QTL mapping for nine drought-responsive agronomic traits in bread wheat under irrigated and rain-fed environments
In bread wheat, QTL interval mapping was conducted for nine important drought responsive agronomic traits. For this purpose, a doubled haploid (DH) mapping population derived from Kukri/Excalibur was grown over three years at four separate locations in India, both under irrigated and rain-fed environments. Single locus analysis using composite interval mapping (CIM) allowed detection of 98 QTL,...
متن کاملModelling of Greenhouse Gas Emissions from Wheat Production in Irrigated and Rain-Fed Systems in Khorasan Razavi Province, Iran
Agriculture has a key role in greenhouse gas emissions. As such, the present study aimed to evaluate the greenhouse gas emissions from wheat production in irrigated and rain-fed systems. The primary data were collected from 116 wheat farmers. The results showed that the total greenhouse gas emissions from wheat production in irrigated and rain-fed systems were 637.8 and 65.12 kgCO2eq, respecti...
متن کاملGlobal rain-fed, irrigated, and paddy croplands: A new high resolution map derived from remote sensing, crop inventories and climate data
Irrigation accounts for 70% of global water use by humans and 33–40% of global food production comes from irrigated croplands. Accurate and timely information related to global irrigation is therefore needed to manage increasingly scarce water resources and to improve food security in the face of yield gaps, climate change and extreme events such as droughts, floods, and heat waves. Unfortunate...
متن کاملA Simple Algorithm to Identify Irrigated Croplands by Remote Sensing
− The identification of irrigated cropland is essential for crop monitoring, yield estimation and water management assessment in drylands. The standard approach is to use supervised classification on multispectral bands, vegetation indices or the Principal Components or, more recently, the combination of optical images with radar data. More complex methods, such as time-series analysis, sub-pix...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
