieties carrying the sugary1 gene
ABSTRACT Sweet corn (Zea mays L.) local varieties are important gene sources for breeding programs, mainly in participatory research models. This study aimed to evaluate the agronomic performance of seven sweet corn local varieties (2255A, 2029A, 2276A, 2514A, 3000A, 741B and 319A) carrying the suga...

description | ABSTRACT Sweet corn (Zea mays L.) local varieties are important gene sources for breeding programs, mainly in participatory research models. This study aimed to evaluate the agronomic performance of seven sweet corn local varieties (2255A, 2029A, 2276A, 2514A, 3000A, 741B and 319A) carrying the sugary1 gene under homozygotic condition and two controls, at four environments [Anchieta (altitudes: 422 and 717 m), Guaraciaba (altitude: 624 m) and Florianópolis (altitude: 5 m)], in the Santa Catarina state, Brazil. The varieties 3000A and 319A showed a good performance in the different altitudes for ear and grain length and ear yield. At intermediate altitudes (422 and 624 m), the mean husked ear yield (milky grain) of these varieties were close to 12.5 t ha-1 (3000A) and 10.0 t ha-1 (319A). The varieties 2029A, 741B, 2514A, 2276A and 2255A stood out for ear length and diameter, number of ear rows and grain length. The best performance of the sweet corn local varieties was observed in their region of origin, mainly at altitudes ranging from 400 to 650 m. These varieties are adapted to the region and are promising alternatives to be used in breeding programs focused on finding a greater potential variability for selection purposes.
RESUMO Variedades locais de milho doce (Zea mays L.) representam importante fonte de genes para programas de melhoramento, especialmente em modelos de pesquisa participativa. Avaliou-se o desempenho agronômico de sete variedades locais de milho doce (2255A, 2029A, 2276A, 2514A, 3000A, 741B e 319A) portadoras do gene sugary1 na condição homozigótica e duas testemunhas, em quatro ambientes [Anchieta (altitudes: 422 e 717 m), Guaraciaba (altitude: 624 m) e Florianópolis (altitude: 5 m)], no estado de Santa Catarina. As variedades 3000A e 319A apresentaram bom desempenho nas diferentes altitudes para comprimento de espiga e de grão e rendimento de espiga. Em altitudes intermediárias (422 e 624 m), as médias de rendimento de espiga sem palha (grão leitoso) destas variedades ficaram próximas a 12,5 t ha-1 (3000A) e 10,0 t ha-1 (319A). As variedades 2029A, 741B, 2514A, 2276A e 2255A destacaram-se pelo comprimento e diâmetro da espiga, número de fileiras da espiga e comprimento do grão. O melhor desempenho das variedades locais de milho doce foi observado em sua região de origem, especialmente nas altitudes entre 400 e 650 m.
