The development of varieties with a high content of antioxidant compounds, such as carotenoids, has become a major focus in the marketing of tomato. Several mutants have been used in the development of high pigment varieties, but the significant influence of the environment on carotenoid content and the presence of negative side effects in vegetative growth and yield have limited the success of these variants. Consequently, the identification of alternative sources of variation in the quest for high carotenoid content is ongoing. In this study, 12 accessions of Solanum lycopersicum (including the former var cerasiforme) and S. pimpinelifolium

“…In India, tomato occupies an area of 0.87 million hectares with a production of 17.50 million tonnes and productivity of 20.11 tonnes per hectare (FAO, 2012). Tomato has been identified as a functional and ''nutraceutical'' food (Canene-Adams et al, 2005;Adalid et al, 2010). A nutraceutical is any substance considered a food, or part of a food, that provides medical or health benefits, including disease prevention and treatment (Jack, 1995).…”

Abstract:In the present study, thirty accessions of tomato were evaluated for estimation of correlation and path analysis among various quantitative and qualitative characters related to fruit yield. There were highly significant differences among the accessions for all the characters studied as per the analysis of variance. Genotypic correlation coefficients were generally similar in nature and higher in magnitude than the corresponding phenotypic correlation coefficients. The results revealed that the fruit yield plant -1 was significantly and positively correlated with number of fruits plant -1 (0.3119 and 0.3184) followed by fruit set percentage (0.2434 and 0.2499), fruit weight (0.6766 and 0.6731), polar diameter of fruit (0.4687 and 0.4635) at genotypic and phenotypic level, respectively, indicating that effective improvement in fruit yield plant -1 through these characters could be achieved. Fruit weight showed positive and significant genotypic and phenotypic correlation with fruit yield plant -1 by having greatest positive direct effect (1.1298 and 1.1116) on fruit yield plant -1 at both levels, indicating the true relationship between them and the feasibility to exploit the potentiality of this trait for effective direct selection to improve fruit yield plant -1 .

-X. 2015. Insight into flower diversity in Solanum lycopersicum and Solanum chilense using comparative biological approaches. Can. J. Plant Sci. 95: 467Á478. Flowers, the defining feature of angiosperms, are reproductive organs that enable the continuation and propagation of flowering plant species. However, intra-and inter-species specific reproductive barriers have often evolved in plants; one such example being in the section Lycopersicum of the genus Solanum. This biological phenomenon is closely related to flower diversity, including visible morphologic features and processes such as pollination and fertilization are influenced by floral morphology, although the exact relationships remains unclear. In this study, two distinct Solanum accessions that exhibit either self-compatibility (SC) (S. lycopersicum, P86) or self-incompatibility (SI) (S. chilense, LA2405), from section Lycopersicum in Solanum were subjected to comparative analyses focusing on flower diversity. The long style of LA2405 was found to differ from that of P86 in that it exserts from the anther cone, and the irregular 'long strip' villi on the lower style of LA2405 were structurally distinct from the typical 'finger shape' villi of P86. Pollen grains from both LA2405 and P86 were able to germinate on their own stigmas and those of the other accessions. Pollen tube growth was arrested 1/2 and 3/4 of the way down the style in P86 and LA2405, respectively, when LA2405 was used as pistil parent. Additionally, the disappearance of starch grains and lipid bodies in the cytoplasm of the transmitting tract cells was most evident in cells that were close to the pollen tube. An analysis of the expression of flower associated genes revealed that CUL1 and SLF had an anther-specific expression pattern, while SKP1 and RBX1 were constitutively expressed in flowers of both LA2405 and P86. It was also found that transcript levels of four flower associated genes encoding subunits of the SCF complex (Skp1-Cullin1-F-box-Rbx1) were higher in anthers than in other floral organs of the flower, and higher in LA2405 than in P86. Phylogenetic analysis of CUL1 sequences and RAPD (random amplified polymorphic DNA) analysis (genome-wide scanning) indicated that flower associated genes may represent a good resource for evaluating evolutionary relationships between tomato species. Taken together the results suggest that comparative biological methods not only represent a platform for detecting evolutionary differences in flowers of different tomato species, but also provide useful data for further dissecting the mechanisms of reproductive behaviors.
