Abstract/ Executive Summary:

It appears that all the seven lines had significantly taller height than the check variety, Binadhan-7 at all locations. Though the number of effective tiller of the mutants was higher, there were no significant differences between the mutant lines and the check variety. At Mymensingh, one line had significantly longer panicle length than the check variety and four lines had significantly higher filled grains than the check variety while at Comilla two and Magura five lines had higher filled grains. Only one line, RC(2)-2-4-1-4 produced significantly higher grain yield than the check variety at Mymensingh.

Keywords: Fine rice, Higher iron content, F7 lines, T. aman

Location: BINA farm, Mymensingh and BINA sub-station farms at Magura, Rangpur and Comilla

Start Date: 01-07-2013

End Date: 30-06-2014

Program Area: Variety and Species

Commodity: Rice

Objectives:

To assess the yield performance of F₇ lines of fine grain and higher iron containing rice in T. aman season over different locations of Bangladesh to assess the yield performance of F₇ lines of fine grain and higher iron containing rice in T. aman season over different locations of Bangladesh

Methodology:

This experiment was carried out with seven high yielding and iron containing T. aman rice lines, derived from hybridization between an exotic line introduced from Vietnam having high iron content and Binadhan-7 or Binasail, to assess performance over different locations of Bangladesh. Binadhan-7 was used as a check variety. Seeds were sown during 07 July and 17 July 2013 and transplanted during 30 July and 08 August 2013 at different locations. The experiment was carried out following RCB design with three replications having plot size 3.0 m x 2.0 m. Recommended doses of nitrogen, phosphorus, potassium, sulphur and zinc were applied in the form of Urea, TSP, MOP, Gypsum and Zinc Sulphate. Cultural and intercultural practices were followed as and when necessitated. The experiment was carried out following RCB design with three replications. The size of the unit plots were 3.0 m x 2.0 m. Seedlings were transplanted at 15 cm distance within rows of 20 cm apart. Recommended doses of nitrogen, phosphorus, potassium, sulphur and zinc were applied in the form of Urea, TSP, MOP, Gypsum and Zinc Sulphate. Cultural and intercultural practices were followed as and when necessitated. Data on plant height, number of effective tiller, panicle length, and filled and unfilled grains panicle^-1 were recorded after harvest from 5 randomly selected competitive plants. Maturity was assessed plot basis. Grain yield data were recorded from an area of 1.0 m² which was later converted to tha^-1.
