Boundary effects in the Marschak-Machina triangle

This paper presents the results of a study that sheds new light on the shape of indifference curves in the Marschak-Machina triangle.The most important observation, obtained non-parametrically, concerns jumps in indifference curves at the triangle legs towards the triangle origin.These jumps, however, do not appear at the hypotenuse.The pattern obs

Development and characterization of a Psathyrostachys huashanica Keng 7Ns chromosome addition line with leaf rust resistance.

The aim of this study was to characterize a Triticum aestivum-Psathyrostachys huashanica Keng (2n = 2x = 14, NsNs) disomic addition line 2-1-6-3.Individual line 2-1-6-3 plants were analyzed using cytological, genomic in situ hybridization (GISH), EST-SSR, and EST-STS techniques.The alien addition line 2-1-6-3 was shown to have two P.huashanica chro
