Abstract:
... The selection response of wheat (Triticum aestivum L.) under water-limited condition can be enhanced through breeding novel genotypes possessing drought-adaptive and yield-related agronomic and physiological traits. The objective of this study was to evaluate terminal drought tolerance among bread wheat genotypes and select superior parents for breeding. Agronomic and physiological responses of 28 ...

Subject:
climate change; climate models; disease outbreaks; disease severity; leaf rust; meteorological data; prediction; probability; temperature; triticale; Poland
Abstract:
... Disease development in plants is strongly dependent on weather conditions, with temperature playing a particularly significant role by influencing latency period duration. Using two models describing the relationship between latency period and temperature, we performed simulations aimed at predicting changes in the latency period of leaf rust (Puccina recondita f. sp. tritici) on triticale in resp ...

Subject:
agronomic traits; backcrossing; flowering; fruit yield; fruits; genes; genotype; heat tolerance; microsatellite repeats; parents; phenotype; plant height; temperature; Malaysia
Abstract:
... Domestic production of chilli in Malaysia is insufficient which accounted for 52% self-sufficiency level. Poor performance of local varieties under high temperatures above 42°C is one of the major factors affecting chilli production. This study was conducted with the objective of introgress heat-tolerant gene (Hsps) from AVPP0702 donor into Kulai using marker-assisted backcrossing. A total of 68 S ...

Subject:
Triticum aestivum; analysis of variance; canopy; drought; drought tolerance; genotype; grain yield; greenhouses; heading; plant breeding; plant height; screening; spikelets; temperature; water stress; wheat; yield components
Abstract:
... Wheat genotypes with pre- and post-anthesis drought tolerance offer enhanced yield gains under water-limited environments. This study determined pre- and post-anthesis drought responses of selected bread wheat genotypes in order to identify and select candidate genotypes for breeding. Fifteen genetically differentiated wheat genotypes were evaluated under non-stressed (NS), pre-anthesis drought st ...
