Hamdi Sugar Beet Seed Institute – Iran Journal Article 2002 09 06 In order to determination of optimum quantity of seed pelleting materials due to sugar beet monogerm seed size. This study was carried out in seed technology department during 1997-1998. Monogerm cultiver 9597 seed lot (300kg) was firstly graded by 7 round sieves and then 7 rectangle sieves graded each bound. Some factors such as germination , monogermity and proportionate seed pelleting materials due to seed size evaluated of categories seven bounds contained 70% of total weight which had hormal seedling carsteristies. All categories nacked seed lots were coated with 1/1, 1/2 and 1/3 ratio of seed weighty pelleting materials composition, respectively. Germination, monogermity and uniformity and some other factors were determined on pelleted seeds. Results showed that the over using seed pelleting material (1/3) had negative effect on germination and uniformity. This results indicated that tooptaind acceptable germination and uniformity in emergence the proportion of seed pelleting material and seed weight should be 1/1 respectively. The results indicated suitable germination and uniformity in emergence created by 1/1 ratio of seed pelleting material and seed weight.

Okhovat Tehran Univ., College of Agriculture, Iran Journal Article 2002 09 06 In order to study the effect of beet mosaic virus on sugarbeet seed yield, an isolate of beet mosaic virus was collected from sugarbeet fields in Karaj and biologically was purified by inoculation on Chenopodium amaranticolor and propagated on Beta vulgaris cv. Cicla under greenhouse conditions. The infected sap was inoculated on leaves of sugar beet 7233 variety at two stages, after and before vernalization using a randomized complete design. with 3 treatments and 4 replication. The results showed that infection of plants before vernalization had a serious losses on seed yield. Seed production was decreased 43% as compared with healthy plants (Checks) and showed significant differences with the control. Also, stem length of the infected plants were 33.2% shorter than healthy plants as significant differences with the control. Infection of the plants after vernalization had no significant differences with the control and yield losses were about 7%.

Ebrahimi Koulaei Agriculture Research Center of Hamedan Journal Article 2002 09 06 Short growing season in cold regions is an important factor in not achieving a maximum root yield in sugar beet crop. In an investigation on possible ways to limit the effect of short season culture on the crop, six harvest dates and three sugar beet varieties were considered. The experiment was conducted as a factorial with randomized complete block design in three replications, from 1996-1998 at Ekbatan Research station in Hamedan. Planting dates (The beginning of May) and all cultural practices were kept identical for all treatments. Sugar beet harvest was carried out at selected dates, and data were collected for statistical analysis. Results of ANOVA showed that there were significant differences among sugar beet lines, with BR1 showing the highest: root yield, sugar content and white sugar yield as companed to two other lines. Significant differences were observed for root yield, raw sugar yield, white sugar yield, sugar content, the coefficient of extraction and profit gained in different harvest dates. The two dates of Oct. 12 and Nov. 11, were superior to Sept. 23 and Oct. 2 in all parameters. The highest raw sugar and white sugar content were obtained in Nov. 11 harvest date as compared to others. The highest sugar yield and white sugar yield with 10.09 t/ha and 8.7 t/ha respectively belonged to the harvest of No. 11, which excepted for the No. 1, differed significantly with other harvest dates, coefficient of sugar extraction was increased for the late harvest and the three late harvests, were superior to the early ones regarding average profit obtained in three years and that of the year 2000. Harvest dates of Nov. 11, Nov 1, Nov. 21, Oct 12 and Oct. 2 were respectively 46, 39, 33, 26 and 17% higher as compared to profit of the Sept. 23 harvest date.

Jafarpoor Department of Plant Pathology, Collage of Agriculture, University of Mashhad, Iran Journal Article 2002 09 06 This study was carried out to identify Fusarium species associated with sugar beet root rot and yellows. Pathogenicity of Fusarium oxysporum, the causal agent of Fusariumyellows of sugar beet was also investigated. Samples of infected roots were collected from fields in major sugar beet producing areas in Khorasan province during 1999-2000. Infected roots were washed, surface sterilised and plated on PDA. One hundred sixty eight isolates of Fusarium spp. were recovered. Seven species were identified including Fusarium solani (42 isolates), F. oxysporum (31 isolates), F. acuminatum (27 isolates), F. avenaceum (23 isolates), F. moniliforme (19 isolates), F. equiseti (16 isolates) and F. culmorum (10 isolates). All isolates of F. oxysporum were tested for their pathogenicity on seedlings and matured sugar beet plants. The results showed that 12 isolates (38.7%) of F. oxysporum were non-pathogenic, and 19 isolates (61.3%) were pathogenic.

The results indicated that pre-penetration stages had no importance in resistance because there was no significant difference between resistant and susceptible genotypes, but in endophytic phase some penetrating germ tubes in resistant genotype stopped in initial stages and did not develop to necrotic phase.
