Characterization of Sorghum germplasm for various qualitative traits

Abstract

Present study was performed to characterize 750 germplasm lines with 4 checks namely CSV17, CSV20, CSV27 and CSV21F for various qualitative traits of Sorghum. These 754 genotypes were sown in augmented RBD with 30 replications during Kharif 2014 at Instructional Farm, Rajasthan College of Agriculture, Udaipur. Majority of the accessions showed poor early plant vigour (40.2 %), dark green leaf (88.6 %), non- tan leaf sheath pigmentation (60 %), drooping leaves (100 %), white midrib colour (51.6 %), senescence (60 %), loose panicle density (31.5 %), elliptical panicle shape (66.5 %), straw glume colour (48.2 %), 3/4 glume coverage (42.9 %), absence of awns (59.5 %), creamy straw seed (39.9 %), oval grain shape (48.8 %), medium seed size (43.7 %), non-lustrous seed (62.0 %), intermediate endosperm texture (50.3 %) and bicolor race (49.6 %). Very good early plant vigour, tan type leaf sheath pigmentation, drooping leaf orientation, straw glume colour, ½ glume covering, oval grain shape, intermediate endosperm texture appeared in all the 4 check. The results of this study indicated that considerable genetic diversity exists among the sorghum accessions.

Genetic diversity analysis of East African sorghum (Sorghum bicolor [L.] Moench) germplasm collections for agronomic and nutritional quality traits

“…White leaf midrib was present in 70.4% of the tested genotypes. This is contrary to Verma et al. (2017) , who reported a high level of genetic variation for leaf midrib color among sorghum collections in India.…”

Morphological Variability and Taxonomic Relationship of Sorghum bicolor (L.) Moench Accessions Based on Qualitative Characters

“…3). The presence or absence of awn is one of the important characters in the racial classification of sorghum [6], and this character is beneficial for certain sorghum cultivars since the presence of awn prevents the grains from being eaten by birds [24]. The character of glume coverage, or the degree of glume enclosing over the grains, showed high variability which can be classified into four categories namely 25%, 50%, 75%, and 100% coverage.…”

SSR Marker-based DNA fingerprinting and morphological characterization for varietal identification in popular sorghum varieties of Tamil Nadu

“…The fodder sorghum variety CSV 33 MF had a very long glume cover compared to all the other grain sorghum varieties in the present study. The grain sorghum exhibits lesser glume coverage and could be easily threshable, while fodder sorghum exhibits higher glume coverage indicating difficulty in threshing (Verma et al, 2017). Moreover, the cultivar TNS 660 had greyed red glume color and CSV 33 MF had greyed purple glume color.…”

“…Elite sorghum genotypes were first selected based on morphological characterization (Beta and Corke, 2001). However, from several studies, it is significant that morphological markers alone are insufficient due to low level of heritability, low level of abundance and is highly influenced by the environment (Seetharam and Ganesamurthy, 2013, Verma et al 2017, Bhusal et al 2017, Prajapati et al 2018.…”
