“…The positive correlation among these yield contributing traits suggested that these characters are important and are also good indicator for direct selection of high yielding genotypes. Similar results were reported by Elangovan et al [12]; Abubakar and Bubuche [16]; and Kannababu et al [27]. The width of third leaf from top and length of third leaf from top were highly associated as reported by Khaliq et al [28].…”

Sorghum [Sorghum bicolor (L.) Moench] is an important staple food crop in northern Benin. In order to assess its diversity in Benin, 142 accessions of landraces collected from Northern Benin were grown in Central Benin and characterised using 10 qualitative and 14 quantitative agromorphological traits. High variability among both qualitative and quantitative traits was observed. Grain yield (0.72–10.57 tons/ha), panicle weight (15–215.95 g), days to 50% flowering (57–200 days), and plant height (153.27–636.5 cm) were among traits that exhibited broader variability. Correlations between quantitative traits were determined. Grain yield for instance exhibited highly positive association with panicle weight (r = 0.901, P = 0.000) and 100 seed weight (r = 0.247, P = 0.000). UPGMA cluster analysis classified the 142 accessions into 89 morphotypes. Based on multivariate analysis, twenty promising sorghum genotypes were selected. Among them, AT41, AT14, and AT29 showed early maturity (57 to 66 days to 50% flowering), high grain yields (4.85 to 7.85 tons/ha), and shorter plant height (153.27 to 180.37 cm). The results obtained will help enhancing sorghum production and diversity and developing new varieties that will be better adapted to the current soil and climate conditions in Benin.

The experiment was conducted at College of Agriculture, Raichur, University of Agricultural Sciences, Raichur, Karnataka, India during October 2021–Februrary 2022 to characterize the 100-coloured sorghum genotypes along with four checks viz., M 35-1, AKJ 1, Paiyur 2 and GS-23 for eight qualitative characters and 10 quantitative characters in an augmented block design. The results revealed that, majority of the genotypes exhibited the pigmented stem (93%) and leaves almost green (61%) at harvest, horizontal flag leaf orientation (100%), loose erect primary branches of panicle (38%), black glumes (58%), red grain colour (36%), circular grain shape (75%) and freely threshable (93%) characters. For all the quantitative characters studied, a wide range of variation was observed. For stay green character, genotype IS 21868 showed completely green leaves. Similarly, for other characters also superior genotypes were identified in this study. Such genotypes can be used further in improvement of sorghum for its grain yield. For grain yield, 14 genotypes exhibited higher yields when compared to the best check GS-23, viz., IS 29032 (120.0 g), IS 6508 (119.18 g), IS 16006 (113.80 g), IS 28065 (102.88 g), IS 23890 (94.88 g), IS 28049 (94.28 g), IS 23865 (89.48 g), IS 29031 (87.98), IS 28202 (87.88), IS 31706 (86.48), IS 2582 (85.88 g), IS 28200 (83.58), IS 16398 (81.08 g) and IS 23955 (80.0 g). Eight genotypes were on par with GS-23. These genotypes can be further evaluated for its yield stability within and across locations.

“…Characterization of varieties is thus of significance for the purpose of establishment and verification of identity and assessment of varietal purity for seed production and certification (Singh et al, 2016). Previously study on diversity of inter specific sorghum has been reported using agro-morphological traits by various researchers (Ayana and Bekele, 2000;Joshi et al 2009;Reddy et al, 2009;Kannababu et al, 2013;Raghuvanshi et al, 2014). It is therefore, important to identify key diagnostic traits of different genotypes.…”

Abstract:The present investigation was conducted to characterize 20 genotypes of sorghum {Sorghum bicolor (L.) moench} on the basis of 33 morphological characters provided by Protection of Plant Variety & Farmer's Right Act (PPV&FRA) for Distinctiveness Uniformity and Stability (DUS) testing in sorghum. Experimental results revealed that maximum variation was found on the basis of glume colour among the genotypes i.e. G 46, HC 308, HJ 513 had green white, IS 3237, SSG 9, HC 171 had yellow white, SSG 59-3, COFS 29 had grayed purple, S 437-1, SGL-87, S 540-S, SSG (PSSG) had grayed yellow and remaining seven genotypes had grayed orange glume colour. The studied traits showed five genotypes had distinct state of expression. Genotype S-540 showed very high plant height upto the base of flag leaf, HC 136 had compact panicle density at maturity, COFS 29 had very long glume length, SSG 59-3 had distinct expression for days to panicle emergence (50 % of the plants with 50 % of anthesis) and COFS 29 and IS 18551 had short and very long leaf width of blade, respectively. The Principal Component Analysis (PCA) revealed principal Factor (PFI) and Principal Factor (PFII) with maximum variability (64.99 %). Classification of genotypes on the basis of DUS traits provided identification of key characteristics of various genotypes.
