Abstract/ Executive Summary:

A field experiment was conducted at RARS, Rahmatpur, Barishal during the Rabi season of 2019-20 to evaluate the local and exotic germplasm of grasspea genotypes/lines. Eight selected grasspea local and exotic lines viz. IGYT-125, IGYT-120, IGYT-124, IGYT-122, IGYT-110, IGYT-115, IGYT-123, IGYT-216, and one check variety BARI Kheshari-3 were evaluated in the trial. Results showed that all the characters under this study were not significantly different among the genotypes except the number of pod/plant and seed yield. . The highest seed yield was produced by the entry IGYT-216 (1790.4 kg/ha) and IGYT-125 (1783 Kg/ha) which is statistically identical to check variety BARI Kheshari-3 (1534.8 Kg/ha), IGYT-122 (1460.9 Kg/ha) and IGYT-123 (1446.7 Kg/ha). The lowest seed yield (556 kg/ha) was obtained in IGYT-115.

Keywords: Evaluation, Exotic germplasm, ICARDA, Grasspea

Location: RARS, Rahmatpur, Barishal

Start Date: 00-00-2019

End Date: 00-00-2020

Program Area: Variety and Species

Commodity: Grasspea

Objectives:

This program has been planned to evaluate some local and exotic germplasm from ICARDA to make a suggestion to include progressive lines for varietal improvement.

Methodology:

The experiment was conducted at the experimental field of Regional Agricultural Research Station (RARS), Rahmatpur, Barishal in the rabi season, 2019-20 to evaluate the performance of grasspea local and exotic genotypes/lines for searching of high yielding and disease resistant variety. Eight selected grasspea lines viz. IGYT-125, IGYT-120, IGYT-124, IGYT-122, IGYT-110, IGYT-115, IGYT-123, IGYT-216, and one check variety BARI Kheshari-3 were evaluated. The experiment was laid out in Randomized Complete Block Design with three replications. The unit plot was 4 rows and 3m long with spacing 50cm×5cm. Seeds were sown in the rows on 30^th November 2019. Two weeding were done at 25 days and 45 days after sowing. 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 R software at a 5% level of significance.

Achievement/Findings:

The tested grasspea variety/genotypes differ significantly from one to another in respect of growth and yield contributing performances under field conditions. Data revealed that plant population/plot, days to flowering, days to maturity, plant height, and hundred seed weight did not differ significantly among genotypes. The plant population/plot was ranged from 165 to 226. Days to flowering was ranged from 60-66 days. Days to maturity for grasspea genotypes was ranged from 103 to 111 days. The 100 seed weight ranged from 5 to 6 g. The number of pods/plants had differed significantly. IGYT-125 and IGYT-216 had produced the highest number of pods/plant (40 and 36, respectively) whereas IGYT-110 had produced the least number of pods/plant (17.4). The seed yield ranged from 556 to 1790.4 Kg/ha. The highest seed yield was produced by the entry IGYT-216 (1790.4 kg/ha) and IGYT-125 (1783 Kg/ha) which is statistically identical to check variety BARI Kheshari-3 (1534.8 Kg/ha), IGYT-122 (1460.9 Kg/ha) and IGYT-123 (1446.7 Kg/ha). The lowest seed yield (556 kg/ha) was obtained in IGYT-115. With findings of the present study, it could be concluded that the genotype IGYT-216 and IGYT-125 had produced the highest seed yield (1790.4 kg/ha and 1783 kg/ha, respectively) which was statistically identical with check variety BARI Kheshari- 3 (1534.8 kg/ha). So, the genotype IGYT-216 and IGYT -125 can be considered for further investigation.
