    Transmission of primary trisomics in pearl millet (1984)
    Springer
    Theoretical and applied genetics 67 (1984), S. 135-142 
    Details
    ISSN: 1432-2242
    Schlagwort(e): Chromosome transmission ; Pearl millet ; Trisomic series ; Trivalent frequency

    Thema: Biologie
    Notizen: Summary Transmission rates of extra chromosomes found in the full set of trisomics of pearl millet (Pennisetum americanum) (2n = 14) were estimated by examining the progeny of selfed trisomics and the progeny of trisomics crossed to disomics. When the trisomics were selfed, ‘dark green’ and ‘tiny’ had the highest transmission rate (23.8% and 23.3%, respectively) and ‘pseudonormal’ the lowest (13.8%). Other trisomics had an intermediate rate of transmission. When the trisomics were used as females in crosses with disomics, both ‘dark green’ and ‘tiny’ again had the highest transmission rate and ‘pseudonormal’ the lowest. When the trisomics were used as males in crosses to disomics, no trisomic was transmitted to the progeny except for ‘spindle’, and this occurred with a very low frequency (2.0%). A variation in transmission rate was observed from plant to plant and season to season for the same trisomic type. A study of the transmission rate of the extra chromosomes indicated that the following factors were probably contributing to the lower rate of transmission: small- or light-weight seeds tended to have a higher proportion of trisomics than heavier seeds; lighter seeds had a lower percentage germination; a positive and significant correlation was noticed between trivalent frequency and transmission rate. Plants with reduced vigour produced a higher frequency of trisomics. Though trisomics involving longer extra chromosomes showed a high degree of pollen and ovule sterility, they were highly transmissible. This has resulted in a close relationship between gametic sterility and transmission rate of extra chromosome.

    Tertiary trisomics of pearl millet (Pennisetum americanum (L.) K. Schum): its cytomorphology, fertility and transmission (1982)
    Springer
    Theoretical and applied genetics 63 (1982), S. 139-144 
    Details
    ISSN: 1432-2242
    Schlagwort(e): Tertiary trisomic ; Pentavalents ; Pearl millet ; Transmission of trisomics
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Summary Nineteen tertiary trisomics were isolated from some translocation heterozygotes and interchange trisomics of pearl millet. Cytological analysis of these trisomics indicates that chromosome association of trivalents, univalents and pentavalents were frequent in all the trisomics. But their ratio varied from one trisomic to the next. Other associations were relatively infrequent. The relative frequencies of 6 pentavalent configurations observed in different trisomics were studied and their probable association with mode of fertility and transmission rates have been discussed.

    Nutritional parameters and yield evaluation of newly developed genotypes of lentil (Lens culinaris Medik.) (1999)
    Springer
    Plant foods for human nutrition 54 (1999), S. 79-87 
    Details
    ISSN: 1573-9104
    Schlagwort(e): Chemical composition ; Lentil ; Metabolizable energy ; Minerals ; Seed yield ; Tannin
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft
    Notizen: Abstract Among the commonly consumed food legumes, lentils occupy an important place in human nutrition in the Indian subcontinent. Twenty-one lentil genotypes were evaluated for such nutrition related parameters as moisture, protein, crude fiber, fat, ash (total mineral matter), carbohydrates, total energy and metabolizable energy. These genotypes were also analyzed for 100-seed weight and seed yield/plant. Protein content ranged between 22.1 and 27.4% with significant differences among genotypes. Considerable variations were observed among the genotypes for calcium, phosphorus, iron and tannin contents. Large variations existed in yield and 100-seed weight of these genotypes. Seed yield/plant was not significantly correlated with any of the principal seed constituents analyzed in the present study. The genotypes, LH 97 and LH 37 were found to be better and hence could be explored for further development and selection of desirable characteristics.

    Physicochemical characteristics of flours of faba bean as influenced by processing methods (1994)
    Springer
    Plant foods for human nutrition 45 (1994), S. 371-379 
    Details
    ISSN: 1573-9104
    Schlagwort(e): Boiling ; Dehulling ; Inhibitor ; Path analysis ; Roasting ; Tannin ; Trypsin
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft
    Notizen: Abstract Wet- and dry-processing with and without heating treatments were used to dehull faba beans for preparation of flours from the cotyledons. Flour qualities were assessed by levels of tannin and trypsin inhibitor and other measures of proximate composition. High roasting temperature and shorter process time that improved the recovered cotyledon yields were verified significant by path analysis methodologies. In turn, the higher cotyledon recoveries correlated with higher protein levels and inversely with the measured tannin levels. Ash reductions were correlated to the wet processing options in hull removal while reductions in the insoluble dietary fiber were notably influenced by level of heating temperatures applied. Trypsin inhibitor levels ranged from 42 to 56% of the original with reductions tied to applications of wet and/or heat processing in each case improved by increased durations and temperatures of treatments.
