Inheritance of Fruit Weight, Size and Organic Acid Content in a Distant Hybrid Population of Longan ‘Huanongzao’ and Lychee ‘Ziniangxi’

The type and content of organic acids in fruits are important factors that determine the traits, such as nutrition flavor fruits. Fruit weight size also very economic characters fruit breeding research. To investigate inheritance patterns longan, acid contents, weight, were measured distant hybridization progenies longan ‘Huanongzao’ lychee ‘Ziniangxi’. results revealed malic accumulation exhibited mid-parent heterosis, citric showed a tendency towards depression, oxalic acid, ketoglutaric fumaric gallic total contents transgressive inheritance. length diameter tended smaller degraded. coefficient variation (CV) for ranged from 35.77–90.20%, heritability (H2) was 72.35–97.44%. High CV (55.44%) coupled with medium H2 (28.72%) observed however, low (12.29% 12.50%) high (68.95% 69.25%) shown diameter. In this study, genetic F1 population analyzed first time, providing an informative theoretical basis selection cultivars.
