Abstract/ Executive Summary:

An experiment was conducted at Regional Pulses Research Station (RPRS), BARI, Madaripur during Rabi 2017-18 to find out the suitable and high yielding genotypes/variety of grasspea against rust and powdery mildew. Six genotypes/lines including one check BARI Kheshari-3 were evaluated in the trial. The result revealed that all the germplasm showed resistant reaction against powdery mildew. Rust was not developed among the entries. The line BGP-130010 gave the highest yield (1654 kg/ha) and the lowest yield (1208 kg/ha) was obtained from BGP-13007.

Keywords: Pulses, Lentil, Grain yield, Grasspea, BARI Kheshari-3, Diseases

Location: RPRS, Madaripur, Bangladesh

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Crop-Soil-Water Management

Commodity: Gardenpea, Diseases

Objectives:

To screen disease resistant and high yielding germplasm.

Methodology:

The experiment was conducted at RPRS, Madaripur during Rabi season of 2017-18 to find out the suitable germplasm of grasspea. There were 250 grasspea germplasms collected from PRC, Ishurdi, Pabna in 2013-14 and screened at RPRS, Madaripur. From result of that year, 10 best performed lines were screened again in 2016-17. In that year, from ten germplasms six were selected considering their yield parameters. In this year, six those germplasms including one check BARI Kheshari-3 were evaluated for second year. Six germplasms were viz. BGP-13004, BGP-13006, BGP-13007, BGP-13008, BGP-13009 and BGP-13010. The experiment was laid-out in Randomized Complete Block Design (RCBD) with three replications. The unit plot size was 4m × 4m and spacing was 40 cm×05 cm. Seeds were sown in the rows carefully by hands at 3 cm depth and covered by soils on 21 November 2017. All recommended fertilizers were applied as basal dose during final land preparation. Powdery mildew (Erysiphe poligoni or Oidium sp.) of mungbean was recorded on a 0-5 scoring scale (Gawande and Patil, 2003) used in this experiment. The scale described as Voliam Flexi 300SC (0.1%) was sprayed for control of thrips and pod borer. The crop was harvested after maturity. Data on yield contributing characters were recorded from 10 randomly selected plants from each plot. Grain yield (kg/ha) was recorded from the whole plot. Data were analyzed statistically by using MSTAT-C program.

Achievement/Findings:

With the findings of the study it could be concluded that among the tested genotype BGP-130010 produced highest grain yield (1654 kg/ha) followed by (1415 kg/ha) in BGP-13006. Both genotypes also performed resistant reaction against powdery mildew disease. So, the genotype BGP-13006 and BGP-130010 could be used for crop improvement.
