INTRODUCTION:

Department of Plant Physiology at RARS, Maruteru works in rice based cropping system of Godavari Zone on the following aspects:

  • Evaluation of rice varieties for seed dormancy and to suggest strongly dormant varieties for the wet monsoon season.
  • Characterization of rice varieties under irrigated ecosystem for identification of efficient plant types and hybrid rice.
  • Characterization of rice varieties for their thermo and photo sensitivity
  • Studies on impact of climate change and identification of varieties tolerant to abiotic stresses

TECHNOLOGIES DEVELOPED:

  • Breaking of rice seed dormancy: Methods to break Rice seed dormancy were developed and recommended to the farmers. The technique of Nitric acid treatment for breaking seed dormancy is widely accepted and followed by farmers. The technique involves soaking the seed in 0.63 % Nitric acid solution for 24 hours.
  • Involved in “National Methane gas campaign” and contributed significantly in quantifying the Methane gas emission in low land rice fields of Godavari delta, through ICAR – AP Cess Fund project entitled “Methane Emission in Rice based cropping system”.
  • Identification of donors for various ecological / stress situations like Moisture stress, Water logging, Low light intensity, Seed dormancy, High density grain, Grain shattering etc., so as enable Breeders for utilizing in hybridization programme.
  • Evaluation of rice varieties under natural moisture stress condition has lead to the identification and release of MTU 9993 and MaruteruSannalu (MTU 1006) for rain-fed rice ecosystem.
