“…Low heritability accompanied with low genetic advance demonstrated that these traits were profoundly affected by environment and selection would be inadequate and consequently these characters could be improved by hybridization only. These results were in similarity with the studies of Senugupta et al (2009) and Shokat et al (2013). https://doi.org/10.37992/2020.1104.197…”

The material of the present study consisted of twenty four genotypes of cherry tomato to study the genetic components for growth, yield and quality at university orchard, Tamil Nadu Agricultural University, Coimbatore, India. The genetic variability demonstrated that phenotypic coefficient of variation was higher contrasted with genotypic coefficient of variation for all the attributes in 24 genotypes. Even though PCV was more than GCV but the difference was very narrow suggesting that, there was less influence of environment. High estimations of heritability and genetic gain increase were displayed for plant height at final harvest, the number of primary branches plant -1 at final harvest, inter nodal length of main stem, stem girth, the number of flowers cluster -1 , the number of flowering clusters plant -1 , the number of fruits cluster -1 , the number of fruit cluster plant -1 , days from fruit set to fruit maturity, per cent fruit set, the number of fruits plant -1 , fruit length, fruit girth, fruit width, the number of locules fruit -1 , fruit weight, the number of seeds fruit -1 , weight of seeds fruit -1 , weight of 1000 seeds, yield plant -1 , fruit firmness, pericarp thickness, shelf life of fruits, total soluble solids, total sugars, ascorbic acid, titrable acidity, lycopene, total carotenoids, total phenol and total antioxidant. Thus, the selection might be effective for improving these traits.

“…Sugars (sucrose, fructose, and glucose), which are the primary metabolites in tomato fruit, account for about 50% of fruit dry weight (DW) (Balibrea et al., 2006; Davies et al., 1981). Tomato quality is determined by many factors, including genotype, for example, cultivar (Caretto et al., 2008; Shokat et al., 2013); environment, for example, CO 2 and drought; and management, for example, irrigation and fertilization (J. Liu et al., 2020; Wei et al., 2018). Tomato fruit quality must be improved by optimizing irrigation and fertilization under an open field and protected conditions (Hartz et al., 2005; K. Liu et al., 2011), particularly in arid and semi‐arid regions (Fereres & Soriano, 2007; Geerts and Raes, 2009), where water is the most limiting factor for crop cultivation.…”

Background The increasing concentration of atmospheric CO2 not only affects the growing environment of crops but also aggravates the global greenhouse effect and further aggravates the problem of water shortage. The combined effect of water deficit and potassium (K) application has not been widely studied. Aims A pot experiment was conducted to investigate the effect of deficit irrigation (DI) and K application at different growth stages on carbon allocation and enzyme activities related to sugar metabolism. Methods Tomatoes were transplanted and planted on April 26, 2017 and harvested on August 15, 2017. Four irrigation regimes were implemented with two water levels (full irrigation‐W and DI‐W/2) in different growth stages, and each water treatment was equally divided into two subgroups: with K (K1) and without K (K0). Fruits from the first to fourth trusses of the tomato plants were sampled. Tomato growth, carbon allocation, and related enzyme activities were measured. Results The fresh weight (FW), dry weight, and relative growth rate of dry mass were sensitive to irrigation amount under K fertilization, enhancing the promotion effect of irrigation on fruit. Meanwhile, carbon allocation was sensitive to irrigation amount under K regime. Sucrose synthase (SuSy), acid invertase (AI), and sucrose phosphate synthase (SPS) were also highly sensitive to irrigation amount under K application condition. Starch phosphorylase displayed a quadratic parabola for irrigation amount, and adenosine diphosphate glucose pyrophosphorylase (AGPase) was highly sensitive to irrigation amount without K fertilization. Carbon in the form of other carbohydrates, carbon in the form of soluble sugar (Csol), and fruit water content were the factors that had the greatest influence on the principal components. Classification by K‐means algorithm and canonical correlation analysis showed that FW, fructose, sucrose, and starch could be used as significant indicators of the dry matter components of the fruit for the treatment without K. In the case of K regime, SuSy, AGPase, AI, and Csol could be used as a significant indicator of the correlation analysis of carbon metabolism activity. Conclusions The factors related to the improvement of fruit quality and carbon allocation by deficient irrigation and K application were explored. Water stress changed the distribution of photosynthetic carbon between starch and soluble sugar. K application further changed the balance between soluble sugars and other compounds. In particular, it significantly increased the carbon content of soluble sugars and decreased that of other compounds. AI and SuSy are key enzymes affecting carbon metabolism under water‐deficient conditions.

“…In Khyber Pakhtunkhwa, area and production of tomato is 13950 hectares and 113200 tons, respectively [3]. Availability of genetic variation among different desirable and vital traits is necessary for vegetable breeder in order to develop potential materials of tomato plants through breeding and selection [4]. Many genotypes of tomato with desirable characteristics are available currently for commercial as well as home gardeners [5].…”

This experiment was carried out to assess different tomato genotypes for yield and morphological attributes at Agricultural Research Station (ARS) Swabi during 2018. Experiment was laid out in a randomized complete block design (RCBD) with three replications. Results of the experiment showed significant differences among the tomato genotypes for all parameters except days to first flower initiation. Maximum number of flowers cluster-1 (20.0 flowers) were observed for tomato genotype 006231 and maximum number of fruits inflorescence-1 (15.0) were recorded for genotypes 006231 and 00289, respectively. Maximum number of primary branches plant-1 (10.0 branches) and secondary branches plant-1 (24.0 branches) were developed by tomato genotype 017875. Bombino produced maximum fruit length (5.84 cm) and fruit diameter (4.99 cm), respectively. Highest plant height was attained by genotype 017875 (102.5 cm) while Roma produced smaller plants (49.9 cm). Maximum numbers of fruit clusters plant-1 (28.0 clusters) were produced by genotype 00289 whereas Red Wonder showed maximum fruit yield plot-1 (3.74 kg). Higher values of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were observed for number of secondary branches plant-1 (32.49% and 31.69%), number of fruit clusters plant-1 (29.03% and 25.94%), plant height (22.93% and 21.72%) and fruit yield plot-1 (42.92% and 39.63%). High broad sense heritability values were obtained for number of secondary branches plant-1 (95.1%), fruit diameter (66.8%), number of fruit clusters plant-1 (92.1%), plant height (89.7%) and fruit yield plot-1 (85.2%). On the basis of excellent performance for most of the yield and yield related parameters, the tomato genotypes Red Wonder, Bombino, 006231, 00289 and 017875 are recommended for onward use in tomato breeding programs for the development of commercial tomato varieties/hybrids.
