Abstract/ Executive Summary:

Participatory variety selection (PVS) trials were conducted at Godagari of Rajshahi and Nachole of Chapai Nawabganj districts during Aman 2008. Objective of this study was to evaluate and select rice genotypes tolerant to drought stress through farmer's participation. The study indicates that BR7155-20-1-3 scored the highest followed by BRRI dhan49 and IR74371-54-1-1 as 2nd and 3rd position, respectively. The preference points of farmer's were high tillering, high number of grain/panicle, high yield, strong stem, medium plant type, fineness of grain, expectation of high market price, early maturity, less disease infestation. Farmers confirmed that they never sacrifice yield at the cost of short duration. BRRI dhan49 showed the preference at both sites. Similarly, BRRI dhan33 and BINA dhan7 were preferred at Godagari and it could be upscale there. The remaining varieties/lines viz. Barke 3004, IR74371-54-1 and BR7155-20-1-3 should be placed in Baby trials. In addition, these lines could be included in the Mother trial along with new lines. It has been committed to supply 500 g seeds of these lines to respective PVS farmers for growing in their fields under own management as Baby trial in the next T. Aman season.

Objectives:

To evaluate and select rice genotypes tolerant to drought stress through farmer's participation.

Methodology:

Participatory variety selection (PVS) trials were conducted at Godagari of Rajshahi and Nachole of Chapai Nawabganj districts during Aman 2008. A total of 14 genotypes (V1 = IR74371-54-1-1; V2 = IR72667-16-1-B-B-B; V3 = IR74371-46-1-1; V4 = IR55419-04; V5 = IR74371-70-1-1; V6 = IR70215-70-CPA-3-4-1-3; V7 = BR7155-20-1-3; V8 = BRRI dhan49; V9 =BRRI dhan33; V10 =BRRI dhan39; V11 = BINA dhan7; V12 = Barke 3004; V13 = Swarna; V14 = Gutiswarna) were evaluated under rainfed environment. Twenty five-day-old seedlings were transplanted on 13 and 14 August, 2008 in a 5.1 m x 20 row plot with 25 x 15-cm spacing using 2-3 seedlings per hill. The trial was designed in augmented design in non-replicated trial. Fertilizers @ 80: 15: 40: 11: 3 kg/ha NPKSZn were applied in the experiment. P, K, S, Zn and 1/3 N were applied as basal during final land preparation. Rest of the N was top dressed in two equal splits at 20 and 45 Days after transplanting. All other crop management practices were done as and when necessary for proper crop management. Basudin10 G was applied to control stem borer. Twenty three farmers including 5 female along with 11 researchers, extension & NGO personnel were invited to evaluate the genotypes at maturity stage in Godagari while 20 farmers and 4 others took part in Nachole site. The genotypes were labeled with codes and hanged a box for vote. The farmers were briefed about the activity. Each farmer was supplied with 3 positive and 3 negative ballot papers. Also, the farmers were encouraged to put vote fairly. At first, the participants moved around the plots and voted in their own judgments.

Achievement/Findings:

BR7155-20-1-3 scored the highest followed by BRRI dhan49 and IR74371-54-1-1 as 2nd and 3rd position, respectively. So BR7155-20-1-3, Barke 3004 and IR74371-54-1 should be placed in Baby trials.
