The only cucurbitacin identified in Cucumis sativus is cucurbitacin C. The bitter taste of cucumber has been correlated with resistance to the spider mite Tetranychus urticae, but a quantitative relationship has not been established. We determined the spider mite resistance and

Several different fungal pathogens cause similar symptoms, which are collectively known as black spot diseases. We identified Alternaria radicina, A. dauci and Rhexocercosporidium carotae (syn. Acrothecium carotae) as the most prevalent black spot pathogens. We developed laboratory test methods for resistance to A. radicina and R. carotae, and assessed resistance in a collection of cultivated varieties and more exotic material.1

In a first grafting experiment with five rootstocks and three scions different rootstocks led to differences in growth and production of the scion. No interaction was found between scion and rootstock effects with respect to growth and production. Further experiments involved 21 and nine rootstock accessions, respectively, and scion genotype cultivar 'Corona'. During winter cultivation the rootstocks cultivars 'Renova' and 'Esvier' significantly promoted vegetative growth of the scion and rootstock Code E induced a significantly higher fruit yield than the standard rootstock 'Corona'. During summer cultivation, rootstocks of cultivar 'Glabrous' promoted maximal vegetative growth of the scion, and rootstock Code D induced the highest fruit yield. During winter cultivation early fruit production correlated well with vegetative growth induced by the rootstock, but this correlation was almost absent during cultivation in the summer. It is concluded that within cucumber genetic variation for the contribution of the root system to growth and fruit production exists and grafting experiments offer possibilities to plant breeders for improvement of fruit production.

The powdery mildew resistant, leaf chlorosis sensitive hybrid variety 'Profito' was crossed with the powdery mildew susceptible, non chlorosis sensitive hybrid variety `Corona' . Forty four F6 inbred lines of this cross, produced by single seed descent, were tested for powdery mildew resistance (PMR) and leaf chlorosis sensitivity (LCS) . PMR and LCS were positively correlated (r = 0 .59) . One or more of the PMR genes probably causes LCS as a pleiotropic effect or is closely linked to LCS, but also other factors, not genetically linked to PMR can cause LCS . Five F6 lines combined a significantly higher level of PMR than `Corona' with a significantly lower LCS than 'Profito' . Three of these lines could hardly be distinguished from `Corona' for the level of LCS .
