Genotype x environment interaction and stability analysis in lentil (Lens culinaris Medik.)



N.K. Yadav, S.K. Ghimire, B. P. Sah, A. Sarker, S.M. Shrestha, S.K. Sah



Genotype x environment interaction was evaluated under
eight environments during lentil growing season of 2013/14 and 2014/15
for grain yield and their component characters of twenty one promising
genotypes selected from previous trial of lentil. The variances
estimated due genotype, environment and genotype x environment
interaction were found to be different significantly for all the
characters studies indicating distinct nature of genotypes, environments
and genotype x environment interactions in phenotypic expression. High
estimates of sum of square (SS) for all the traits are expressed by
environment. The explained percentage of grain yield by environment,
genotype and genotype environment interaction were 54.86, 19.86 and
25.28 respectively. To find out the effects of GEI on grain yield and
its attributing characters, the data were subjected to Additive Main
effects and Multiplicative Interaction (AMMI) .The results finally
indicated that AMMI stability value and AMMI biplot are informative
methods to explore stability and adaptation pattern of genotypes in
practical plant breeding and in subsequent variety recommendations. In
addition, finding mega environments help to identify the most suitable
lentil cultivars that can be recommended for areas within the
mega-environment in either one or more test locations. The genotype RL39
(1.254 mt ha-1 ) and LL10071 (1.196 mt ha-1 ) produced higher grain
yield) than all other genotypes over the environments and performed
better at most of the places. The genotypes ,F2003-49L, Arun, 39-S-66L,
RL-44, and ILL10071 were found to be comparatively stable as their
performance were hardly affected by the G x E interaction and thus would
perform well across a wide range of environments. These genotypes
produced higher grain yield than all checks.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran Shadi Maleki, Abbas Mafi, Seyedeh Mahsa Hosseini Today, as an essential part and parcel of urban landscape that they play a major role in metabolism and create a lack of serious damage to urban life. This study performed to investigate the willingness of citizens to participate in activities to protect and develop landscapeof Tehran district 4. The research was descriptive and correlation method that is used for collecting information. The statistical population consisted of district 4 of Tehran. The sample size was determined 230 by using Cochrane method. A questionnaire was used to collect data. According to the research, 63.04 percent of citizens showed participation in a high level. Among the variables investigated how citizen participation in conservation and development of landscape, effective strategies to motivate citizens to participate,the reasons for la...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
