辣木优良单株筛选比较

为筛选出优良的辣木果用种源,对30个辣木家系（每个家系15~30株）进行连续3年的跟踪观测及综合评价,以辣木种子产量为主要指标,同时兼顾株高、冠幅、地径以及果荚的相关性状指标（包括单果重、果荚长、果荚宽、单荚种子数等）,经初选、复选和决选,从30个家系中最终筛选出丰产、果型好、种子饱满的果用优良单株30株。研究结果可为后期辣木良种的选育提供基础材料,同时为干热区辣木树种的选育提供理论参考和技术方法。

Selection and Comparison of Excellent Individual of Moringa oleifera

To screen out elite fruit-based plants of Moringa oleifera, 30 Moringa families (15 to 30 strains per family) were used as test materials in this study through follow-up observation and comprehensive evaluation for three consecutive years. Yield was the main indicator, while consideration was also given to plant height, crown width, ground diameter and correlative indicators of fruit pods (including single fruit weight, fruit pod length, fruit pod width, number of single pod seeds, etc.). After primary selection, double selection and final selection, 30 excellent individual plants with good yield, well fruit type and full-seed were finally selected from 30 families. It could provide basic materials for selection and breeding of Moringa in the later period, and theoretical references and technical methods for Moringa breeding in hot and dry areas.
