Abstract/ Executive Summary:

The experiment was conducted at different locations such as Barisal, Comilla, Rangpur and Satkhira. Eight promising hybrids with three checks were evaluated both head quarter and four regional stations.Thirty days old seedlings were transplanted in 30m² sized plot following RCB design with 3 replications using single seedling per hill and spacing were 20 cm x 15 cm. The experiment were investigated to study the adaptability and yield potentiality of the identified hybrids.The results showed that the BRRI 1A/BRRI 12R and BRRI 10A/BRRI 12R gave yield advantage by 1.38 to 2.31 t/ha and 0.96 to 2.13 t/ha respectively over check BRRI dhan28 with apparently similar growth duration. Another combination BRRI 10A/BRRI 13R showed yield advantage similar to the combinations but in comilla it out yielded 8.22 t/ha where BRRI dhan28 was 5.66 t/ha.

Keywords: Multilocation Trial, Stability, Hybrids rice

Location: Gazipur, Comilla, Satkhira, Barisal and Rangpur

Start Date: 15-11-2009

End Date: 25-05-2010

Program Area: Variety and Species

Commodity: Rice

Objectives:

To study the adaptability and yield potentiality of the identified hybrids.

Methodology:

Eight promising hybrids were evaluated both in BRRI head quarter and four regional stations (Barisal, Comilla, Rangpur and Satkhira) with BRRI dhan28 and BRRI dhan29 as check.Thirty days old seedlings were transplanted in 30m² sized plot following RCB design with 3 replications using single seedling per hill. Spacing were 20 cm x 15 cm. Fertilizers were applied @ of 270:130:120:70:10 kg/ha Urea ,TSP, MP, gypsum and ZnSO₄ respectively. Others necessary operation were done when it required.

Achievement/Findings:

The results showed that the BRRI 1A/BRRI 12R and BRRI 10A/BRRI 12R gave yield advantage by 1.38 to 2.31 t/ha and 0.96 to 2.13 t/ha respectively over check BRRI dhan28 with apparently similar growth duration. Another combination BRRI 10A/BRRI 13R showed yield advantage similar to the combinations but in comilla it out yielded 8.22 t/ha where BRRI dhan28 was 5.66 t/ha.
