Comprehensive evaluation of fruit quality traits in intergeneric hybrids of longan and litchi for individual selection
Aiming to breed a new cultivar with late maturation and large fruit size, three F1 intergeneric hybrids of longan and litchi populations, viz. 'Shixia' × 'Ziniangxi', Z'aoshu' × 'Ziniangxi' and 'Zhongqiu' × 'Ziniangxi' were evaluated under this experiment. Using the progenies as materials, 30 fruit quality traits including harvesting date, fruit weight, flesh thickness, seed weight, edible:non-edible ratio, soluble solids content, flavor of fruit, etc. were assessed and evaluated. The results showed that there was a significant difference in fruit quality traits among different hybrid progenies. The individual selections were evaluated by the quality weighed average, which was calculated as the scores of three different traits including fruit weight, the edible/non-edible ratio and the soluble solids content. Four hybrids ('Shizi-2', 'Shizi-9', 'Shizi-19' and 'Zaozi-1') were identified as superior individuals with a quality weighed average of more than 83, showing late maturation, large fruit size with high edible/non-edible ratio. Hence, these individuals will have great value in production application and breeding.
