maize improvement for high temperature tolerance requires the reliable assessment of parental inbred lines and their combinations. fifteen maize inbred lines were evaluated during 2007 and 2008 in shushtar city (khuzestan province). the inbred lines were planted at two dates: 6 july, to coincide heat stress with pollination time; and 27 july, as normal planting to avoid high temperature during ...

in order to evaluate of drought tolerance in different canola varieties based on stress evaluation indices in terminal growth duration, an experiment was conducted as split-plot design on randomized complete block design with four replications at experimental field of seed and plant improvement institute, karaj in 2005 and 2006. results using stress susceptibility index (ssi) and tolerance inde...

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...

The main objective of this research was to evaluate fourteen oat (Avena sativa L.) landraces and cultivars for drought tolerance using several indices. The trials were conducted both under rain-fed and irrigated conditions for three growing seasons (2001–2004) in two locations in the Central Anatolian Region of Turkey. Biplot analysis based on the Spearman’s rank correlation matrix revealed tha...

drought stress is considered as the most important environmental abiotic stress, affecting grain yield of crop plants especially in arid and semi arid regions. increasing and utilization of the genetic diversity can be a useful strategy in breeding for drought resistance. in this study, twenty iranian durum wheat landraces along with two check cultivars were evaluated in a randomized complete b...
