Physio-morphological analysis of rapeseed-mustardcultivars

MANZER HUSSAIN SIDDIQUI ; MOHAMMAD Firoz

Seven cultivars of rapeseed-mustard, viz. IGC-01 and Pusa Gaurav of Brassica carinata, Jagannath, Kranti, Rohini and TERI (0E) M21-Swarna of Brassica juncea and Hyola PAC-401 of Brassica napus, were evaluated in a randomized complete block design field experiment. Shoot length per plant, leaf number per plant, leaf area index, fresh weight per plant, dry weight per plant and net assimilation rate were studied at 45 and 60 days after sowing to assess their growth performance. Carbonic anhydrase activity, nitrate reductase activity and leaf NPK content were estimated at above stages. At maturity, pod number per plant, seed number per pod, 1000-seed weight, seed yield, oil percentage and oil yield as well as fatty acid composition of oil were estimated. The data revealed the overall superiority of Hyola PAC-401, which produced highest yield of seed and oil. It was followed by TERI (0E) M21-Swarna, which showed parity with Rohini. In comparison, Kranti performed poorly. It was also confirmed that the oil of Hyola PAC-401 and TERI (OE) M21-Swarna, was almost free from erucic acid and could, be preferred for human consumption.
