Title : Correlation and path analyses in F1 and F2 generations of garden pea Material Type: printed text Authors: D.K Choudhary, Author ; Sharma, R.R., Author Pagination: 204-206 p. Languages : English (eng) Keywords: Correlation, garden pea, path analysis Abstract: Correlation and path analyses in F1 and F2 generations among 28 crosses obtained through partial diallel crosses of 8 diverse genotypes of garden pea were studied and evaluated under randomized block design with 3 replications at Vegetable Research Farm of IARI, New Delhi during rabi season of 2000/01.

Title : Correlation and Path Coefficient Analyses in Sugarcane Material Type: printed text Authors: Chaudhary, R.R., Author ; Joshi, Bal K., Author Publication Date: 2005 Article on page: 24-27 p Languages : English (eng) Keywords: Cane yield, correlation, path coefficient, sugarcane Abstract: This study was conducted to determine the contribution of different traits to cane yield in
sugarcane (Saccharum officinarum L). Sixty-five clones were evaluated in a replicated field
experiment at Sugarcane Research Programme, Jitpur, Nepal in 2003 for six morphological characters
under irrigated conditions. Analysis of variance revealed significant differences for all the
characters studied. Cane yield showed positively and highly significant correlation with single
cane weight, stalk length and millable cane number. There was also positively significant
correlation of cane diameter and number of internode with cane yield. Length of internode had
positive non-significant correlation with cane yield. Single cane weight had the highest positive
direct effect on cane yield followed by millable cane number. Stalk diameter and stalk length was
positively and significantly correlated with cane yield, which was due to indirect effect of single
cane weight. Results indicate that the genotypes should be selected on the basis of single cane
weight and millable cane number for getting higher sugarcane yield.Link for e-copy: http://elibrary.narc.gov.np/?r=57

Title : Pollen and Spikelet Analysis in F1 Rice Hybrids and their Parents Material Type: printed text Authors: Joshi, Bal K., Author ; Laxmi P. Subedi, Author ; Santa B. Gurung, Author Publication Date: 2007 Article on page: 120-126 p General note: Research note Languages : English (eng) Keywords: Correlation, F1 rice, pollen category, regression coefficient Abstract: Pollen analysis can be used to discriminate between different species, identify possible
interspecies hybrids, identify restorer and maintainer lines, useful to study genetics of
restorer gene, interaction between chromosome and cytoplasm and relationship between
parents. Pollen abortion system of male sterility is an important tool in hybrid rice
production and spikelet is the major yield components. Nine improved cultivars, six
landraces and three wild aborted cytoplasmic-genetic male sterile (CMS) lines were used to
analyze pollen and spikelet in F1 rice hybrids and their parents. The frequency of pollen
categories and its relationship to spikelet fertility were investigated. Pollen sterility of the
F1s was determined by staining pollen grains in 1% potassium iodide-iodine (I-KI) solution.
Spikelet fertility was determined by counting the total number of seed set in proportion to
the total number of spikelets. Correlation and regression coefficients for some traits were
computed. In hybrids, pollen fertility ranged from 0.5 to 82% and spikelet fertility from 0 to
87%. Pollen fertility varied from 28 to 97%, while spikelet fertility from 73 to 91% in pollen
parents. The highest and the lowest percentages of pollen fertility were found in Chaite-6
and Chiunde cultivars respectively. Spikelet fertility percentage varied widely among
hybrids and many hybrids had lower spikelet fertility percentage than their parents.
Therefore, it is of practical importance to understand the causes of high spikelet sterility in
hybrids for possible increase in spikelet fertility. Highly significant positive correlation was
found between stained round fertile (SRF) pollen and spikelet fertility. The positive value of
correlation and regression coefficient on SRF and spikelet fertility were found between F1
and mid parent, and F1 and male parent. High fertility of cross may be due to the presence of
a wide compatibility gene or restorer genes in the cultivar. Lower pollen and spikelet
fertility of the crosses was attributed to effect of the genetic background of the tester parent.Link for e-copy: http://elibrary.narc.gov.np/?r=37

Title : Modeling of soil organic matter content from world view-2 sensor in Nayavelhani VDC of Nawalparasi District, Nepal Material Type: printed text Authors: Vaidya, S.N., Author ; K Sah, Author Pagination: 403-411 p. Languages : English (eng) Keywords: Digital number, World View-2, coefficient of the estimator, correlation, soil organic matter content. Abstract: Soil organic matter (SOM) is one of the fundamental soil properties affecting productivity of crops by controlling nutrient budgets in agricultural production systems. Visual and qualitative interpretation of air-photos is still the base of mapping of SOM as most common method. Quantitative estimation of soil organic matter content (SOM) is essential when there is scanty of soil test laboratories, its strong spatial dependence and its measurement is a time and labor-consuming procedure and emerging geographical science information technology. In the present attempt, soil organic matter content is modeled by using airborne world view-2 reflective remote sensing methodology and it was tested in Nayavelhani (62.31 sq.km) VDC of Nawalparasi district of Nepal………………….
