Title : Evaluation of Genotypes of Gladiolus for Vegetative and Floral Traits Material Type: printed text Authors: Tul B. Poon, Author ; T.M. Rao, Author ; D.P. Kumar, Author Publication Date: 2012 Article on page: 13-26 p. Languages : English (eng) Keywords: Corms, Evaluation, Genotype, florets, spikes, sprouting, traits, vase life Abstract: An experiment was conducted at Indian Institute of Horticultural Research,
Bangalore, India to evaluate vegetative and floral traits of 21 genotypes.
Sprouting per cent of corms was the highest in two genotypes ‘Shobha’ and ‘H.
S. 82-11-27’ (100 %) whereas low in ‘H.S. 84-7-11’ (68.5 %), ‘Gladiolus
callianthus’ (70.6 %), and ‘Arka Kesar’ (76.5%). Day to sprouting was early in
‘H. S. 86-32-11’ (11.2 days), ‘Shobha’ (12 days) and ‘H. S. 87-22-1’ (12.2 days)
but ‘Gladiolus callianthus’ recorded the maximum days to sprouting (30.0 days).
Day to flowering was early in ‘H.S. 88-10-22’ (64.6), ‘Shobha’ (65.8 days) and
‘H.S. 84-7-11’ (66.1 days) while late in ‘H.S. 84-4-9’ (92.6) ‘Tilak’ (91 days)
and ‘Gladiolus callianthus’ (87.1 days). The genotype ‘Gladiolus callianthus’
recorded the shortest plant (94.8cm) followed by ‘Hybrid selection 84-4-9’
(102.6cm) and ‘Kum Kum’ (106.7cm) whereas the tallest plant in ‘Poonam’
(149.1cm), ‘Shobha’ (146.9cm) and ‘Pink Friendship’ (142.1cm. The genotype
‘Arka Kesar’ recorded the highest number of florets per spike (18.1) but
‘Gladiolus callianthus’ was with the least florets per spike (9.8). Numbers of
marketable spikes per corm were high in ‘Psittacinus hybrid’ (2.0) ‘H.S. 87-22-
1’ (1.9) and ‘H.S. 88-4-8’ (1.9), ‘H.S. 82-11-27’ (1.9) and ’Kum Kum’ (1.7).
‘H.S. 87-22-1’ had long vase life (8.8 days) followed by ‘H.S. 82-11-27’ (8.4
days) while ‘H. S. 88-4-8’ had the shortest vase life (6.2 days). In respect of
most traits, 'H.S.87-22-7' is proven as the most promising genotype as
comparing against the rest of twenty genotypes. In addition, Gladiolus
callianthus and Psittacinus hybrid are two different species that can be utilized
in interspecific hybridization.

[article]
Title : Genetic Diversity in Nepalese Wheat Cultivars Based on Agro-Morphological Traits and Coefficients of Parentage Material Type: printed text Authors: Joshi, Bal K., Author ; Ashok Mudwari, Author ; Bhatta, M.R., Author Publication Date: 2004 Article on page: 7-17 p Languages : English (eng) Keywords: Agromorphological traits, coefficient of parentage, genetic diversity, Nepalese wheat cultivars Abstract: Genetic diversity between parents is necessary to derive transgenic segregants from a cross.
Coefficient of parentage (COP) and agromorphological traits (AMT) can be used to estimate
diversity among cultivars. The pedigrees of 26 bread wheat cultivars were traced back to 77
ancestors and computed coefficient of parentage for all pair-wise combinations. All the cultivars
used in the pedigree analysis were evaluated for six agromorphological traits in the National
Wheat Research Programme (NWRP), Bhairahawa, Nepal in 1996. Six quantitative variables were
used to compute dissimilarity distance matrix. Cluster and principal components analyses were
performed on the matrix of COP and AMT values. COP matrix and the matrix based on
agromorphological traits were compared. Mexico, India and Nepal were countries of the origin for
26 cultivars. A total of 77 ancestors originated from 22 different countries were used to develop
these cultivars. Most of the ancestors were aestivum (80.52%) and spring growth habit (64.94%).
Maximum dissimilarity was between RR 21 and Annapurna 3 and the most closely related pair
was Rohini and BL 1022 based on the AMT. The mean of COP for all cultivars was 0.159
0.256. The highest COP was between Annapurna 3 and Annapurna 2. Other more closely related
pairs based on COP were Kalyansona and Annapurna 2, Pasang Lhamu and Annapurna 3, UP 262
and RR 21, Vaskar and Kalyansona, NL 297 and BL 1473, Pasang Lhamu and Annapurna 1.
Completely unrelated pairs were L 52 and HD 1982, L 52 and Kalyansona, LR 64 and
Kalyansona, Kalyansona and HD 1982, PI and Kalyansona, PI and L 52, RR 21 and HD 1982, RR
21 and Kalyansona, RR 21 and PI. Fifteen ancestors were present in at least about 65% of the
cultivars. 17 ancestors had been used more frequently. Five and six clusters were formed based on
AMT and COP, respectively. Correlation coefficient between COP and AMT was 0.18 (P =
0.0168). Cultivars surveyed represent a wide range of variation for different areas of origin and
adaptation. This genetic variation may be useful for further improvement of wheat and it is
necessary to conserve them.Link for e-copy: http://elibrary.narc.gov.np/?r=72

Title : Performance of bush type French bean in the hills of Nepal Material Type: printed text Authors: Paudel, K.B., Author ; J.N. Chaudhary, Author ; Gautam, I.P., Author ; K.P Upadhaya, Author ; B Khatri, Author Pagination: 227-234 p. Languages : English (eng) Keywords: Agromorphological traits, french bean, hilly areas Abstract: Eight genotypes of bush type French bean collected from Mustang, Myagdi and Kaski, Nepal and nine genotypes introduced from the USA were evaluated under observation nursery at Rising Patan (450 masl), Tanahu, Outreach Research (OR) site of Agriculture Research Station (ARS), Lumle, Kaski during post monsoon of 2000. The promising entries from observation nurseries were evaluated under co-ordinated varietal trial at Rising Patan, ARS, Pakhribas and ARS, Lumle during spring season (February 2001), summer seasons (April 2001) and pre and post-monsoon season (April and August 2001) respectively. The performances of these genotypes were almost similar at all locations. The most promising genotypes were LB-25, LB-27, S-9 and Pant Anupama in terms of yield and other horticultural traits. Considering overall performance, pod length, pod diameter, fibre content, marketable fresh pods yield and resistant to bean rust, genotype LB-25 was superior among the tested genotypes.
