in order to evaluate and drought tolerance selection in cowpea genotypes and to identify the best indices for drought tolerance, an experiment was conducted at research field university of tehran in karaj during 2011-2012 growing season. in this study, 31 cowpea genotypes were evaluated in a randomized complete block design (rcbd) with three replications under normal irrigation (non- stress) an...

This investigation was carried out for genetic characterization and determination of drought tolerance ten Egyptian cultivars wheat (Triticum aestivum L.), namely Misr 1, 2, Gemmiza 9, 10, 11, 12, Shandawel Giza 168, 171, Sids 14. These were grown in two winter seasons: 2018/2019 2019/2020 at the experimental farm Fac. Agric., Suez Canal Univ., Ismailia, Egypt, under watering regimes: normal (1...

continual heat stress affects approximately 7 million hectares of wheat in developing countries, while terminal heat stress is a problem in 40% of temperate environments, which cover 36 million hectares throughout the world. heat tolerance is a quantitative and complex trait that doesn’t have much success in direct selection. for this purpose, however, a thorough understanding of physiological ...

Rice (Oryza sativa L.) is one of the most important cereal crops in the world. India is one of the largest rice-producing countries. Although more than 900 rice varieties have been released in India, many of them are no longer cultivated within a few years of release due to inconsistent performance in diverse environments; only a few varieties with stable performance continue to be under cultiv...

decreasing irrigation via partial root zoon drying (prd) save water and decreased production expenses. for comparing common irrigation and prd on tomato cv. falcato an experiment was designed in massey university of new zealand. treatments were control (irrigation in a field capacity in each irrigation to whole root zoon) and prd (irrigation in a half of field capacity in each irrigation to one...
