Title : Hill goat selection programme in the Eastern Nepal Material Type: printed text Authors: Pokharel, P.K., Author Pagination: 345p. Languages : English (eng) Keywords: Hill goal, Eastern Nepal, selection Abstract: An attempt for the first time ever in the livestock species has been made to enrich the production potentiality of hill goat through selective breeding. Two tier open nucleus breeding scheme has been assiduously applied in order to enhance the genetic gain. Response of selection for the first generation kids in nucleus flock at station was found to be 7.9 and 4.7 percent generation for 4 and 6-month weights respectively. Similarly, twinning ability of hill goats for the period was increased by 0.73 percent reaching the level of 68.75. In on-farm condition response of selection for first generation kids per year was 0.22, 7.01 and 7.41 percent for birth, 4 and 6 month weights respectively. Likewise, twining frequency was improved by 27 percent indicating the level of 55. In both low and mid altitudes (up to 1700 masl) of eastern hill the selection programme was found effective for improving the productivity of local hill goats.

Title : Population improvement of yellow and white maize through reciprocal recurrent selection Material Type: printed text Authors: Koirala, K.B., Editor ; Gurung D.B. ; B Bhandari, Author ; J.B Chhetri, Author Pagination: 130-154 p. Keywords: Maize ; Population reciprocal recurrent selection Abstract: Improvement through recurrent selection is one of the best methods to increase the
frequency of favorable alleles, improve cross-bred performance and tolerance to inbreeding
of the maize population. Population improvement in any maize breeding program is a must
to develop hybrids, composites, synthetics and inbred lines regularly and simultaneously. In
case of yellow maize, in 2068/69, 48 best plants from each heterotic group A and B were
selected and selfed. In case of white maize, in 2068/69, 13 best plants of Manakamana-3
and 44 plants in Deuti were selected and selfed. In 2069170, each S 1 was planted in a
separate row. Pollen grains of opposite heterotic group were bulked and crossed to opposite
heterotic group and vice versa. Similarly, pollen grains of 13 selfed lines of Deuti were
bulked and crossed to 44 selfed lines of Manakamana-3 and vice versa. Besides reciprocal
crosses, in each line 3 plants were selected to self-pollinate it. Crosses of Heterotic Group
A, B, Manakamana-3 and Deuti will be evaluated in the next season.Population improvement of yellow and white maize through reciprocal recurrent selection [printed text] / Koirala, K.B., Editor ; Gurung D.B. ; B Bhandari, Author ; J.B Chhetri, Author . - [s.d.] . - 130-154 p.

Title : Early and extra meturing maize variety for terai , inner terai and foot hill of Nepal Material Type: printed text Authors: Kunwar, C.B., Editor ; S.P Paudel ; Shrestha, J., Author ; Bhurer, K.P., Author ; J.B Chhetri Pagination: 78-81 p. Keywords: Population improvement ; half sib family selection early maize Abstract: Four field experiments (IYTE,CVTE, CFFTE, Population improvement) were conducted at
different locations during summer and winter of2009, 2010 and 2011 with the objective of
identifying and developing high yielding, insect pest tolerance, early maturing matching to
cropping system (as three crops for a year) maize varieties for hill, terai and inner terai of
Nepal. In IYTE, the genotypes S03TEYILN (5276 kg -ha), ACROSS-2401 (4605 kg -ha),
S03TEY-FM (ER), (4.518tlha) and S03TEY-SEQ (4126 kg -ha) were promising for grain
yield and maturity period; therefore they were promoted to CVT. In CVTE, the genotypes:
POP-44 I POOL-15 (3841 kg-ha), Khumal Y/ POOL-17 (3699 kg-ha) and POP-45/POOL-17
(3346 kg-ha) were noted high yielding with early maturity over the locations and Arun-lEV,
Arun-4 were promoted to CFFTE. In CFFTE, the genotypes: Arun-1 Ev and Arun-4 were
significantly superior over other genotypes and Pool-17 was the earliest in maturity. Hence,
Arun-lEV (white) and Arun-4 (yellow) and Pool-17 were already proposed for variety
release for general cultivation as early and Pool-17 as extra- early. Two cycles of
population improvement for Arun-4, Arun-1EV and Pool-17 have been completed by
adopting half-sib family selection method. Stratified mass selection was used for
maintenance and improvement of promising prerelease/released varieties.Link for e-copy: http://elibrary.narc.gov.np/?r=933 Early and extra meturing maize variety for terai , inner terai and foot hill of Nepal [printed text] / Kunwar, C.B., Editor ; S.P Paudel ; Shrestha, J., Author ; Bhurer, K.P., Author ; J.B Chhetri . - [s.d.] . - 78-81 p.

Title : Performance of widely adapted maize varieties throughout the year in relation with daily maximum temperature at Rampur, Chitwan, Nepal Material Type: printed text Authors: Balaram Bhandari ; Dil Bahadur Gurung, Author ; Ghanashyam Bhandari, Author Pagination: 163-168 p. Languages : English (eng) Keywords: climatic pattern ; yield selection temperature Abstract: Climatic parameters varies from time to time and from place to place. Desirable varieties are
those which can perform better on wider range of climatic conditions. This research was done
to assess the yield response of widely adapted early (Arun -2) and full season (Rampur
Composite) maize varieties throughout the year in relation with the pattern of daily maximum
temperature. Fifty two times of planting were done at an interval of a week in 2009/10 and
20 I 0/11. In first year, both early and full season variety produced the highest yield at 391
h
planting. Similarly, in second year, both varieties produced the highest yield at 12'h planting.
Pattern of daily maximum temperature responsible for the highest yield of early and full
season maize was analyzed. It showed that the range of maximum temperature between 30
and 35°C in most of its growth period is suitable for maize to obtain the highest yield. These
patterns may be also useful in selection of newly emerging widely adaptable maize OPVs and
hybrids.Link for e-copy: http://elibrary.narc.gov.np/?r=883 Performance of widely adapted maize varieties throughout the year in relation with daily maximum temperature at Rampur, Chitwan, Nepal [printed text] / Balaram Bhandari ; Dil Bahadur Gurung, Author ; Ghanashyam Bhandari, Author . - [s.d.] . - 163-168 p.
