Twenty-two lines were crossed with 2 testers in a Line × Tester mating design 2017-18 and the resulting 44 crosses along lines, three checks i.e., BARI Hybrid Maize 9 (BHM 9), 981 Elite evaluated alpha lattice two replications, during rabi, 2018-19. Highly significant differences found among genotypes for all characters studied. Parent parents vs except ASI indicating greater diversity parental...

The experiment was conducted to evaluate the effect of defoliation on grain and fodder yield maize at research field laboratory Crop Physiology Ecology Department, Hajee Mohammad Danesh Science Technology University, Dinajpur during period December 2018 June 2019. trial carried out in a randomized completely block design with three replications. experimental treatments were: T1– Control (withou...

Drought stress is the principal cause of production losses in maize (Zea mays L.), especially a rainfed ecosystem. Reducing yield penalty under conditions demands development hybrids with improved tolerance to drought stress. The extent genetic variability and association among traits over irrigated water of  72 were studied. analysis variation reveaeds that significant was observed condit...

Global warming has resulted in increasingly frequent and severe drought and/or precipitation events. Severe drought limits crop water availability and impacts agricultural productivity and socioeconomic development. To quantify drought-induced yield loss during the main crop stages in Liaoning province, China, aspects of drought episodes (magnitude, duration, and frequency) were investigated du...

Maize crops grown during summer-rainy season in Asian tropics are prone to face both drought and excess moisture stress due uneven distribution patterns of monsoon rains in the region. We attempted to identify the relationship between drought and excess moisture tolerance through evaluation of a set of elite maize inbred lines, including lines with known performance under drought, excess moistu...

Flowering time is an important factor determining yield and seed quality in maize. A change in flowering time is a strategy used to survive abiotic stresses. Among abiotic stresses, drought can increase anthesis-silking intervals (ASI), resulting in negative effects on maize yield. We have analyzed the correlation between flowering time and drought stress using RNA-seq and bioinformatics tools....

Leaf growth and Anthesis-Silking Interval (ASI) are the main determinants of source and sink strengths of maize via their relations with light interception and yield, respectively. They depend on the abilities of leaves and silks to expand under fluctuating environmental conditions, so the possibility is raised that they may have a partly common genetic determinism. This possibility was tested ...

In the past century, climate change has become more significant, which a great impact on crop growth, especially food security. Based regional model PRECIS, high-precision grid data in China under RCP4.5 and RCP8.5 scenarios were output, amplification calibration of DSSAT calibrated verified combination with maize planting from 2005 to 2015, including observation agrometeorological stations, ec...
