Meiosis is the least explored stage for thermotolerance in wheat. We evaluated impact of 5 d moderate transient daily heat stress during meiosis main stem spike on physiological and grain yield traits 30 diverse wheat cultivars which vary widely tolerance sensitivity. found that a event had lasting impacts plant growth reproduction heat-sensitive, but not heat-tolerant, cultivars. Heat-tolerant...

Wheat starch development is a complex process and is markedly difference by changes in spikelet spatial position. The present study deals with endosperm starch granule distribution and spatial position during filling development. The study was conducted with pure starch isolated from wheat (Triticum aestivum L.), Jimai20 and Shannong1391, at 7-35 days after anthesis (DAA). The results showed th...

water logging stress is one of the most important factors which affect wheat production particularly in western regions of golestan province. this experiment was carried out in order to evaluate of six genotypes (n-81-18, arta, moghan, n-80-19, urwyt-82-11 and urwyt-82-17) of bread wheat in water logging condition at 2006-2007 growing season in gorgan agricultural research station. the experime...

mapping the QTLs of agronomic and physiological traits, 149 double haploid (DH) lines from a cross between an Australian cultivar, Clipper (salt susceptible), and an Algerian landrace, Sahara3771 (salt tolerant), were evaluated under natural saline (Yazd Station, ECsoil=10-12.8 ds/m and ECwater= 9-10 ds/m) and normal (Karaj Station, ECsoil and ECwater ~2-2.5 ds/m) environments. There were remar...

The present research was carried out at the Breeder Seed Production Unit, JNKVV, Jabalpur, Madhya Pradesh using twenty-one sets of bread wheat genotypes. These were sown and evaluated under timely condition in a randomized complete block design with three replication during post-rainy season 2021- In investigation thirteen morphological one biochemical trait analyzed. analysis variance indicate...

A field experiment was conducted inside a temperature gradient tunnel (TGT) at the ICAR-Indian Agricultural Research Institute, New Delhi during rabi 2014-15 to quantify impacts of elevated on thermal requirement, growth and yield wheat crop. Wheat crop subjected five treatments, i.e. +0ºC (representing ambient condition), +0.9ºC, +2.5ºC, +2.8ºC +3.5ºC.Temperature elevation 3.5°C increased accu...

to study the effect of sowing date and a single irrigation (si) on yield and yield components of barley, a field experiment was conducted in dryland agricultural research institute (maragheh, iran) in 2004-06 cropping seasons, using a split plot based on a randomized complete block design with 3 replications. main plots were assigned to 3 levels of sowing date (early, normal and late). sub-plot...
