Combining ability of summer-squash lines with different degrees of parthenocarpy and PRSV-W resistance
The aim was to assess heterosis in a set of 16 summer-squash hybrids, and evaluate the combining capacity of the respective parental lines, which differed as to the degree of parthenocarpy and resistance to PRSV-W (Papaya Ringspot Virus-Watermelon strain). The hybrids were obtained using a partial diallel cross design (4 × 4). The lines of parental group I were 1 = ABX-037G-77-03-05-01-01-bulk,...
متن کاملCharacterization of Resistance to Squash Silverleaf Disorder in Summer Squash
Feeding nymphs of the silverleaf whitefly, Bemisia argentifolii (formerly known as Bemisia tabaci Gennadius, B strain), cause a physiological disorder known as squash silverleaf (SSL) in summer squash (Cucurbita pepo L.). This disorder is characterized by a progressive silvering on the upper leaf surface caused by the development of large air spaces between the palisade mesophyll cells and the ...
متن کاملTransplant Age Influences Summer Squash Growth and Yield
Greenhouse and field experiments were conducted to determine the influence of transplant age on growth and yield of ‘Dixie’ and ‘Senator’ summer squash (Cucurbita pepo L.). Dry weight and leaf area measurements indicated that 28to 35-day-old greenhouse-grown transplants grew more slowly after transplanting than plants that were 10,14, or 21 days old. Older transplants flowered earlier; however,...
متن کاملPhloem loading in squash.
Squash (Cucurbita pepo L. var. melopepo torticalis, Bailey) leaves were supplied with (14)C-sucrose, then specific radioactivities of the glucose and galactose moieties of translocated stachyose were determined. In every case, the specific radioactivity of the galactose moiety was greater than that of the glucose moiety. It is concluded that the stachyose was not synthesized at either the phloe...
