The results showed as follows:Vdrgl has 501bp contained NBS-LRR conservative motifs, it seems like the NBS-LRR type resistance protein gene and locates on acme of Linkage Group D02, 5.6cM apart from marker pAR286E4C and Unig22D03bE6D.

• 利用PimaS6与Acala Maxxa杂交的四倍体棉花海陆杂交群体对12个Vctrg序列进行了棉花基因组定位。 定位结果表明：Vdrg1定位于D02连锁群端点，与标记pAR286E4C和Unig22D03bE6D相距5.；6cM；
