Description Two field experiments were carried out with ten genotypes viz., TMV-2, R-8808, Dh-
3-30, JL-24, GPBD-4, TAG-24, Dh-86, TGLPS-3, Mutant-III and Dh-40 to understand the
effect of seed source on field performance and seed quality during kharif 2006 and effect of
growing season on seed yield and quality during kharif 2006 and rabi/summer 2007 at
Oilseeds Scheme, Main Agricultural Research Station, Dharwad. Between two seed sources
the rabi/summer seed source though exhibited higher growth parameters viz., number of
primary and secondary branches (6.79 and 2.15), length of primary and secondary branches
(31.22 and 12.95 cm), the yield components and pod yield/ha were higher in kharif seed
source (3302 kg/ha), because of better field emergence and plant population per plot (212.2)
which was due to its higher initial seed quality viz., germination (74.8%), root length (16.75
cm), shoot length (5.39 cm) and electrical conductivity (0.293 dS/m).
The second experiment was carried to understand the seasonal influence kharif season
was found to be better for crop growth like, primary and secondary branches per plant (6.79
and 1.84) and length of primary and secondary branches (29.49 and 12.86 cm), yield and seed
quality parameters as compared to rabi/summer, but yield parameters like, number of
developed pods per plant (10.80), yield per plant (11.56 g) and yield (3376 kg/ha) were
recorded highest in rabi/summer season. Among ten genotypes studied, GPBD-4 (3671
kg/ha) and Mutant-III (3641 kg/ha) in kharif and Dh-86 (3899 kg/ha) and TAG-24 (3798
kg/ha) in rabi/summer were found to be better for field performance.
The kharif harvested seeds showed higher initial dormancy than rabi/summer.
However, the complete dormancy was broken on seventh week after harvest recording
maximum germination of 99 per cent in both the seasons.
