| Abstract: |
The major constraints for production of potatoes in Nepal are the poor quality and high
cost of seed tubers. Most successful and widely adoptable methodology in TPS has
been the use of seedling ·tubers for raising commercial crop. Twenty TPS families
received from International Potato Center Lima Peru were evaluated at National Potato
Research Program, Khumaltar, Agriculture Research Station Belachapi and Agriculture ·
Research Station Malepatan during 2005 and 2006 to see their performance. The
families were tested . in randomized complete block design (RCBD) with three
replications. TPS family C95 LB 22.2 x TP$ 67 and HPS IV67 significantly .produced
the maximum tuber yield 5.4 kg/rrf and 7. 03 kg/rrf at Khumaltar and Belachapi,
respectively in the nursery beds in 2005. But, in 2006 significantly maximum
seedling tuber yield 7.90 kglrrf, 5.04 kg/rrf and 4. 76 kg/rrf w~s obtained from
C96H 10.25 x TPS 13, FLS 15 x TPS 67 and FLS 12 x TPS 67 at Khuma/tar,
Malepatan and Belachapi, respectively. In commercial crop, F1C1 tuberlets or
C96H 13.29 x TPS 67 and FLS 12 x TPS 13 significantly produced the m_aximum tuber
yield (20.73 kg/7.2 rrf and 14.02 kg/7.2 rrf) at Khumaltar and Belachapi, respectively
as compared to Desiree (12. 17 kg/7.2 rrf at Khumaltar) and Lalgulab {5.87 kg/7.2 rr( at
Belachapi). Based on overall performance the results· suggest that the. hybrid TPS
families produce equal. or higher tuber yield as compared to standard clonal varieties. |
