| Description |
The present experimentation was carried out on ten wheat genotypes namely WH-147, Raj-4083, WH-1021, WH-1022, WH-1025, LOK-1, NW-2030, C-306, PBW-343 and PBW-550 with three level of phosphorus i.e. 20%, 50% and 100% in order to identify the genotypes efficient in phosphrous uptake and utilization, the effect of phosphrous doses on quality parameters of wheat grains and the root morpho-physiological traits associated with efficient phosphors uptake. The investigation involved pot studies under screen house conditions during the year 2008-09.Data was recorded for dry weight of root,stem and leaves,physiological parameters(Chlorophyll fluorescence, Assimilation rate, Transpiration rate, Stomatal conductance, Water use efficiency ),days to heading, days to Anthesis, days to Maturity, Grain Filling duration, Plant Height, No. of productive tillers/plant, biomass/plant, Spike length, Grain yield/plant Test weight, Phosphorus cont Quality parameter in grain . In this study day to heading, anthesis, maturity and grain filling duration got delayed at low P level (20%) as compared to 100% P. Raj-4083, WH-1022, NW-2030, WH-1025, C-306, PBW-343 and PBW-550 showed significant difference for root, shoot and leaf dry weight at different level of phosphorus during anthesis stage. WH-147 and Raj-4083 was better in maintaining WUE at different P level. Acid and alkaline phosphate activity increased with decrease in the P. Activity of both enzymes was highest in NW-2030. For majority of the yield components the genotypes Raj-4083, WH-147, LOK-1, NW-2030 and PBW-550 performed better at different P levels. Among all these seedling characteristics root length root/ shoot dry weight and no. of secondary lateral roots increased at 20% P, but shoot length decreased at 20% P. No. of secondary lateral roots was found as major determinant of P deficiency. |
