Genetic Associations Analysis in Tomato (Solanum lycopersicum L.) Involving Improved Germplasm Lines for Agronomic and Yield Contributing Traits

Genetic association analysis in advance tomato (Solanum lycopersicum L.) lines for horticultural and yield contributing traits

“…The correlation coefficient findings from the current study on tomato genotypes showed that total fruit yield showed high significant and positive phenotypic correlation with number of fruits per plant (0.909), lycopene content (0.789), percent seedling survival in the field (0.718), average fruit weight (0.688), pericarp thickness (0.490) and pollen viability (0.393). Similar findings for number of fruits per plant and average fruit weight were reported by Sunilkumar et al [5], Sushma et al [6], Maurya et al [7], Sharma et al [8], and Nevani and Sridevi [9]. Total fruit yield was also positively and significantly correlated with number of locules per fruit (0.276).…”

“…Nevani and Sridevi [9] also recorded positive association with pericarp thickness. In contrast, the negative association was found with number of fruits per plant by Sunilkumar et al [5] and Sharma et al [8]. Whereas, negative and highly significant correlation was found with dry matter content (−0.405) and total soluble solids (−0.357).…”

“…The characters such as number of fruits per plant (0.550), average fruit weight (0.531), percent seedling survival in the field (0.203) and pollen viability (0.121) had low to high positive effects for total fruit yield, while traits namely leaf curl disease incidence (0.031), dry matter content (0.024), percent seedling survival in the nursery (0.032), number of locules per fruit (0.031), number of days to first anthesis (0.012) and polar equatorial ratio (0.006) had lesser positive effects. Direct and high influence of number of fruits per plant and average fruit weight on total fruit yield was observed by Sunilkumar [5], Sushma et al [6], Maurya et al [7], Kumar et al [11], Sharma et al [8], Nevani and Sridevi [9]. The highest negative and direct effect on total fruit yield was presented by harvesting span (−0.104) followed by titratable acidity (−0.103), total soluble solids (−0.089), plant height (−0.084), pericarp thickness (−0.055), lycopene content (−0.053) and days from transplanting to first harvest (−0.006).…”

Tomato Leaf Curl Virus of Tomato: Scenarios and Confronts

“…These methods are highly efficient and advisable because LAMP and PCR identified the presence of the disease in the seedling at the very early stages, which is quiet beneficial. Also, the presence of the virus in soil and seeds is also checked simultaneously to check any further spread of the disease [55]. Altogether the biotechnology of the tomato leaf curl virus is understood by identifying the gene that is very important and responsible for replicationi.e., C1RAP gene.…”

A Brief Perspective on the Use of Bio-inoculants in Horticulture

“…There may be no easily available simple components or other bio-inoculants for bacteria conducting the most fundamental function on the site. A metagenomic analysis aiming at identifying and functionally characterising these essential microorganisms, according to the researchers, may give insight into their function as well as their connections with other bacteria in the microenvironment [51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70].…”
