“…Nevertheless, this fluctuation is usual in compounds such as l-ascorbic acid, so prone to environmental effects. As an example, the cultivar DoubleRich developed from crosses with S. peruvianum has been reported to have contents from 318 mg kg −1 (Watada et al, 1976) to 500 mg kg −1 (Stevens and Rick, 1986). Several aspects explain these large variation levels, with temperature and mainly sun radiation playing a predominant role in ascorbic acid accumulation (reviewed in Dumas et al, 2003).…”

“…It should be noted that especially high values of l-ascorbic acid have been also detected in other related wild species such as S. pennelli (Di Matteo et al, 2010) or S. peruvianum (Stevens and Rick, 1986), but considering their genetic distance with cultivated tomato, and especially the great differences in fruit organoleptic quality, it is much more difficult to exploit these sources of variation. In this sense, in crosses of cultivated tomato with S. pennellii, the hybrids only increased a 20% of the wild parent potential (Di Matteo et al, 2010).…”

“…Additionally, a deleterious effect of plant yield has been described for this type of high vitamin C cultivars due primarily to a reduction in fruit size (Stevens and 0304-4238/$ -see front matter © 2011 Elsevier B.V. All rights reserved. doi:10.1016/j.scienta.2011.10.013 Rick, 1986). Something similar applies to cultivars carrying the high pigment mutation, linked to high carotenoid and l-ascorbic acid contents that show important yield reductions (Stommel, 2006).…”

“…Wild relative species such as Solanum peruvianum L., Solanum pennellii Correll or Solanum pimpinellifolium L. have been found to be good sources of high ascorbic acid content (Stevens and Rick, 1986;Di Matteo et al, 2010;Roselló et al, 2011). In fact, cultivars such as Doublerich, derived from S. peruvianum, have been developed and commercialized as high vitamin C tomatoes.…”

a b s t r a c tThe genotypic potential for high l-ascorbic acid content of 15 accessions of S. lycopersicon and S. pimpinellifolium has been evaluated in three environments, including open-air and glasshouse cultivation and two localities. The environmental effect on l-ascorbic acid accumulation was highly genotype-dependant and the variance ascribed to the G×E environment was similar in importance to that ascribed to genotype. The variation found within accession might be ascribed to microenvironmental effects associated with temperature changes and oxidative stress or population variability. Several accessions with high genotypic values ( +G) have been identified. Among them, accession PI365959 of S. pimpinellifolium, showed a genotypic value of 293.8 mg kg −1 , statistically significant higher (P < 0.05) than the genotypic potential of controls reported to have high l-ascorbic content (CDP4777, 115.0 mg kg −1 ). It also showed positive G×E interactions, with a relatively high stability. Accession LA1423 of S. lycopersicon var. cerasiforme, despite being less stable, had also high genotypic values for l-ascorbic acid accumulation (197.4 mg kg −1 ). This germplasm will be of great interest for the development of new tomato cultivars targeted to added-value markets appreciating nutritional or functional quality. The close relationship of the selected material with the cultivated tomato will enable an efficient and rapid exploitation of their potential in breeding programmes.

“…Male sterility, which in tomato is controlled by a single recessive gene, reduces the cost of hybrid seed production by eliminating the need to emasculate the female parent prior to anthesis (Rick & Robinson, 1951;Lapushner & Frankel, 1967;Scott et at., 1980;Yordanov, 1983;Stevens & Rick, 1986). …”

Effects of the ms10 gene, polygenes and their interaction on pistil and anther-cone lengths in tomato flowers

et al. 1994

Pistil and anther-cone lengths (PL and AL) are important traits in tomato hybrid seed production with the use of male-sterile flowers and in fruit production of fertile plants under high temperature. The effects of the male sterility gene mslO, polygenes, and their interaction on tomato PL and AL and on the difference between them (DIF) were studied in two experimental populations, each obtained from a different cross and comprised of F3 families derived from selfed heterozygous (MslO/mslO) F2 plants. Data were analysed using a mixed model for a single gene, polygenes, and their interaction. The presence of the mslO gene resulted in AL and PL that were shorter by 2.5 (± 0.1) mm and 1.2 (± 0.1) mm, respectively, in male-sterile flowers than in male-fertile ones. Thus DIF was greater by 1.3 (± 0.1) mm in male-sterile flowers than in male-fertile flowers. 'Main polygenic variance' was found in all three traits. The variance due to interaction between polygenes and the ms]O gene, even when significant, was always smaller than the variance due to polygenes alone, or to environment. Emasculation of the msiO male-sterile parent appears to be unavoidable for the efficient production of hybrid seeds.
