Abstract

Abstract

The purpose of this investigation was to determine if a systematic program of inbreeding and selection is a practical method of breeding colonial bentgrass, Agrostis tenuis Sibth. Inbreeding effects were investigated in 95 parental selections having open-pollinated origins in Oregon and in 277 first inbred generation progenies. Self- and open-pollinated seed-setting, self-fertility, pollen quality and the creeping habit of growth were studied.

The results of this experiment indicate that it is possible to obtain highly vigorous second generation inbred plants. Inbreeding and selection within inbred lines is a practical method for breeding colonial bentgrass. Most plants were observed to spread by means of determinate stolons which originated as determinate rhizomes.
