Summary:<span style="font-family: Times New Roman; font-size: small;"> </span><p style="margin: 0in 0in 10pt;" class="MsoNormal"><span style="color: #211d1e; line-height: 115%; font-size: 10pt;"><span style="font-family: Calibri;">Character association and path analysis were performed for black seed cultivars using a split-plots design based on RCBD with three replications. Three cultivars (‘Varzaneh’, ‘Semirom’ and ‘Mobarakeh’) were studied under three levels of irrigation (normal irrigation, irrigation with drought stress before and after flowering). Under normal and abnormal irrigations the relation of seed yield and three characters biological yield, number of capsule per plant and thousand seed weight were high, positive significantly (<span style="mso-bidi-font-style: italic;">p</span></span></span><span style="color: #211d1e; line-height: 115%; font-family: &quot;Garamond Premr Pro&quot;,&quot;serif&quot;; font-size: 10pt; mso-bidi-font-family: &quot;Garamond Premr Pro&quot;; mso-bidi-font-style: italic;">≤</span><span style="color: #211d1e; line-height: 115%; font-size: 10pt;"><span style="font-family: Calibri;">0.01); the relation between yield and number of sub branch was positive significantly (<span style="mso-bidi-font-style: italic;">p</span></span></span><span style="color: #211d1e; line-height: 115%; font-family: &quot;Garamond Premr Pro&quot;,&quot;serif&quot;; font-size: 10pt; mso-bidi-font-family: &quot;Garamond Premr Pro&quot;; mso-bidi-font-style: italic;">≤</span><span style="color: #211d1e; line-height: 115%; font-size: 10pt;"><span style="font-family: Calibri;">0.05). In terms of abnormal irrigation there was a positive significant correlation between essence percent and yield (<span style="mso-bidi-font-style: italic;">p</span></span></span><span style="color: #211d1e; line-height: 115%; font-family: &quot;Garamond Premr Pro&quot;,&quot;serif&quot;; font-size: 10pt; mso-bidi-font-family: &quot;Garamond Premr Pro&quot;; mso-bidi-font-style: italic;">≤</span><span style="font-family: Calibri;"><span style="color: #211d1e; line-height: 115%; font-size: 10pt;">0.05). Under normal irrigation the most direct effect of traits on yield was obtained from biological yield (0.778) followed the number of capsules per plant (0.245). The most indirect effect of traits on yield was obtained from biological yield through thousand seed weight (0.576) followed stem diameter through biological yield (0.468). Under water deficiency conditions the most direct effect of traits on yield was obtained from biological yield (0.811) followed the number of capsules per plant (0.231). The most indirect effect of traits on yield was obtained from biological yield through thousand seed weight (0.562).</span></span></p><span style="font-family: Times New Roman; font-size: small;"> </span>
