“…The range values of seed sizes in this study (length, width and ratio) are similar to those reported by Azeez and Morakinyo (2011). Our result for the six physical dimensions is more closer to those observed by Arafa (2007) in Egypt;Akintunde (2004 and2007) and Adebowale et al (2010) in Nigeria.…”

“…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. Kehinde et al (2017) also reported similar result in Hibiscus cannabinus.…”

“…Since our previous work (Quenum, 2002), very few studies have been reported on the physical properties of the seeds of sesame. Some informations are available on the use of seed morphometric data for sesame germplasm analysis ( Azeez and Morakinyo, 2011;Adebowale et al , 2011, Prasad et al, 2013. This work has the aim to estimate biometric characteristics of seeds of a sesame mini-core collection through digital image analysis and use statistical means to identify and distinguish one accession to another; and subsequently to analyze variability to understand the diversity of seed morphometric traits.…”

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.

“…Comparatively, previous studies have shown that multivariate analyses of protein variation (Azeez et al, 2013), seed physical dimension (Azeez and Morakinyo, 2011a), and seed oil and fatty acid profile (Azeez and Morakinyo, 2011b) recorded 45.70 %, 88.96 % and 80.95 % for the first two principal components respectively. In some other investigations on sesame, multivariate analysis of morpho-physiological (Tabatabaei et al, 2011) and morpho-agronomic (Ercan et al, 2002) traits yielded 38.51 % and 45.30 % respectively for the first two principal components, while that of phytochemical characters recorded 91.86 %.…”

Sesame collections were evaluated for quantitative floral characters and data obtained were subjected to various statistical analyses. Result showed narrow diversity in most of the quantitative floral characters with moderate variability in length of flower (2.03-3.27 cm), length of style (1.10-1.40 cm), length of capsule (2.33-2.98 cm) and number of seeds per capsule (38.67 -57.67). Correlation study revealed significantly (p < 0.01) positive correlations for length of ovary versus length of flower (r= 0.70) and length of capsule versus length of style (r= 0.77). The first two principal components accounted for 61.59 % of which the first component had 34.13 % and the second was 27.46 %. Dendrogram divided the seventeen accessions/landraces into two major groups (A and B). Group A had only one cluster with five members whilegroup B had three clusters (Cluster II, III and IV) with seven, three and two members respectively. Each accession within a cluster could be employed as baseline parent in crossbreeding for improvement of yield in Nigerian sesame. Key words:

“…Therefore, the least expensive management measures, such as use of host resistance and cultural control, will find favor with farmers and others concerned with more oilseed production. In recent years, the gains in productivity of oilseed crops have been achieved primarily through exploitation of genetic vari ability (Anjani 2012, Azeez and Morakinyo 2011, Zhang and Johnson 1999. Conventional breeding coupled with modern tools such as biotechnology should now be the primary focus in crop improve ment programs.…”

He has more than 22 years of research experience in oilseed crop disease management and has significantly contributed in the areas of understanding the host-pathogen interactions, epi demiology, and integrated disease management in sunflower, safflower, sesame, peanut, and rape seed-mustard crops. He has published more than 70 peer-reviewed research papers and 4 books. Dr. Chattopadhyay has to his credit several academic awards and one patent. His significant research achievements include the development of Fusarium wilt-resistant genotypes in safflower, the iden tification of genotypes of Brassica juncea resistant to a mixture of isolates of Albugo candida, the development of a biocontrol agent formulation to reduce the use of fungicides in the management of major diseases of oilseeds (Brassica), and seed treatment (and foliar application) of aqueous bulb extract of Allium sativum for the management of major foliar diseases (Alternaria blight, white rust, powdery mildew, and Sclerotinia stem rot) of mustard.
