Methodology for selection index updating was developed to allow multistage selection. The program determines truncation points for each stage of selection that will maximize either profit or the ratio of aggregate economic gain to cost (R = delta H/C). Either maximum profit or R may be attained by reducing the cost of performance testing in later stages of a multistage program. In order to elim...

An exact transformed culling method for any number of traits or stages of selection with explicit solution for multistage selection is described in this paper. This procedure does not need numerical integration and is suitable for obtaining either desired genetic gains for a variable proportion selected or optimum aggregate breeding value for a fixed total proportion selected. The procedure has...

ABSTRACT Several traits must be simultaneously considered in selection of tobacco cultivars for meeting the requirements farmers, manufacturers and consumers. Breeders should have an understanding associations between economically-important order to devise best strategy response all them. Utilization indices has been shown one most efficient selecting correlated characters. In tobacco, no repor...

Simultaneous selection for various agronomic traits, cooking time and mineral concentration are major challenges common-bean (Phaseolus vulgaris L.) breeding programs. The authors of this study proposed to analyze genetic gain estimates obtained by direct indirect using indices economic weights 13 determine the most efficient strategy simultaneous fast cooking, mineral-biofortified common bean ...

New theory on measuring gain and index changes in femtosecond pump probe studies suggests a spectral artifact is present which may have obscured the ultrafast response in previous studies of InGaAsP laser diode amplifiers. A femtosecond heterodyne pump-probe technique is implemented using an Erbium-doped stretched-pulse modelocked fiber laser centered at 1.55 gm and used to obtain simultaneous ...

This article presents a high gain patch antenna with negative refractive index (NRI) superstrate for the application of Radio frequency energy harvesting system. Triangular split ring resonators (TSRR)-strip line are used as a NRI superstrate to enhance the gain of the patch antenna. It is demonstrated that the proposed triangular split ring resonator (TSRR) structure metamaterial yields negati...
