Title : Evaluation of True Potato Seed Families and Us Adaptability in Nepal Material Type: printed text Authors: Ram C. Adhikari, Author ; Janardan Ghimire, Author ; Gyan P. Rai, Author ; Shambhu P. Baral, Author ; Duryodhan Chaudhary, Author ; K.C.Upreti, Author Pagination: 151-161 p. Languages : English (eng) Keywords: family, nursery bed, seedling tuber, true potato seed, yield 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

Center (CIP), Lima, Peru were evaluated and compared with HPS ll/67 during the spring
season of 2002 and 2003 to see the peifomzance of TPS families for seedling transplanting for
potato production. TPS were raised in the aluminum trays and 32 days old seedlings were
transplamed in the field in randomized complete block design with four replications at
Klwmaltar, LLtlitpur. Nepal (I 360m as/). Survival of the transplanted seedlings in the field was
ranged from 72.77% to 95.84%. Late blight disease buildup in all the families was far low.
Total tuber weight, total tuber numbers and tuber numbers per plant among the TPS families
were significantly different. The ma.timum total tuber weights (2.44 kglm2
), numbers
( 129.53/nl) and ltlbers per plant ( 15.56) was produced by LT 8 x TPS 67. TPS families LT 8 x

gave the average tuber production in the ratio of29:58: 13 of over seed size (>50 g), seed size

Title : Participatory Technology Development for Sustainable Potato Production and Food Security Improvement in the Karnall Region of Nepal Material Type: printed text Authors: Giri Dhari Subedi, Author ; Shim B. Mahat, Author Pagination: 168-176 p. Languages : English (eng) Keywords: Jumla, late blight, potato clones, storage structures, true seed Abstract: A series of experiments were carried out at the Horticultural Research Station (HRS),
Rajikot, Jumla and farmers field during two consecutive years during 2006 and 2007
in order to identify suitable potato clones with good uniformity, color, shape and
resistant to pest and diseases and high productivity suitable for the Kamali region and
areas having similar agro-climatic zones of Nepal. All the experiments were designed
as Randomized Complete Block Design with three replications. The results of initial
evaluation trial (lET) revealed that clone Kufri Chipsona-2 was the highest yielder
(19.03 t/ha) followed by 394003.161 (18.57 t/ha) and 394051.4 (17.78 tlha). All the
potato clones evaluated under advance yield trial (A YT) were found comparable yield
with existing Jumla local cultivar ranging. Of six different clones tested in farmer's field
trial (FFT) clone 392222.25 was found highest yielder (13.9 t/ha) followed by Desiree
(13.8 t/ha). Out of four different true potato seed (TPS) families tested under FFT, HPS
Serana produced highest tuber yield (17.3 t/ha) followed by HPS II/67N (11.6 t/ha).
Among the storage structures tested pit storage was found to be the best store for
potato with -minimum weight loss (1.2 %) under Jumla conditions.Link for e-copy: http://elibrary.narc.gov.np/?r=241 Participatory Technology Development for Sustainable Potato Production and Food Security Improvement in the Karnall Region of Nepal [printed text] / Giri Dhari Subedi, Author ; Shim B.
