摘要

摘要采用REM/BLUP混合模型估计了芒果杂交种果实品质的遗传参数。在两个作物季节对27个杂交种(Tommy Atkins与Haden、Palmer、Van Dyke、Kent和Coquinho杂交)进行了评价。理化性状分析包括重量、纵向长度、横向直径、纤维存在、果肉硬度、皮和果肉颜色、纤维存在可滴定酸度和可溶性固形物(SS)。重复性从0.53 (SS)到0.89(直径)不等。选择精度(Acm)基于从0.73 (SS)到0.94(重量、长度和直径)不等的平均收成。根据选育增益和新平均选择了最有前途的杂种。

Estimation of Genetic Parameters and Prediction of Breeding Values for Fruit-Quality Traits in Hybrid Mangoes

ABSTRACT Genetic parameters to fruit quality of mango hybrids were estimated using a mixed model REM/BLUP. Twenty-seven hybrids (Tommy Atkins cross with Haden, Palmer, Van Dyke, Kent and Coquinho) were evaluated, in two crop seasons. Physical and chemical traits analyzed were weight, longitudinal length, transverse diameter, fiber presence, pulp firmness, skin and pulp color, fibers presence titratable acidity, and soluble solids (SS). Repeatability varying from 0.53 (SS) to 0.89 (diameter). Selective Accuracy (Acm ) based on average harvests varying from 0.73 (SS) to 0.94 (weight, length, and diameter). According to selection gain and the new averages the most promising hybrids were selected.

期刊介绍： The International Journal of Fruit Science disseminates results of current research that are immediately applicable to the grower, extension agent, and educator in a useful, legitimate, and scientific format. The focus of the journal is on new technologies and innovative approaches to the management and marketing of all types of fruits. It provides practical and fundamental information necessary for the superior growth and quality of fruit crops. This journal examines fruit growing from a wide range of aspects, including: -genetics and breeding -pruning and training -entomology, plant pathology, and weed science -physiology and cultural practices -marketing and economics -fruit production, harvesting, and postharvest
