Adaptability and stability analysis via GGE biplot in single, double, and interpopulation maize hybrids.

The interaction of genotype by environment challenges material selection for specific regions. The GGE biplot methodology proves to be effective in detecting and addressing this complexity. This study evaluated the performance of eight maize hybrids in three locations in the North/Northwest of Rio de Janeiro during the winter 2021-2021 and summer 2021-2022 crop seasons.

Exploring genetic diversity in inbred papaya lines for fruit quality in advanced stage of improvement.

Despite the relevance of the global scenario regarding the papaya (Carica papaya L.) trade, there is still a limited number of papaya cultivars with different fruit patterns. Therefore, it is essential to explore the genetic variability at all levels of the germplasm used in the development of new papaya cultivars to meet its marketing goal.

Intra-genotypic variability in elite parent lines of papaya.

This study aimed to characterize papaya lines via microsatellite markers, and select genotypes based on the fixation index in order to promote the genetic purification of important commercial hybrids parent lines. Overall, 400 genotypes from three parental lines (JS-12, SS-72/12, and Sekati) were genotyped. Expected (HE), observed (HO) heterozygosity, and fixation index (F), were estimated.

Sensory acceptance and qualitative analysis of fruits in papaya hybrids.

Over the last three years, Brazil has been ranked among the three largest producers of papaya. This study aimed to evaluate the acceptance and commercial standard of papaya fruits according to their sensory traits and provide information about the organoleptic and qualitative aspects of the fruit. Ten papaya genotypes grown in Linhares-ES were investigated, arranged in a randomized block design with four replications.
