CARACTERIZAÇÃO, ADAPTABILIDADE E ESTABILIDADE TEMPORAL DE GENÓTIPOS AVANÇADOS DE MORANGUEIRO DE FOTOPERÍODO NEUTRO

Abstract

The strawberry is among the most cultivated small fruits in the world, being present in all continents, except Antarctica. Known for its sharp flavor and pleasant aroma, the strawberry is rich in nutraceutical compounds of great interest to the health of those who consume it. The species, being octaploid, presents a complex inheritance of characters, in addition to great interaction with the environment, which results in different phenotypic expressions. Thus, in the development of cultivars, this interaction must be evaluated based on parameters related to heritability, stability and adaptability of genotypes to different soil and climate variations. Thus, the objective was to estimate the stability and temporal adaptability of pre-selected triple neutral-day strawberry hybrids, through the methodology of mixed linear models. Thirty-six experimental genotypes, three commercial cultivars (Albion, Monterey and Dover) and four single hybrids (RVFS07, RVFS06, RVDA11 and RVCA16) were evaluated in a protected environment between August and February under tropical conditions in the southern hemisphere. The genotypes RVFS07M-34, RVFS07M-24, RVDA11M-04, RVFS07M-36, RVFS07M-33, stood out with higher values of total fruit mass, in addition to greater adaptability and stability throughout the year.
