The F1 along with parents of a 4 x 6 line x tester crosses in safflower were studied and seven parameters, i.e., D 2 7 based on 7 characters and D24 based on yield and its 3 direct componenets and mid parent value (MP-Y), F1 mean (F1-Y), relative heterosis (RH-Y), biparental average GCA (MPGCA-Y) and SCA effect (SCA-Y) for yield were estimated. Twenty four selected crosses were studied for segr...

In a paper submitted previously, the author argued that a new AES evaluation criterion of future resiliency be added, defined as the ability to respond to the uncertain future and that this criterion could best be met by NIST selecting multiple disparate AES winners. This paper continues that discussion by providing more rationale. It also asks some questions and explores possible outcomes of t...

strategic selection problem is a multi-criteria problem which includes conflicting tangible and intangible criteria. in order to select the most appropriate strategic alternative it is necessary to make tradeoffs between these criteria as well as taking into account the resource limitations which may exist. available methods neglect the distance concept which exists between the alternatives wei...

Abst rac t . This paper describes a genetic learning system called SIA, which learns attributes based rules from a set of preclassified examples. Examples may be described with a variable number of attributes, which can be numeric or symbolic, and examples may belong to several classes. SIA algorithm is somewhat similar to the AQ algorithm because it takes an example as a seed and generalizes i...

The impact of chemical desiccation on yield showed contrasting results depending on seedmoisture content at the time of application. Its effects on seed deterioration are still unknownand could be modified by seed composition. Objectives were to evaluate the impact of chemicaldesiccation on: i) hybrid sunflower seed yield and composition at harvest time, ii) seeddeterioration during long-term s...

Forming limit diagrams (FLDs) are calculated based on both the Marciniak and Kuczynski (M-K)  model and the analysis proposed by Jones and Gillis (J-G). J-G analysis consisted of plastic deformation approximation by three deformation phases. These phases consisted of homogeneous deformation up to the maximum load (Phase I), deformation localization under constant load (phase II) and local necki...

in order to evaluate drought tolerance of cultivars and advanced grain sorghum lines, an experiment was conducted as split-plot on randomized complete blocks design with three replications at experimental field of seed and plant improvement institute, karaj in 2009. three levels of irrigation regimes including normal irrigation (ir0=60 mm), moderate stress (ir2=120 mm) and sever stress (ir3=180...
