“…These results confirm the importance of certain Algerian local varieties compared to the hybrid for the markers mentioned. These results are in agreement with Kavithamani et al (2019) who found that the important morphological traits of PC1 are due to variations between accessions and confirm that the Algerian landraces presented some good characters at the future breeding programs.…”

The present study was performed to assess the native Algerian sorghum germplasm,20 accessions originating from the South of Algeria and one introduced commercial hybrid were evaluated for 12quantitative agro-morphological markers. Analysis of variance revealed significant differences (p ˂ 0.05) between accessions for all characters. Comparison of means by Duncan’s least significant test separate accessions into several homogeneous groups. It was found that sorghum landrace Ai19 showed the highest scores of final height (317 cm) and biomass dry yield (38 tons), Ai13 showed shortest vegetative cycles by 75 days to 50% flowering and the highest exploration of water to accumulate dry matter. The first two-principle component showed together more than 76% of the total variation. Clustering analysis showed that the 20 accessions were divided into four groups, mainly differentiated by forage production, days to 50% of flowering, final height, tillering capacity and leaf characteristics. The current study demonstrates that the characterization of the entire collection revealed a great phenotypic variability within the accessions and showed those that have markers of agronomic interest. Agro-morphological traits were very practical in detecting variation between local and commercial hybrid sorghum. Landraces Ai19, Ai13 and Fr1, through their valuable agro-morphological markers, could be used in sorghum genetic breeding programs.

“…Genetic diversity in sorghum is well studied, however, most reports remain focused on growth, yield, and nutritional quality of plants. 52 , 53 Three sorghum cultivars in this study showed quantitative metabolic differences, namely in linalool, DMNT, and ( Z )-3-hexenyl acetate ( Figures 3 , 4B), which contents were higher in Epuripur headspace ( Figure 3 ). Previously, ( Z )-3-hexen-1-ol acetate was dominant (65%) in volatile blend of 4-week-old sorghum, 54 and this compound was important for attractiveness to shoot fly ( Atherigona soccata ) in GC-EAG.…”

Acute stress responses include release of defensive volatiles from herbivore-attacked plants. Here we used two closely related monocot species, rice as a representative C3 plant, and sorghum as a representative C4 plant, and compared their basal and stress-induced headspace volatile organic compounds (VOCs). Although both plants emitted similar types of constitutive and induced VOCs, in agreement with the close phylogenetic relationship of the species, several mono- and sesquiterpenes have been significantly less abundant in headspace of sorghum relative to rice. Furthermore, in spite of generally lower VOC levels, some compounds, such as the green leaf volatile ( Z )-3-hexenyl acetate and homoterpene DMNT, remained relatively high in the sorghum headspace, suggesting that a separate mechanism for dispersal of these compounds may have evolved in this plant. Finally, a variable amount of several VOCs among three sorghum cultivars of different geographical origins suggested that release of VOCs could be used as a valuable resource for the increase of sorghum resistance against herbivores.

“…Principal component and hierarchical cluster studies with eight quantitative traits in 100 germplasm accessions of sorghum (Sorghum bicolor L. Monech) also revealed that 100 seed weight, plant height, leaf blade length and width were important traits depending upon their loading variables on a common principal axis and eight accessions were identified as superior genotypes for further utilization in breeding of high yielding sorghum varieties ( Kavithamani et al, 2019).…”

The present investigation aimed to assess the nature and magnitude of genetic divergence available in the Hybridization Block (E1) and National Hybridization Garden (E2) of ICAR-Sugarcane Breeding Institute, Coimbatore and to select the suitable diverse genotypes as parents for further utilization. Principal component and hierarchical cluster analyses were carried out in sixty eight genotypes with nine traits. In E1, the first three principal components explained about 73.45 per cent of the total variability and remaining six components accounted 26.55 per cent of variability. The PC 1 explained a maximum variability of 44.85 per cent followed by PC 2 and PC3. In E2, the first three principal components explained about 76.71 per cent of the total variability among the genotypes and the remaining six components described 23.29 per cent towards the total diversity. Nineteen clones viz., Co 0314,
