摘要
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<sup>-1</sup>6-4, L-8, 11<sup>-1</sup>06, Hala 3, L<sup>-1</sup>7, Santane, Summit, L<sup>-1</sup>0 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<sup>-1</sup>6-4 surpassed Ilsi-90 for primary branches;and most of the remaining genotypes were at par with the commercial check for primary branches. Genotype L<sup>-1</sup>0 surpassed the commercial check for capsules plant<sup>-1</sup> 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<sup>-1</sup>06, 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<sup>-1</sup>6-4, L-8, 11<sup>-1</sup>06, Hala 3, L<sup>-1</sup>7, Santane, Summit, L<sup>-1</sup>0 surpassed the commercial check variety Ilsi-90 for seed yield plot<sup>-1</sup>. 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<sup>-1</sup> vs seed yield plant<sup>-1</sup> (r = 0.3334<sup>*</sup>), days to maturity vs spike length (r = 0.5384<sup>**</sup>), days to 75% flowering vs days to 90% maturity (r = 0.4073<sup>**</sup>), days to 75% flowering vs seed index (r = 0.4291<sup>**</sup>), days to 90% maturity vs seed in
