| Abstract: |
Field cum laboratory analysis were carried out in the Department of Vegetable Crops,
Punjab Agricultural University,· Ludhiana, during 2003-04 to evaluate effect of parental row
ratios (1:1, 2:1 and 3:1of female:male) and foliar sprays (GA3 10 and 20 ppm and urea
1and 1.5 %) on hybrid seed yield and quality of chilli obtained by using male sterile line
(MS-12). The experiment was laid out in split plot design with three replications in an
isolated plot. The experiment comprised of 15 treatments with the combination of three
parental row ratios as main plot treatments and five foliar sprays as sub-plot treatments.
Laboratory analysis for testing seed quality was done after sufficient time to break seed
dormancy. The findings revealed that the alternate row of male (S-2530) with MS-12
recorded the highest fruit set (27.33 %), fruit yield (48.80 g) per plant and seed yield (2.75
g) per plant. Nevertheless, two rows of female planted with single row of male gave
maximum seed yield per unit area (60.40 kg ha-1
) · while the quality remained at par. All the
foliar treatments significantly influenced plant height, number of fruits per plant, seed yield,
germination percentage and seed vigour over control. Foliar spray of GA3 20 ppm recorded
maximum fruit yield (49.25 g) per plant with the minimum seed yield of 45 kg ha·1
• The
highest seed yield (2.95 g) per plant and seed yield per unit area (70.16 kg ha-1
) was
recorded with the foliar spray of 1% urea. Foliar application of 1% urea_ was also effective in
significantly improving seed germination and seed vigour. Hence, it may be concluded that
maximum hybrid seed yield (89.38 kg ha-1
) of CH-3 can be produced by planting at 2:1 row
ratio of female:male parent followed by foliar spray of urea 1% at 30 and 40 days after
transplanting. |
