    Improvement of tomato flavor by genetically increasing sugar and acid contents (1983)
    Springer
    Euphytica 32 (1983), S. 845-855

    ISSN: 1573-5060
    Keywords: Lycopersicon esculentum ; tomato ; flavor ; sensory evaluation ; soluble solids

    Notes: Summary Advanced high sugar and acid breeding lines of tomatoes (Lycopersion esculentum Mill.) were rated higher in sweetness, sourness and overall flavor intensity than the standard cultivars Cal Ace or T3. Titratable acidity and soluble solids content were major contributors to differences in overall flavor intensity. The results demonstrate that significant improvement in tomato flavor can be attained by increasing sugar and acid contents in tomato fruits by genetic manipulation. Current evidence indicates that breeding for high soluble solids in horticulturally acceptable tomato cultivars is justified.

    High salt tolerance potential in Lycopersicon species during germination (1986)
    Springer
    Euphytica 35 (1986), S. 575-582 
    Details
    ISSN: 1573-5060
    Keywords: Lycopersicon ; tomato ; salinity ; germination ; germplasm ; breeding ; salt-tolerance
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The potential to improve seed germination responses to salinity was evaluated for 13 accessions representing six wild Lycopersicon species and 20 accessions of L. esculentum. Germination response times increased in all accessions at 100 mM NaCl. Analysis indicated that one accession of L. peruvianum (PI126435) germinated faster under high salinity than all other accessions and was closely followed by L. pennellii (LA716). The fastest germinating L. esculentum accession, PI174263, ranked third. Additional wild ecotypes exhibiting rapid germination at 100 mM NaCl were identified among L. pimpinellifolium and L. peruvianum.

    Low temperature seed germination of Lycopersicon species evaluated by survival analysis (1982)
    Springer
    Euphytica 31 (1982), S. 869-883 
    Details
    ISSN: 1573-5060
    Keywords: Lycopersicon ; tomato ; low temperature germination ; survival analysis ; high altitude ecotypes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Low temperature germination responses were evaluated for 18 high altitude accessions representing five wild Lycopersicon species and 19 accessions of L. esculentum which have reputed ability to germinate in the cold. Survival analysis indicated that one accession of L. chilense germinates better at 10°C than PI 120256, the fastest-germinating L. esculentum genotype, and that PI 120256 germinates as well as PI 126435 (L. peruvianum). Additional wild ecotypes exhibiting rapid germination at 10°C were identified from L. peruvianum and L. hirsutum. These ecotypes may possess genetic potential for introgressing cold germination ability into L. esculentum cultivars.

    A greenhouse screening method forPyrenochaeta lycopersici resistance in tomatoes (1989)
    Springer
    Euphytica 40 (1989), S. 187-191

    ISSN: 1573-5060
    Keywords: Lycopersicon esculentum ; tomato ; Pyrenochaeta lycopersici ; corky root ; brown root rot ; resistance ; greenhouse screening method

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary A greenhouse screening method for corky root (Pyrenochaeta lycopersici) resistance in the tomato (Lycopersicon esculentum) is described in detail. In determining the reliability of the method, known resistance sources within wild asccessions, commerical cultivars and breeding lines were evaluated for resistance in fields naturally infested with corky root and their response compared under greenhouse conditions in soil heavily infested with corky root and artifically maintained at temperatures between 10–13°C. The procedure developed can be used year round and improves the efficiency of recovering resistant progeny in large segregrating populations.

    Generation means analysis of right-censored response-time traits: Low temperature seed germination in tomato (1990)
    Springer
    Euphytica 48 (1990), S. 239-244 
    Details
    ISSN: 1573-5060
    Keywords: Lycopersicon esculentum ; tomato ; cold tolerance ; seed germination ; genetic analysis ; missing data ; response-time data
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary In studies to determine the inheritance of response-time traits, such as time to seed germination, some viable individuals may fail to respond during an experiment. If these right-censored observations are ignored, sample means and variances will be underestimated. This is illustrated using data from time to seed germination at 9°C for Lycopersicon esculentum (Mill.) fast germinating PI 120256, slow-germinating T3 and their reciprocal F1, F2 and backcross progeny. This paper presents methods to detect and to accommodate right-censored data in generation means analysis. Genetic interpretations derived from corrected and uncorrected estimates of generation means and variances are compared. Correction for right-censoring increased estimates of environmental and phenotypic variances, and decreased heritability estimates.

    An infrared spectroscopic study of changes in unsaturation resulting from irradiation of isotropic and uniaxially oriented polyethylene films in the presence of acetylene (1994)

    Notes: Interchain bridges of unsaturated double bonds have been proposed to form in amorphous regions, when polyethylene is irradiated in the presence of acetylene. We have corroborated the formation of these bridges by infrared spectroscopic studies. The double bonds are composed mainly of trans-olefin and vinyl end groups, formed as a result of competing radical-radical termination and hydrogen atom abstraction reactions. The hydrogen atom abstraction reaction becomes insignificant in uniaxially oriented high-density polyethylene having a draw ratio of 7.5, because of the alignment and positioning of the initiating radical pairs. During in vacuo irradiation and annealing only in-chain trans-olefins are usually formed. © 1994 John Wiley & Sons, Inc.
