Diallel mixed-model analysis of papaya fruit deformities

ABSTRACT

ABSTRACT Changes in the shape of fruits from hermaphrodite flowers due to floral anomalies are quite common. The aim of this study was to estimate the effects of the general and specific combining ability on the proportions of normal and deformed (carpelloid and pentandric) papaya fruits in hermaphrodite plants using mixed models. The JS12-N, Waimanalo and Golden parents showed the potential to decrease the number of deformed fruits. In contrast, the Maradol x JS12-N, Maradol x Waimanalo, Maradol x Golden, JS12-N x JS12-4, JS12-N x Sekati, JS12-N x Waimanalo, Waimanalo x JS12-N, Waimanalo x JS12-4, Waimanalo x Golden, Waimanalo x Sunrise Solo 72/12, Golden x Maradol, Golden x JS12-N, Golden x Sekati, Golden x Waimanalo and São Mateus x JS12-N hybrids have the potential to increase the number of marketable fruits while decreasing the number of carpelloid and pentandric fruits.

RESUMO

RESUMO Alterações na forma dos frutos originários de flores hermafroditas são bastante comuns. Estas alterações são provocadas por anomalias florais. Este trabalho teve como objetivo obter via modelos mistos estimativas de capacidade geral e específica de combinação para proporção de frutos de mamoeiro normais e com deformidades carpeloidia e pentandria, em plantas hermafroditas. Os genitores JS12-N, Waimanalo e Golden apresentam potencial para redução de frutos com deformidades. Os híbridos Maradol x JS12-N, Maradol x Waimanalo, Maradol x Golden, JS 12-N x JS12-4, JS 12-N x Sekati, JS 12-N x Waimanalo, Waimanalo x JS12-N, Waimanalo x JS12-4, Waimanalo x Golden, Waimanalo x Sunrise Solo 72/12, Golden x Maradol, Golden x JS12-N, Golden x Sekati, Golden x Waimanalo e São Mateus x JS12-N apresentaram potencial para aumento do número de frutos comerciais e redução de frutos carpelóides e pentândricos.
