Abstract : TPS is a viable solution to mitigate the problems of non-availability of quality seed potato as the potato production through true potato seed is low cost technology and very much useful to small and marginal farmers. It reduces the burden of dependency on seed tubers. Today use of TPS is becoming popular for generating low cost quality tuberlets for planting material as well as for table use. Hybrid 92PT-27 is a high yielding and late blight resistant population which has been released for commercial cultivation in eastern region of India to meet the growing need of healthy planting material. The transplanted crop of this population gives 18-20 t/ha tuber yield with seed rate of only 150 g/ha whereas seedling tuber crop (F1C1) yields 30-35 t/ha at 90 days. The transplanted as well as tuberlet crop produces more uniform tubers, higher marketable tuber yield and possesses good keeping quality than the existing TPS populations (HPS-I/13 & TPS/C-3). The farmers can also produce TPS of this population themselves with minimal efforts as its both male (TPS/D-150) and female (83P-47) parents flowers under short day conditions.
