ﺗﻬﻴﻪ ﻫﻴﺒﺮﻳﺪ دﻳﭙﻠﻮﺋﻴﺪ ﺑﺎ ﻓﺮم رﻳﺸﻪ ﺻﺎف و ﮔﺮد (Broad elliptic) در ﭼﻐﻨﺪرقند

The end of the roots of sugar beet is broken at the harvest time due to its conical shape which causes considerable losses of root and also sugar yield. Meanwhile, due to lateral grooves on the roots, the field soil is transferred to the factory considerably. In the regions where soil is infected by nematode or Rhizomania, transferring the soil leads to disease expansion. In this study, new hybrids of full-sib families related to three breeding populations coded 27102and 27131 with round and smooth roots were evaluated in Karaj and Moghan regions. Hybrids in Karaj and Moghan experiment, a randomized complete block design with 4 replications were grown in the 2011 crop year. According to the results of Karaj region, and the Moghan were identified in terms of quantity, quality and appearance of hybridsThe best hybrids were identified as (261 * 231) * 27102-S1.25, (261 * 231) * 27102-S1.20. Therefore, the selection of hybrids in pollination and breeding family and uniform quality provision and could be used in breeding programs. . However, at present, the number of hybrids in comparison with resistant varieties of favorable conditions. Cluster analysis based on the average performance and quality characteristics of hybrids divided into five groups.
