Evidence for genotypic differences among elite lines of common bean in the ability to remobilize photosynthate to increase yield under drought
Common bean (Phaseolus vulgaris L.) is the most important food legume for human consumption. Drought stress is the major abiotic stress limitation of bean yields in smallholder farming systems worldwide. The current work ...
Analysis of genetic variability and genotype 3 environment interactions for iron and zinc content among diverse genotypes of lentil
Deficiencies of iron (Fe) and zinc (Zn) are major problems in developing countries especially for woman and preschool children. Biofortification of staple food crops is a sustainable approach to improve human mineral intake ...
Study of Secondary Endosymbionts of Whiteflies Collected from Cotton Growing Districts of Punjab, Pakistan
Whitefly is the insect vector for cotton leaf curl disease. Like many arthropods, whitefly possess
different primary and secondary endosymbionts depending on ecological zone and biotype. These
endosymbionts play important ...
Effects of genetic changes to the begomovirus/betasatellite complex causing cotton leaf curl disease in South Asia post-resistance breaking
Cotton leaf curl disease (CLCuD) has been a problem for cotton production across Pakistan and north-eastern India since the early 1990s. The appearance of the disease has been attributed to the introduction, and near ...
First Report of Chilli leaf curl virus and Associated Alpha- and Beta-satellite DNAs Infecting Nettle Weed (Urtica dioica) in Pakistan
Weeds act as reservoirs of begomoviruses and ‘‘mixing vessels’’ leading to emergence of new viruses that may infect crops once a susceptible host plant is introduced into an agro-ecological system. Owing to the importance ...
Productivity enhancement of salt-affected environments through crop diversification
Recent trends and future demographic projections suggest that the need to produce more food and fibre will necessitate effective utilization of salt-affected land and saline water resources. Currently at least 20 per cent ...
Marketing of goat and sheep skins in highland Balochistan, Pakistan
This study investigated the market of skins of small ruminants through interviews with market agents in highland Balochistan. Two major factors affected skin prices: seasonality and animal species. Prices for sheep and ...
Improved water-management practices and their impact on food security and poverty: empirical evidence from rural Pakistan
Using a comprehensive data set collected through field survey of 950 farmers across Pakistan, the current study evaluates water-management practices and their impact on food security and poverty. The results show that rural ...
A SWAT modeling approach to assess the impact of climate change on consumptive water use in Lower Chenab Canal area of Indus basin
Accurate assessment of spatio-temporal variations of consumptive water use (CWU) in large
irrigation schemes is crucial for several hydrological applications. This study is designed to evaluate
the impact of climate change ...
Genetic Diversity of Bread Wheat Lines Based on Agro-morphological Traits
Twenty spring bread wheat genotypes (G) from eleven research centers in Pakistan were included in national uniform wheat yield trial (NUWYT) conducted at the Agriculture Research Farm of The University of Agriculture, ...
