Six lines and five testers were crossed in line x tester fashion and the F1s were evaluated under coastal saline situation. The ratio between the estimates of additive and dominance variances indicated preponderance of nonadditive gene action for the characters namely, plant height, number of productive tillers, boot leaf length, panicle length, grain weight per primary panicle and grain yield ...

in order to study the effect of supplementary irrigation and different plant densities on grain yield and yield components of chickpea cv hashem, an experiment was conducted as split plot arrangement in a randomized complete block design with three replications in sirvan, ilam during 2008-2009 cropping season. main plot included supplementary irrigation (check as non-irrigation, supplementary i...

in order to investigate the effects of drought stress on grain yield and its components, a study was carried out (2011) as split plots in randomized complete blocks design in isfahan (32° 40'  n,51° 48' e). main factor was drought stress in four levels including irrigation after 80, 100, 120, and 140 mm evaporation from evaporation pan (class a) and subplots were three cultivars (sirena, record...

Combining ability along with heterosis was elucidated in the 21 F1 hybrid population of rice derived from a 7 × diallel mating design. Furthermore, to formulate strategy for marker-based prediction heterosis, molecular genetic diversity (GD) then surveyed among seven parental lines RAPD markers. Analysis combining revealed significant GCA and SCA variances ratio between aforesaid parameter more...

Before selecting genotypes for nutritional quality characters (protein, oil and micronutrients content) and anti-nutritional factor (phytic acid), it is important to know how much selection is likely to affect yield. Using a diverse range of genotypes, relationships between quality traits with yield and yield attributes in pearl millet were investigated. The number of productive tillers, panicl...

Whether to develop inbred cultivars or F1 hybrids is a dilemma faced by many rice (Oryza sativa L.) breeders. This could be partially answered if one could select superior recombinant inbred lines with an equal yielding ability and good quality traits from commercial F1 hybrids. Thus, it was attempted in this study to select superior inbred lines from 2 commercial F1 hybrids after application o...

to determine the correlation between grain yield and its components in some grain corn hybrids and their cause and effect relationships in various fertilizer application methods, an experiment was carried out as split plot based on randomized complete block design with two fertilizer application methods (urea foliar application and soil application method), four grain corn hybrids (ns 640, kons...

The erect panicle model super-rice can rationally transform the solar energy into accumulated organic matter (biomass) and increase grain yield. The phenotype of erect panicle architecture controlled by DENSE AND ERECT PANICLE 1 (DEP1) has been used in rice breeding for nearly a century owing to its high-yield, lodging tolerance with strong stem, reasonable population structure and high nitroge...
