Abstract:
A grafting study was conducted with three rootstocks
viz.,
Solanum torvum, Solanum sisymbrifolium and
Solanum capsicoides and two scion
viz., TNAU tomato hybrid CO 3 and Shivam. Among the rootstocks
Solanum capsicoides took less time to germinate and germination percentage was more in
Solanum sisymbrifolium both at 15 and 25 days after sowing. Success percentage was more in graft combination of Shivam with
Solanum sisymbrifolium on 30th and 45th day. The highest plant height was observed in Shivam grafted with
Solanum torvum rootstock, whereas total number of branches per plant, days to first flowering, per cent fruit set and yield per plant was high in TNAU tomato hybrid CO 3 grafted with
Solanum sisymbrifolium rootstock
. Days to fifty percent flowering and fruit weight was positive in non-grafted Shivam compared to other treatments. Days to first fruit set was observed earlier in non-grafted tomato hybrid CO 3. The combination of TNAU tomato hybrid CO 3 grafted with
Solanum sisymbrifolium rootstock performed well under field condition for yield and yield contributing characters.
