Title: Development of Sugarbeet Germplasm Lines Resistant to Storage Rot
Author: Bugbee, W. M.; Campbell, L. G.
Description: In North Dakota in until 1984, up to 75% of the sugar beet crops were simply stored in large exposed piles for up 10 150 days. This allows the beets to rot due to built up of pathogens In 130 days one million ponds of sucrose will be lost and the increased impurities will cause an additional loss of 1.4 million pounds of sucrose to molasses, a total loss of 2.4 million pounds of sugar from a factory processing 450,000 tons of sugar beets per year. These losses vary by year. Three forms of rot fungi had been identified as being the prime contributors of these aforementioned losse: phoma batae frank, penicillium claviforme bainier and botrytis cinereaq l. A reduction in losses can be made by minimizing beet injuries during their storage during harvest and piling. Also, reductions can made by lowering the temperature of the room they are stored in, adding ventilation to the room and eliminating debris and soil from the beets. This writing focuses itself upon the development of sugar beet lines that have genetic resistance to the three major rotting fungi listed. F1004, F1005 and F1006 are presented for discussion.
