Title : Collaborative rice research and development thrusts between irri and Nepal Material Type: printed text Authors: Tripathi, B.P., Editor ; Gurung, H.B., Author ; Pandey, Sushil, Author ; Ladha, J.K., Author ; A Kumar, Author ; Regmi, A.P., Author ; Sherchan, D.P., Author ; AK Gautam, Author ; Akhtar, T., Author ; B.B Adhikari, Author ; K.K Dahal, Author ; H.K Panta, Author Publication Date: 2010 Pagination: 203-205 p. Abstract: The three major collaborative projects were initiated from 2005 in different Research Centres of Nepal Agricultural Research
Council (NARC) and in Lamjung site of Institute of Agriculture and Animal Sciences (IAAS), Chitwan. The overall objectives of
these projects are to increase the rice production and productivity in favorable lowlands and marginalized upland rice environments
of both plain and hills ofNepal. Baseline survey of all sites is discussed. Different Integrated Crop Management technologies in ricewheat
systems in both transplanted rice and upland rice evaluated. Farmers' field days' and trainings organized and different
Resource Conservation Technologies (RCTs) evaluated. Both lowland and upland rice varieties were tested in mother and baby
trials. Varieties suitable for both lowlands and upland rice were selected by conducting mother and baby trials as well as in Farmers'
Acceptance Test (FAT) !Minikits and Demonstrations. Farmers have saved seeds of some promising rice varieties s for planting in
the next season. Drought tolerant rice varieties received from IRRI were selected for rainfed lowland conditions of Nepal. For the
dissemination of rice technologies to different stakeholders, exposure trainings/workshops were organized for the scientists/technical
officers/technicians of NARC as well as Subject Matter Specialists (SMS)/Extension Officers of the districts/Training
Officers/Technicians of the Regional Training Centers and Regional seed, soil and plant protection technicians of different regions
of Nepal. Rice Fact Sheets prepared by the scientists were put in NARC website as Nepal Rice Knowledge Bank (NRKB) with the
help of IRRI. Rice technologies prepared by IRRl in the form of Rice Knowledge Bank (RKB) were disseminated by providing COs
to different NARC research stations, district agricultural development offices, regional directorate of agriculture and NGOs working
in rice research and development as well as to IAAS, Rampur for teaching pUiposes. With the establishment ofNepal-IRRI Office,
the technical capability of scientists and technical officers ofNARC has been further strengthened.Link for e-copy: http://elibrary.narc.gov.np/?r=1017 Collaborative rice research and development thrusts between irri and Nepal [printed text] / Tripathi, B.P., Editor ; Gurung, H.B., Author ; Pandey, Sushil, Author ; Ladha, J.K., Author ; A Kumar, Author ; Regmi, A.P., Author ; Sherchan, D.P., Author ; AK Gautam, Author ; Akhtar, T., Author ; B.B Adhikari, Author ; K.K Dahal, Author ; H.K Panta, Author . - 2010 . - 203-205 p.

Title : Development of rice varieties through introgression of elite genes from cgp and dgp lines using recurrent backcrossing with Khumal-4 and Masuli Material Type: printed text Authors: Sah, R.P. ; Koirala, K.B., Author ; Ghimire, K.H., Author ; HK Prasai, Author ; Bhandari, H.S., Author ; R Poudel, Author ; Bhattarai M, Author ; Akhtar, T., Author Pagination: 95-104 p. Languages : English (eng) Abstract: A total of 192 lines including exotic CGP and DGP received from International Rice
Research Institute (lRRl) and local sources were evaluated at Agriculture Botany Division,
Khumaltar and National Rice Research Program (NRRP), Hardinath during summer
2000-2002. A considerable variation for quantitative traits was recorded in the germplasm
evaluated Different lines have been identified as donor:s for various important agronomic
and yield contributing traits. F1s, BC1F1s, BC~1s and three-way crosses have been
developed through introgression of elite QTL from CGP and DGP lines into pcpular
commercial varieties K.humal-4 and Masuli. They will be advanced to BC~1. BC~1 and
BC-IF1 and selection for target traits in target environments will be carried out.Link for e-copy: http://elibrary.narc.gov.np/?r=1091 Development of rice varieties through introgression of elite genes from cgp and dgp lines using recurrent backcrossing with Khumal-4 and Masuli [printed text] / Sah, R.P. ; Koirala, K.B., Author ; Ghimire, K.H., Author ; HK Prasai, Author ; Bhandari, H.S., Author ; R Poudel, Author ; Bhattarai M, Author ; Akhtar, T., Author . - [s.d.] . - 95-104 p.

Title : Diallel analysis for estimation of combining ability and gene action in fine-aromatic rice Material Type: printed text Authors: Sah, R.P. ; Koirala, K.B., Author ; Ghimire, K.H., Author ; ,Thapa, B., Author ; Bhandari, H.S., Author ; Akhtar, T., Author Pagination: 105-112 p. Languages : English (eng) Abstract: Combining ability analysis was done using 10 fine-aromatic rice genotypes in a partial
diallel crossing design to estimate General Combining Ability (GCA), Specific
Combining Ability (SCA) and nature of gene· action to heip in breeding fine-aromatic
rice varieties. Ctmsiderable variation among parents and crosses (F1s) for agronomic
parameters were observed The .parental mean for panicle weight (g) was 2.83 g while
the F1s was 3.16 g with an average heterosis of 0. 3 g (11. 3%) and a maximum heterosis
of 3.17 g (112.0%). Panical weight (g) being the important yield component was
analysed to estimate GCA, SCA and gene effects. The analysis of variance revealed
significant effects (P=0.01) due to GCA and SCA. The GCA estimates of parents
ARC10863 (0. 77) and IR43850 (0.33) were significant and positive, while those of ARC
10796 (-0.20) and Khumal-4 .(-0.28) were significant (P=0.01) Q!ld negative. The
superior crosses with hi~h positive effect on panicle weight were from the abo~e parents.
The additive variance (cl A) estimate was 0.30 and that of dominance variance (rl D) was
3. 79, thereby indicating low genetic he"itability (0. 064), and presence of both additive
and non-additive gene effects on·panicle weight of fine-aromatic rice. Implications of
this study in the selection of superior parents and crosses, developing suitable breeding
strategy and approaches for increased effectiveness and efficiency in breeding have
been discussedLink for e-copy: http://elibrary.narc.gov.np/?r=1092 Diallel analysis for estimation of combining ability and gene action in fine-aromatic rice [printed text] / Sah, R.P. ; Koirala, K.B., Author ; Ghimire, K.H., Author ; ,Thapa, B., Author ; Bhandari, H.S., Author ; Akhtar, T., Author . - [s.d.] . - 105-112 p.
