Abstract

Inbreeding effect on seed yield was studied in 150 S1 lines derived from 30 genetic stocks of isabgol. Open pollinated genotypes manifested higher seed yield than their most of the S1 lines studies. Maximum (47.78%) and minimum (1.00%) inbreeding depression was recorded by the S1 line of genotypes HI-9 and MIB-124, respectively. The S1 line of the genotypes MIB 123, RI 158, J 16, PB 62, RI 130, RI 157 and DM 11 exhibited higher seed yield and least inbreeding depression suggested the preponderance of additive gene action and as such disease cultivars could be improved by selection.
