“…The result indicated that there is good scope for insect resistant improvement in sorghum through hybrid breeding. Similar results were reported by Agrawal and Abraham, 1984 [1] ; Tahir, 2005 [10] ; Aruna et al, 2013 [2] and reported that hybrid breeding can contribute to greater extent in breeding of resistant genotypes of forage sorghum.…”

Sorghum being a C4 crop has diverse uses as food, feed, fodder and fuel. But among kharif forages sorghum has great potential to provide quality forage and fodder for animal use. It is best suited in semiarid regions due to its drought tolerance nature as compared to fodder maize. By keeping these points in consideration, we have planned an experiment to evaluate eleven CMS based forage sorghum hybrids for green and dry biomass potential along with their fodder quality along with two checks. The most productive hybrids among them were

“…Genotype × environment interaction is commonly observed as the differential ranking of genotypes across environments (Mohammadi & Amri 2013) and GEI for forage yield and quality in forage sorghum has been reported earlier (Aruna et al . 2012). The GGE biplot is a tool to visualize the patterns of GEI in a graphical manner (Yan 2001; Yan & Tinker 2006), and also helps in identifying relationships among traits and detecting the best genotypes for different traits.…”

Forage sorghum is an important component of the fodder supply chain in the arid and semi-arid regions of the world because of its high productivity, ability to utilize water efficiently and adaptability to a wide range of climatic conditions. Identification of high-yielding stable genotypes (G) across environments (E) is challenging because of the complex G × E interactions (GEI). In the present study, the performance of 16 forage sorghum genotypes over seven locations across the rainy seasons of 2010 and 2011 was investigated using GGE biplot analysis. Analysis of variance revealed the existence of significant GEI for fodder yield and all eight associated phenotypic traits. Location accounted for a higher proportion of the variation (0·72-0·91), while genotype contributed only 0·06-0·21 of total variation in different traits. Genotype-by-location interactions contributed 0·02-0·13 of total variation. Promising genotypes for fodder yield and each of the associated traits could be identified effectively using a graphical biplot approach. The majority of test locations were highly correlated. A 'Which-won-where' study partitioned the test locations into two mega-environments (MEs): ME1 was represented by five locations with COFS 29 as the best genotype, while ME2 had two locations with S 541 as the best genotype. The existence of two MEs suggested a need for location-specific breeding. Genotype-by-trait biplots indicated that improvement for forage yield could be achieved through indirect selection for plant height, leaf number and early vigour.

“…In this regard, the cytoplasm can have a significant impact on the manifestation of these traits. There is a lot of data in the literature confirming the effect of the cytoplasm on agronomically valuable traits in wheat (Atienza et al, 2007), rice (Tao et al, 2011), cotton (Tuteja, Banga, 2011), pearl millet (Amiribehzadi et al, 2012), winter rye (Urban, Gordey, 2013), sorghum (Aruna et al, 2013), sunflower (Jan et al, 2014), maize (Kabanova et al, 2015), and mustard (Chakrabarty et al, 2015). Assuming that the manifestation of heterosis in F 1 hybrids is determined, in considerable extent, by the combining ability (CA) of maternal lines, investigation of the effect of cytoplasm on CA is of significant interest.…”

Investigation of the effect of the cytoplasm on the combining ability (CA) of lines with cytoplasmic male sterility (CMS) is of considerable interest in terms of understanding the genetic functions of the cytoplasm and for practical purposes to create hybrids with improved economically valuable traits. In order to investigate the effect of different types of sterile cytoplasm (A3, A4, 9E) on CA in sorghum, we studied the manifestation of a number of biological and agronomic traits in 54 F1 hybrid combinations obtained using iso-nuclear CMS lines with the nuclear genome of the line Zheltozernoye 10, differing only in the types of sterile cytoplasm (A3, A4 and 9E). Eighteen varieties and lines of grain sorghum developed at the Russian Research and Project-technological Institute of Sorghum and Maize were used as paternal parents. The CA was determined by the topcross method. F1 hybrids and their parents were grown in 2015–2017 in conditions of insufficient (2015–2016: HTC (hydro-thermal coefficient) = 0.32–0.66), or good water availability conditions (2017: HTC = 1.00). On average, for three years of testing, a positive effect of the 9E cytoplasm on the general combining ability (GCA) (0.63) and negative effects of the A3 and A4 cytoplasms (–0.32 and –0.31) for the inflorescence length were noted. In dry seasons, significant positive effects of the 9E cytoplasm on GCA for the length of the largest leaf, and positive effects of the A3 cytoplasm on GCA for the plant height, and negative effects of the A4 cytoplasm on GCA for these traits were observed. No differences were observed during the wet season. The type of CMS did not affect the GCA for the width of the largest leaf and grain yield. The dispersion of specific combining ability (SCA) in the dry seasons was significant for the following traits: leaf length, plant height, panicle length and width, and grain yield, the 9E cytoplasm had the highest SCA dispersion, whereas the A4 cytoplasm had the smallest one. The data obtained indicate that different types of sterile cytoplasm of sorghum make a different contribution to CA under conditions of drought stress.
