Correlation coefficients of morphological: Productive traits of species of Sorghum genus

Abstract

Objective of the research were phenotypic and genetic correlation coefficients of three species of Sorghum genus-forage sorghum S. bicolor Moench. (genotype NS-Džin), Sudan grass S. sudanense L. (genotype Zora) and interspecies hybrid S. bicolor x S. sudanense (genotype Siloking). Studies were carried out on samples of plant material from the first cut. The following morphological-productive traits were studied: plant height, number of leaves per plant, mass of leaves on the stem, average stem mass and yield of green biomass. In the analysis of genetic and phenotypic coefficients, differences depending on the impact on studied morphological-productive traits are observed. The highest value of the stem height was recorded in Sudan grass (2.281 m), as well as number of leaves per plants (7.917). The greatest mass of leaves per plant was established in forage sorghum (49.05 g), and the highest average stem mass was recorded in interspecies hybrid plants (80.798 g). Variation of morphological-productive indicators per species was significant and very significant. Coefficients of simple correlations indicate the presence of very strong to almost complete, statistically very significant positive correlations, so these effects were expected. Plant height and number of leaves were not directly but indirectly statistically significant to yield of green biomass and varied from insignificant and very weak to sporadically medium strong and statistically significant.

The effect of nitrogen fertilizer rates on green biomass and dry matter yield of Sorghum sp. at different growth stages

“…The highest dry matter yield was obtained for the interspecies hybrid Siloking, followed by the Sudan grass genotype Zora, whilst the lowest yield was obtained for the forage sorghum genotype Džin. With increasing N rates, the dry matter yield also increased, which was in line with the results of previous research by Janković et al, 2012;Sikora et. al., 2012;Ikanović et al, 2013;Rakić et al, 2013, and came as a result of higher yield and better quality of green biomass.…”

Correlation and path analysis study of different characters for grain yield and fodder purpose in sorghum [Sorghum bicolor (L.) Moench]

“…In the present study, grain yield per plant was found to be significantly and positively correlated with leaf width, leaf area, panicle width, dry fodder yield per plant and 1000-grain weight at the genotypic level. The positive and significant genotypic association has been reported by Seetharam and Ganesamurthy (2013) (2018), Jankovic et al (2012), Jain and Patel (2014). The grain yield per plant also registered positive, but non-significant correlation with days to flowering, days to maturity, leaf length and panicle length.…”

Genetic Variation, Correlation and Gene Action Study for Yield and Oil Quality Parameters in Sesame

“…The qualities of standard sesame for export must be color sorted, well dried, washed, cleaned and having good oil content that ranged from forty to sixty percent. The other qualities 1644 IJBPAS, August, 2018, 7 (8) necessary to meet the demand standards are disease free, pest as well as drought resistant for the country like Pakistan which is facing the water shortage problem due to wrong policies from the government side by delaying the construction of different dams.…”

“…The production of the crop depends upon its ability to accumulate its reserves and its adoption in varying and harsh environment [6][7]. For crop improvement, it is necessary thing to have the correlation knowledge of major yield parameters for effective response for selection [8]. For improvement purpose of major plant parameters, the correlation analysis is important to know [9][10].…”
