response of bread wheat genotypes with different flowering habits to sowing date in isfahan

چکیده
in order to assess the impact of different sowing dates on yield and yield components of wheat genotypeswith different growth habits, a two years study (2007-2009) using a split plot in randomized completeblock design with three replications was conducted in kabootarabad agricultural research station ofisfahan. three sowing dates of 12 oct., 1 nov., and 21 nov. were main plots and 15 genotypes of wheatwere subplots. the average grain yield in three planting dates was 8495, 9156 and 6749 kg ha-1,respectively. at all planting dates, the maximum and minimum grain yield belonged to spring and wintertypes and the grain yield of winter, facultative and spring groups were 7519, 8267 and 8614 kg ha-1,respectively. at 1 nov. five spring genotypes m-81-13, bahar, pishtaz, kavir and marvdasht andfacultative cultivar alvand produced the highest grain yield by an average of 10433, 10146, 10040, 9843,9822 and 9813 kg/ha and therefore can be recommended for planting in temperate regions of theprovince. spikes per m2 and grain weight were the most important yield components that were reduced inresponse to late planting. based on the results, 1 nov. can be recommended as the best planting date forthe region.

Selection of drought tolerant wheat genotypes for Arid and Semi-arid lands (ASALS) of Kenya, which consist of 83% of total land area, can provide alternative agricultural land for expansion. To reduce cost of dryland research, simulated drought under a rain shelter offers a good alternative for screening because marginal areas are vast and widespread. Four moisture regimes which simulated termi...
