Abstract:
study was conducted al Bangladesh Agricultural Research Institute
(BARJ), Joydebpur, Gazipur to study the effect of grafting among three tomato
varieties for producing wilt free tomato. The treatments of the experiment
consisted of three tomato varieties viz. BARI Tomato-3, BARI Tomato-4 and
BARJ Tomato-6 and rootstock Solanum sisymbriifolium. Tomato varieties had
significant influence on grafting success, days to 50% Dowering, plant height,
days to harvest, fruit characters, bacterial wilt, virus, plant mortality and yield
contributing characters. The result of the experiment further revealed that
maximum grafting success ( 46.79%) number of fruit (26.06), yield per plant
(1.73 kg) and yield per hectare (76.36 ton) was obtained from the variety BARI
Tomato-6.Grafting had significant inlluencc on the above mentioned
parameters including incidence of bacterial will. The highest harvesting
duration (76 days), no wilt incidence and higher yield (64.32 ton/ha) were
recorded when tomato plant was grafted. Grafted tomato plants had maximum
harvest duration (76.22 days), no wilt incidence and produced higher yield.
(64.32 ton I ha) When the combined effect of varieties and rootstock were
taken into consideration, highest yield (79.74 ton/ha) was obtained from graft
BARI Tomato-6. But BARI Tornato-J had also highest yield (78.21 ton/ha) and
early harvest when it was grafted. Therefore, it may be recommended that
tomato varieties may be grafted on resistant wild Solanutn rootstocks for
controlling bacterial wilt and gelling higher yield
