Genetics of fruit yield and it’s contributing characters in tomato (Solanum lycopersicom)

Abstract

Tomato is a premier vegetable crop of round the year and one of the prominent eco-industrial crops of India generating sizeable employment. The present study which consisted 10 genotypes was evaluated in randomized block design replicated thrice at Regional Agricultural Research Station-Ujjain during Rabi 2007 to 2008. The variation was maximum (424 to 825 qtl/ha) for fruit yield and minimum for fruit width (4.1 to 5.6 cm). The magnitude of genotypic and phenotypic coefficient of variation was higher for number of leaves (21.2 and 22.3), fruit length (cm) (19.6 and 19.7) and fruit yield (19.6 and 19.6). High values of heritability coupled with high genetic advance were observed for number of leaves at 60 days after transplanting (99.4 and 64.9), and fruit yield (99.9 and 24.7). A positive association of yield per hectare observed with number of leaves at 60 days after transplanting (0.78) followed by number of leaves at 30 days after transplanting (0.68), fruit length (0.66) and plant height (0.51).

Evaluation of Tomato (Solanum lycopersicum L.) Genotypes under Water Stress Based on Yield and Physiological Parameters

“…Similar findings were also reported by Golani et al, (2007), Dar and Sharma (2011), Kaushik et al, (2011), Rani and Anitha (2011) and Chernet et al, (2013.…”

“…Yield per plant showed the greatest range of variation as reported by Haydar et al, (2007), Mehta and Asati (2008), Ghosh et al, (2010), and Kaushik et al, (2011), followed by proline content, number of fruits per plant, stomatal frequency, fruit volume and number of leaves per plant (Table 2).…”

“…Narolia et al, (2012) and Kaushik et al, (2011) have also reported similar findings for plant height, average fruit weight and number of branches. High genotypic variance was observed for most of the characters indicating more contribution of genetic component for the total variation.…”

Genetic Analysis of F2 Population of Tomato for Quantitative Traits in the Cross Bushbeef X Nagina

“…Relatively higher difference was noted between GCV and PCV values in the traits: Flowers/cluster Fruits/cluster and Fruit weight and relatively low difference was noted for GCV and PCV value in the traits: Fruit diameter, Fruit length and fruits/plant. Khanom et al [4] also found smaller difference between GCV and PCV value for the trait fruits/length while Kaushik et al [14] found small difference between GCV and PCV for fruit diameter. Moderate difference was noted between GCV and PCV in the parameter yield/plant.…”
