The present study was carried out during the year 2013-14 on the screening of the selected linseed genotypes for yield performance in Sindh, Pakistan. The experiment was laid out at the experimental fields of Oilseeds Section, Agriculture Research Institute, Tandojam in a three replicated randomized complete block design. Twelve linseed genotypes (L-53, C-W-2, Shikarpur 2, P^-16-4, L-8, 11^-106, Hala 3, L^-17, Santane, Summit, L^-10 and check llsi 90) were screened for their agronomic performance and correlations amongst yield and its contributing traits were calculated. The analysis of variance suggested significant (P < 0.05) variation among linseed genotypes for all the traits studied in this experiment. Most of the genotypes attained flowering and maturity earlier than the check variety; while P^-16-4 surpassed Ilsi-90 for primary branches; and most of the remaining genotypes were at par with the commercial check for primary branches. Genotype L^-10 surpassed the commercial check for capsules plant^-1 and L-8 was at par with the commercial check; while none of the genotypes could surpass commercial check variety for seed index, but 11^-106, Hala-3 and Summit also showed promising performance regarding the seed index. All the genotypes tested in this experiment such as L-53, C-W-2, Shikarpur 2, P^-16-4, L-8, 11^-106, Hala 3, L^-17, Santane, Summit, L^-10 surpassed the commercial check variety Ilsi-90 for seed yield plot^-1. The correlation coefficient for yield and its contributing traits of linseed genotypes showed a positive and significant (P < 0.05) association for primary branches plant^-1 vs seed yield plant^-1 (r = 0.3334^*), days to maturity vs spike length (r = 0.5384^**), days to 75% flowering vs days to 90% maturity (r = 0.4073^**), days to 75% flowering vs seed index (r = 0.4291^**), days to 90% maturity vs seed index (r = 0.3973^**) and seed index v/s seed yield plot^-1 (r = 0.5160^**). Negative and significant (P < 0.05) association was observed for primary branches plant^-1 vs days to maturity (r = -0.368^*), capsules plant^-1 vs days to maturity (r = -0.3567^*), days to 90% maturity vs seed yield plant^-1 (r = -0.4156^**) and days to 90% maturity vs seed yield plot^-1 (r = -0.3423^*). The new genotypes possess the potential to become future varieties for general cultivation in Sindh province.
