“…This finding is in line with that of Daniel et al (2012) who suggested that those parameters are potentially good quantitative taxonomic descriptions of maize seed morphological classification. According to Azeez and Morakinyo (2011), with high positive and significant correlations the improvement in one of these attributes will positively affect others in sesame and will consequently lead to increase in seed size.…”

Seed morphometric parameters (seed area, length, diameter, circumference, roundness and aspect ratio) of 15 accessions were analysed. Measurements on seeds were taken with help of a Computer-Camera system. Variation among accessions and genetic relationships were estimated. Great variability was observed for all parameters studied. High positive or negative correlation (r=0.726-0.963) was showed by Pearson's correlation analysis for the seed metric data of the 15 accessions. The cluster analysis revealed that the 15 accessions could be grouped into three to five clusters according to the methods (Single or Complete Linkage) used. The principal components analysis showed that the first two components accounted for 99.3% of the variability. Morphometric characterization of seeds is rapid, reproducible, reliable and cost effective. This technique of digital imaging is strongly recommended for researchers from developing country like Benin, because of its efficiency.

“…Seed morphometric analysis involves measuring the dimensions (such as length, width, masses, angle, ratio and area) of seeds. It has been widely used to discriminate cultivars of many crops (Geetha et al, 2011;Grillo et al, 2011;Daniel et al, 2012). Geetha et al (2011), Grillo et al (2011), Sumathi and Balamurugan (2013 observed that this technique gives information that could be visually obtained repeatedly and faster.…”

The variability of grain yield, seed morphometric and vigour traits of early maturing hybrid maize

et al. 2021

Breeding for yield and quality requires the assessment of the seed metrics and vigour traits. This study, therefore, assessed the variability and inter-dependence of grain yield (GY), seed morphometric and vigour traits in hybrid maize. Seeds of 75 early maturing hybrid maize varieties were evaluated for morphometric traits and quality in four replicates. A field trial laid out in a randomised complete block design with three replicates was also conducted in Ibadan, Nigeria, to determine the grain yield of the hybrids. Data collected on the GY, seed dimension and quality were subjected to analysis of variance. The least significant difference was used to separate means. Relationships among the GY, seed morphometric and vigour traits were determined using correlation coefficients, while principal component (PC) analysis was performed for variability among the hybrids. Significant differences (P<0.001) were found in the GY, seed dimension and vigour traits. Four of the nine highest yielding hybrids had ECT higher than 30.0 ?sg-1 cm-1. The GY correlated with seed diameter (SDT) (0.40**), seed width (SWD) (0.36**), seed length (SLG) (0.35**), seed area (SAR) (0.30**) and seed vigour (SVI) (0.30**). The SAG correlated with SDT, SLG, seed thickness (STH) and SAR. All the seed vigour traits correlated with one another. The PC I explained GY, SDT, SWD, SLG, SAR and SVI, indicating their importance in GY improvement. Seed angle, length and diameter were versatile in maize varietal selection. Identified high yielding hybrids with seed morphometric and vigour qualities can be explored by seed companies as innovation in the seed production business.

Updated Methods for Seed Shape Analysis

2016

Morphological variation in seed characters includes differences in seed size and shape. Seed shape is an important trait in plant identification and classification. In addition it has agronomic importance because it reflects genetic, physiological, and ecological components and affects yield, quality, and market price. The use of digital technologies, together with development of quantification and modeling methods, allows a better description of seed shape. Image processing systems are used in the automatic determination of seed size and shape, becoming a basic tool in the study of diversity. Seed shape is determined by a variety of indexes (circularity, roundness, and J index). The comparison of the seed images to a geometrical figure (circle, cardioid, ellipse, ellipsoid, etc.) provides a precise quantification of shape. The methods of shape quantification based on these models are useful for an accurate description allowing to compare between genotypes or along developmental phases as well as to establish the level of variation in different sets of seeds.
