“…Whereas, plant height at 120 DAT (-1.153) had the highest negative direct effect on fruit yield per plant followed by number of flowers per cluster (-0.383), percent fruit set (-0.264), days to 50% flowering (-0.083), days to first picking (-0.033) and fruiting span (-0.0018). These results were conformity with Verma and Sarnaik (2000) [29] , Mohanty (2002) [17] , Mehta and Asati (2008) [15] and Kumar et al (2020) [10] .…”

Forty-three genotypes were studied for correlation and path co-efficient analysis in tomato (Solanum lycopersicum L.) at Horticultural Research centre, Department of Horticulture, Jawaharlal Nehru Krishi Vishwavidyalaya, Jabalpur (M.P.) during Rabi 2019-2020. The experiment was laid out in a Randomized Block Design (RBD) with three replications. Fruit yield had a positive significance correlation was associated with traits like average fruit weight, fruit length, number of fruits per plant, plant height at 120 DAT, days to 50% flowering and number of days to first picking. Strong association of these traits revealed that the selection based on these traits would ultimately improve the fruit yield. Hence, due weightage should be given to these characters while selecting the germplasm in crop improvement. In path coefficient analysis fruit yield per plant showed that number of fruits per plant, average fruit weight, number of fruits per cluster, number of primary branches per plant, fruit length, days to first flowering and fruit width observed positive direct effect at both genotypic and phenotypic level. These characters contribute maximum to high fruit yield compared to other characters, thus selection for these characters help in selection of superior tomato genotypes.

“…Number of locules showed a negative correlation with number of days to first flowering (-0.04), number of days to first fruit harvest (-0.01) and number of fruits per plant (-0.02), whereas it showed a positive correlation with remaining characters i.e., plant height (0.05), number of primary branches (0.12), plant spread (0.14), fruit weight (0.17) and fruit yield (0.19). The above results are in line with the finding of Madhurina and Paul [13], Maurya et al [14], Ara et al [15], Kumar et al [16] and Singh [17]. The correlation plot of all the characters is depicted in Fig.…”

Tomato is one of the most important vegetable crop grown by small farmers and commercial growers for both local uses as well as processing industries. So, it is important to increase its productivity along with desirable attributes through its genetic characters. Therefore, present experiment was conducted at the College of Agriculture, Vellayani, to evaluate the F2 segregating population of a tomato cross involving Anagha x IIHR 2896 for correlation and path analysis. Correlation analysis revealed that plant height, number of primary branches, plant spread, number of days to first flowering, number of days to first fruit harvest, number of fruits per plant, fruit weight, fruit volume, and number of locules were highly significant and positively correlated with fruit yield per plant. Path analysis revealed that the number of fruits per plant, fruit weight and fruit volume had a high positive direct effect on fruit yield per plant, followed by plant height and plant spread. However, the number of primary branches, the number of days to first flowering, the number of days to first fruit harvest and number of locules had a negative direct effect on fruit yield per plant. Hence, the characters showing positive correlation and direct effect should be given more emphasis in the selection programme for the development of superior varieties.

“…The estimated broad-sense heritability values for yield component characters included height criteria such as pericarp thickness, fruit length, fruit diameter, fruit weight, number of locular cavities, and number of fruits. Several researchers reported similar results for pericarp thickness [1], fruit length [14], fruit diameter [1,10], fruit weight and number of locular cavities [9], and number of fruits [15]. The estimated heritability values for fruit yield characters per plant revealed high criteria.…”

Development of tomato in the lowlands is a solution to increase tomato production in Indonesia. Genotype selection using an appropriate criteria can help to obtain the tomato genotypes with have high production in the lowlands. This study was aimed to determine the appropriate selection criteria for tomatoes with high production in the lowlands. This study was organized in a randomized block design with three replications. The genotype used in this study was a collection of pure line from IPB's breeding laboratory. The results showed that several characters had a significant correlation with fruit weight per plant. Determination of selection criteria based on characters that have high heritability values with a significant correlation to fruit weight per plant. The characters of fruit length, weight per fruit and plant crown width have very significant correlation values with fruit weight per plant, so these three characters can be used as selection criteria.
