Title : Evaluation of True Potato Seed Families for Seedling Tuber Production in Nepal Material Type: printed text Authors: Adhikari, R.C., Author ; G. P. Rai, Author ; K.C.Upreti, Author ; L. P. Gautam,, Author ; Chaudhary, D.K., Author ; T. R. Chapagain, Author ; K. B. Bhandari, Author Pagination: 158-166 p. Languages : English (eng) Keywords: family, seedling tuber, true potato seed, tuber yield. Abstract: Seven hybrid true potato seed (TPS) families received from the International Potato Center,
Lima, Peru were evaluated and compared with HPS 11167 and HPS 7167 during 2001 to 2003
to see the performance of hybrid TPS families for seedling tuber p_roduction in di.fferellt agroecological
zones of Nepal. The families were tested in randomized complete block design
(RCBD) with four replications. Tuber yield produced by MF II x IPS 67 (5.12 kg/m2
) and
Atzimba x TPS 67 (3.15 kg!nl) at Khumaltar and Lumle, respectively were respectively
higher than other tested families. In Pakhribas, Surkhet and Taralu:;ra maximum tuber
weights were obtainedfromMF II x TPS 67 (3.94 kg/m2
), Serranax TPS 13 (2.24 kg!nl) and
HPS 11167 (6.20 kglm2
). Atzimba x TPS 67 produced significalltly maximum tuber number at
Khumaltar (496.47/nh Lumle (400.85/m2
) and Pakftribas conditions (349.01/m2
), whereas
in Surkhet and Tarahara, maximum tuber number were recorded in Serrana x TPS 13
(352.05/m2
) and HPS 11167 (723.67/m2
), "respectively. The average tuber weight among the
families were statistically significant, Maximum average tuber weights were recorded in LT 8
x TPS 13 in all the locations. None of the families were resistant/tolerance to late blight
(Phytophhora infestans) disease at Lumle. Based on overall performance, TPS families MF II
x TPS 67, Atzimba x TPS 67, MF II TPS 67 and HPS 7167, Serrano x TPS 13, MF II x TPS 67
and HPS 11167 were found promising for seedling tuber production in Lumle, Pakhribas,

Title : Field Evaluation of Potato Clones for the Idlls of Nepal Material Type: printed text Authors: Khatri, B.B., Author ; Shrestha, S.L., Author ; G. P. Rai, Author ; D. Chaudhari, Author Pagination: 141-145 p. Languages : English (eng) Keywords: clones, evaluation, late blight, potato, resistance Abstract: Field experiments were conducted at Khumaltar during 2001/02 and 2002103 to evaluate newly
introduced potato clones for their growth and yield characteristics. Among all the tested clones,
LBr 40, LBr 43, 396082.21, 396233.25 and Sesseni had a higher resistance against late blight
disease in the years followed by clones LBr 44, 396082.16, BSU P03, 1-1035 and 392287.48.
Variety Desiree and clones 392254.33, 396082.6 and 392247.19 were found highly susceptible
to this disease. Kufri Jyoti once recommended as resistant variety also got severely infected with
late blight disease both the years; however, the yield was not affected seriously. Clones
396082.21 and LBr 40 were two outstanding clones followed by 396233.25, BSU P03,
392236.6 and 392254.33 for the LB disease resistance and higher tuber yields. Based on
observed foliage characters, higher tuber yields and high or moderate levels of late blight
disease resistance, further on1arm testing of these clones are recommended in the hills of

Languages : English (eng) Keywords: cropping systems, intensilication, potato Abstract: Studies were undertaken in Juwanetar site of Kabltrepalanchok distlict and Naldung site of
Bhaktapur district during 2001/02 and 2002103 to idemify improved potato varieties and
illtroduce improved cultural practices suitable in the rice-wheat cropping systems prevailing in
the mid-hills of Nepal. In Juwanetar site, results showed that the impiVved varieties (Janak Dev,
Kimma/ Red, NPI 106 ad Kufti Jyoti) cultivated either i11 recommended practice or in farmers'
practice, both were found more beneficial to the farmers compared to the local check (md as a ·
result, 30% more yield was obtained by adopting it i11 paddy-potato-maize cropping systems. In
Naldung site, varieties 378711.7, 392207.4 and Desiree as a first crop (awumn season) and
valieties 378711.7 and 388764.26/JJ as a second crop (spring season) were found highly
suitable to intensify in paddy-potato-potato or paddy-potato-wheat cropping systems. giving
significantly higher tuber yields and fit to the cropping systems. Yield pe1jormance and disease

Title : Performance of In-Vitro Plantlets and Stem Cuttings for Pre-Basic Seed Potato Production Under Glasshouse Material Type: printed text Authors: Sakha, B.M., Author ; G. P. Rai, Author Pagination: 186-189 p. Languages : English (eng) Keywords: cardinal. In vitro, mini tubers, PBS, plant geometry, stem cuttings Abstract: Four weeks old in t;itro plantlets and stem cuttings of potato cv. Cardinal were plallted under
glasshouse with three plallf geomett)'· viz. 1 OxJO em. 1 5x I 5 em and 20x I 0 em to study the
petformance of theie plallfing materials for pre-basic seed (PBS) production. The study was
conducted in RCBD replicated thrice and the data analyzed with MSTAT-C. It was fotmd that
in vitro plantlers produced five minitttbers per plant as compared to two from stem cuttings.
However, the mean tuber size of PBS produced from stem cuttings was 8. 7 as against 2.8 g
produced from in vitro plantlets. The plantlets planted with 10x10 em spacing yielded the
highest number (294/nl) of PBS. Hence 10 x 10 em spacing is recommended for in vitro
plantlets to maximize the mm1ber of PBS yield and for stem cuttings to maximize minituber
yield as well as minimize the mean minituber size.Link for e-copy: http://elibrary.narc.gov.np/?r=488 Performance of In-Vitro Plantlets and Stem Cuttings for Pre-Basic Seed Potato Production Under Glasshouse [printed text] / Sakha, B.M., Author ; G. P. Rai, Author . - [s.d.] . - 186-189 p.
