Early selection for drought tolerance in popcorn based on gene effects estimated in seedlings

چکیده
Low rainfall rates are becoming increasingly frequent because of climate change, causing droughts and threatening world food security. For popcorn, drought is the most limiting abiotic factor for plant’s growth development. Thus, water deficit directly impacts crop productivity. Based on knowledge genetic basis traits involved in stages popcorn germination seedling development under stress, genotypes with potential adaptation to adverse growing conditions can be selected early. Therefore, data effects combining ability 10 parents were compiled propose breeding strategies cultivars greater stress early stages. Forty-five diallel hybrids evaluated two different regimes, that is, full irrigation. This corresponded a retention capacity 25% 70% paper. The plants watered daily as needed seven days. A range factors evaluated, including speed index seventh day; shoot length dry weight; root system length, weight, root-to-shoot ratio, maximum number, network area, specific volume. Breeding adaption successful when used, dominance (ϕ s ). These control at stage. combinations L61 x P2 L71 P3 recommended, view more performance estimated related system.

Evaluation of Drought Tolerance Indices for Selection of Superior Genotypes in Black Cumin (Nigella sativa L.)
Drought stress is considered as one of the most important constraints to the crop production, including medicinal plants in many arid and semi-arid regions. This study was carried out to determine the most effective indices for drought tolerance and identification of tolerance genotypes under drought conditions in N. sativa. For this purpose, 36 genotypes of N. sativa were tested as a split plo...

One of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. In order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...
