'Plant Breeding: Sustaining the Future' Abstracts of the XVIth EUCARPIA Congress, Edinburgh, Scotland, 10-14 September 2001 GRAIN QUALITY OF BARLEY FOR BREWERY IN KAZAKHSTAN A.I. ABUGALIEVA Kazakh Research Institute of Agriculture, Yerlepesov str. 37, Almalybak, 483133, Almaty reg, Kazakhstan

Grain of barley cultivars (cvs) growing in Kazakhstan and 36 accessions from competitive trials was studied to reveal the most perspective cvs for brewery. It has been analyzed the contents of protein and fractions, contents of starch, amylose, extractivity, hullness, determined by NIR-spectroscopy (Pacific Scientific 4250). The high extractivity level was positively related to the highest albumin+globulin proportion (35-46%) to total protein and less proportion of hordein: 15-28% in Arna; 16-29% - Odessky 100; 18-33% - Donetsky 8; 16-33% - Karabalyksky 150. The analysis of Kazakhstan barley cultivars germplasm has allowed to reveal commercial barley cultivars adequate to requirements for malting barley (the contents of protein <12%, starch >60%; extractivity >78%; hullness <9%): Arna, Karabalyksky 150, Tselinnyi 91, Donetsky 8; Odessky 100, and new perspective winter cultivars.
