Abstract:

Vegetable grafting is known as potential technology, as to conquer biotic stresses with special emphasis on diseases resistance and to enhance the yield and biochemical properties in cucurbitaceous crops. The seven cucurbit rootstocks were screened in vitro against the disease gummy stem blight by inoculating fungus Didymella bryoniae. All the rootstocks screened unveiled resistance to the fungal pathogen Didymella bryoniae. Most of the characters under investigation were significantly influenced by the interaction effect of rootstocks and grafting techniques. Treatment RS5GT3 resulted in least number of days to first flower, days to first fruit set and minimum number of days to first fruit harvest. Whereas, RS2GT3 ensued in the highest grafting success per cent i.e. 96.67%, highest number of marketable fruits per plant, highest marketable fruit yields per plant, maximum marketable fruit yield per square meter and maximum vine length. Treatment RS1GT3 ensued in the highest average fruit weight and fruit length. Lowest internodal length was perceived in treatment and highest TSS of was witnessed in treatment RS4GT2. The interaction effect of rootstocks and grafting techniques had no significant effect on fruit diameter and harvest duration. Therefore, it is accomplished from the study that splice grafting technique in combination with bottle gourd rootstock is found to be most apposite for attaining maximum production in terms of yield and for resistance against gummy stem blight under protected conditions.
