Stem reserves in grain crops are considered important filling under post-anthesis stress the absence/low availability of photosynthetic assimilates. Considerable variation is present among genotypes for stem reserve translocation wheat. Therefore, this study aimed to exploit phenotypic wheat control and chemically induced conditions. The six parents their corresponding direct cross combinations...

The frequency of heat events is likely to increase due global climate change, posing an increasing risk wheat production. To optimize crop management strategies for coping with future climates, it crucial quantify the high-temperature occurrence during cropping seasons. Here, sixty-six years (1955~2020) meteorological data reproductive growth were collected from six stations in Huaibei Plain An...

ABSTRACT Current models for forecasting Fusarium head blight (FHB) and deoxynivalenol (DON) levels in wheat are based on weather near anthesis, and breeding for resistance to FHB pathogens often relies on irrigation before and shortly after anthesis to encourage disease development. The effects of post-anthesis environmental conditions on FHB are poorly understood. We performed a field experime...

in this study the effects of source limitation on grain yield of twelve barley cultivars (‘aras’,‘jonub’,‘reihan’,‘zarjou’,‘sararoud’,‘sahra’,‘fajr30’,‘karoun’,‘gorgan’,‘makouei ’and ‘nosrat(’ under post anthesis water deficiency were studied. source limitation treatments were included that control, removing of awn, leaves below flag leaf, flag leaf and spike photosynthesis. all source limitati...

The present study was carried out during rabi 2017-18 at ICAR-Indian Agricultural Research Institute, New Delhi to investigate the effect of stay-green trait on grain yield in wheat under combined heat and drought stress. Two high stay green (GCP 6 GCP 33) two low 23 30) Recombinant Inbred Lines (RILs) along with their parents (HI1500/DBW43) were grown field conditions timely sown irrigation (c...

breeding for environmental stress is one of the most important goals in plant breeding. among stresses, drought stress has high influencing on limitation of wheat production. so, in order to find the best drought tolerant genotypes, 24 genotypes were planted in three separate experiments in ardebil: one with optimum irrigation (control), another with water stress at pre-anthesis stage and the o...
