Description ABSTRACT
The present investigation “Effect of varying environment on morpho- physiological attributes and seed quality of Niger [Guizotia abyssinica (L.f.) Cass.]” under taken at Research Farm of Project Coordinating Unit of Sesame and Niger, (ICAR), JNKVV, Jabalpur (M.P.) during the kharif season of 2012-2013. The treatment combination composes of six varieties and four date of sowing in split plot design replicated thrice. Various treatment of varieties and dates of sowing influenced showed marked imperiently in physiological biochemical estimation, and morphological yield attributing components of growth and productivity of niger. and varieties comprised of six niger varieties Viz., JNC-1, JNS-9, Utkal Niger-150, Birsa Niger-2, IGP-76, and GA-10 which were assessed for various morpho-physiological traits and productivity potential

The results revealed that among phenological traits indicated that Birsa Niger-2 had the earliest bud initiation (38.25 days), flower initiation (44.58 days) and days to 50 % flowering (56.25 days), however Birsa Niger-2 was found to be associated with longer reproductive phase (72.33 days). Birsa Niger-2 (93.66 days) attained the physiological maturity at the earliest. These traits may be utilized in a breeding programme. JNS-9 LAI (2.42), LAD (36.42 cm2days), Birsa Niger-2 CGR (4.97 g/cm2/day), JNC-1 RGR (0.026 g/g/day) SLA (4.97 cm2/g). JNS-9 quantum efficiency (0.035), JNS-9 water use efficiency (6.94 µmol/mmol) and JNS-9 mesophyll efficiency (1409.76 µmol/mmol), JNC-1 photosynthetic rate (34.76 µmol/m2/s), Utkal Niger-150 carboxylation efficiency (0.177 mmol/m2/s -1(m molmol -1) -1 Utkal Niger-150 chlorophyll index (21.40 g/m2) and Birsa Niger-2 transpiration rate (7.042 mmol/m2/s) may be utilized in a breeding programme for mentioned traits.
Resulted in a higher magnitudes of plant height (98.68 cm), number of capitule/plant (34.83), number of seeds/capitule (28.00), effective nodes/plant (cm) (67.62 cm) and number of nodes/plant (8.42) which in turn had reflected in highest grain yield (481.33 kg/ha). The result revealed that higher magnitudes of growing degree days (875.82 days), flower initiation (907.04 days) and days to 50 % flowering (1139.12 days), however Birsa Niger-2 was found to be associated with longer reproductive phase (1421.25 days). Birsa Niger-2 (1724.70 days) attained the physiological maturity at the earliest. heliothermal unit (6303.47days), flower initiation (8123.01days) and days to 50 % flowering (8674.16 days), however Birsa Niger-2 was found to be associated with longer reproductive phase (11342.51 days). Birsa Niger-2 (14487.55 days) attained the physiological maturity at the earliest. and phenothermal unit in (8763.51 days), flower initiation (9691.59 days) and days to 50 % flowering (90557.17 days), however Birsa Niger-2 was found to be associated with longer reproductive phase (14871.44 days). Birsa Niger-2 (18089.99 days) attained the physiological maturity at the earliest. JNC-1 was ranked second in yield performance in resultant of comparatively higher magnitudes of physiological parameters. Protein (%) (9.12) and oil % (40.22), JNC-1 seed fat yield kg/ha (194.35), Utkal Niger-150 fibre % (15.22), and Birsa Niger-2 ash %(4.61).
