“…These results were in supported by the findings Sharma and Thakur (2008), Prajapati et al, (2015). From the obtained results, it can be concluded that the genotypes studied in the present investigation exhibited a wide range of variation for various yield and yield contributing characters observed.…”

“…Hence, there is ample scope for selection of promising genotypes in breeding programme for yield related traits. Similar results with respect to analysis of variance also reported by Narolia et al, (2012), Agarwal et al, (2014), Reddy et al, (2014), Singh et al, (2014), Prajapati et al, (2015), Kumar and Singh (2016), Kumar et al, (2017a) and Kumar et al, (2017b).…”

The present investigation was carried out on thirty six genotypes of tomato for genetic variability assessment. The analysis of variance revealed that significant genetic differences were present among the tomato genotypes for all the traits studied. High GCV and PCV estimates were observed for number of fruits per plant, average fruit weight, fruit yield per hectare, fruit yield per plant, number of flowers per cluster and number of fruits per cluster. Number of fruits per plant recorded maximum heritability followed by average fruit weight, number of flowers per cluster, number of fruits per cluster, fruit length, days to first fruit ripening, fruit yield per plant, fruit yield per hectare, fruit width, 100 seed weight and days to first fruit set. High estimates of genetic advance as percentage of mean was observed for number of fruits per plant, average fruit weight, fruit yield per hectare, fruit yield per plant, number of flowers per cluster, number of fruits per cluster, fruit length, fruit width, 100 seed weight, fruit shape index and internodal length. Therefore, selection for these characters in segregating generations based on phenotypic performance would likely be more effective for further improvement in tomato.

“…Low genetic advance coupled with less heritability was noticed for P/E ratio indicating that, this trait was highly affected by environmental factors and genetic improvement were difficult through selection (JINDAL and KHAN, 2015). Similar results for these traits were also noticed by RAI et al (2016); PRAJAPATI et al (2015).…”

Agro-statistics, India is the second largest tomato producer only after China in the world. Tomato crop is grown round the year due to wider adaptability but production is adversely affected due to high incidence of tomato leaf curl virus and late blight diseases. These pathogens have enormous capacity to generate new forms and control of these pathogen are mainly achieved by chemical approaches which is not safe for environment as well as for human beings and also add an extra cost in tomato production. Therefore resistance breeding is best approach to manage these types of diseases along with improvement of yield and quality parameters. Five genes viz. Ty-1, Ty-2, Ty-3, Ph-2 and Ph-3 were tried to pyramid from different parent through hybridization to achieve resistance against tomato leaf curl virus and late blight diseases. In this study, 122 advance breeding lines of tomato were evaluated in 2016-17 and 2017-18, through phenotypic and genotypic screening to identify best lines having resistance to both the diseases with better horticultural traits. Punjab Chhuhara cultivar was used as common susceptible check to both the diseases while PVB-4 and LBR-10 were used as resistant 772
