摘要

番石榴在巴西具有重要的经济价值。通过获得近交系培育新品种是一种很有前途的选择。利用瓜哇石楠种子属性对其S2科进行鉴定。对番石榴种子生理品质的不同性状进行了研究,并对番石榴种子的几何、质地和颜色特征进行了数字表型分析。采用Ward-Modified Location Model (MLM)方法对各变量进行同步分析,并进行个体方差分析,估计群体遗传参数。种子的几何性状对不同基因型的区分影响较大,与萌发变量和干物质质量的表型相关性较高。与种子质量相关的变量具有较高的遗传力,表明选择健壮基因型是成功的。Ward-MLM方法是一种检测番石榴基因型间遗传多样性的有效方法。因此,在番石榴育种计划中,具有高萌发潜力的差异最大的基因型可以推荐用于未来杂交或自交受精以获得新品系。

Phenomics approaches: genetic diversity and variance components in a S2 guava family by seed traits
ABSTRACT Guava is of great economic importance in Brazil. The development of new cultivars by obtaining inbreeding lines has been a promising option. The objective of this work was to evaluate the S2 families of Psidium guajava using seed attributes. Different characters of physiological quality of guava seeds were studied, in addition to performing digital phenotyping of characteristics of geometry, texture and colors of the seeds. The variables were analyzed simultaneously using the Ward-Modified Location Model (MLM) method and carried out individual analyses of variance for estimating genetic parameters of the population. The formation of more than one group of divergent genotypes was observed, the geometry characteristics were more impacting for the discrimination of the genotypes, a high phenotypic correlation was observed with the germination variables and dry matter weight. High heritabilities were verified for the variables related to seed quality, indicating success in selecting vigorous genotypes. The Ward-MLM method is a useful tool to detect genetic diversity among genotypes of inbred guava. Thus, the most divergent genotypes with high germination potential can be recommended for future crosses or self-fertilized to obtain new lines in the guava breeding program.
