DNA marker plays important role as valuable tools to increase crop productivity by finding plausible answers to genetic variations and linking the Quantitative Trait Loci (QTL) of beneficial trait. Prior approaches in development of Short Tandem Repeats (STR) markers were time consuming and inefficient. Recent methods invoking the development of STR markers using whole genomic or transcriptomic...
in order to study the possibility of control of heterodera schachtii in sugarbeet fields through integration of rotation with non- host crops and resistant catch crops and their effects on quantitative and qualitative traits of sugarbeet, this study was started from 2002 for three years in esfahan province. the experiments were carried out in a randomized complete block design with eight treat...
For maximum sucrose production by sugarbeets (Beta vulgaris L.) in southern Idaho, the available soil nitrogen (N) level should be highest during early July, when the plant N uptake (N u p) rate is highest, and lowest by the latter part of August ( 1, 12r. Inadequate N during the early growth stages limits root and sucrose yield, whereas excess N stimulates top growth, increases root impurities...
Trisomic and diploid hybrids of sugarbeet (Beta vulgaris L.) X wild beet (B. procumbens Chr. Sin.) inherited the gene for resistance to Heterodera schachtii Schm. from B. procumbens. The hybrids showed partial resistance to H. schachtii, manifested in failure of larvae to reach maturity. Although significantly greater numbers of female nematodes developed on plants inoculated with populations f...
Cysts of Heterodera schachtii were treated in a water bath at constant temperatures ranging from 45 - 62.5 C for 1 sec to 28 hr. Treated and untreated cysts were incubated 8 weeks in sugarbeet root diffusate at 24 C to measure emergence of surviving larvae. Within the temperature range of 49 - 54 C, the minimum lethal temperature was proportional to the log time of treatment. No larvae emerged ...
