ABSTRACT: 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 -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 -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 -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.
