水稻의 濃綠葉色과 Dripping Wet 形質의 連鎖分析

Linkage Analysis of Dark Green Leaf Color and Dripping Wet Character in Rice

A dripping wet character was found in some F₂ families of the cross Suwon224× Malagkit Sinaguing, where the parental varieties were all normal. This dripping wet line(wx139) was crossed to the genetic stock H106 which had dark green leaf color liguleless and narrow leaf character. The dripping wet character of wx139 and the dark green leaf color of H106 appeared to be controlled by a single recessive gene, drp and dg, respectively. Linkage relations were found between dg and drp, dg and lg (liguleless) and dg and nal (narrow leaf) with the recombination values of 8.6, 7.3 and 6. 0% respectively. These genes arranged in the order of nal-dg-lg-drp.
