Abstract/ Executive Summary:

The monitoring of 809 accessions from the different year (batch references) among seven important crops viz. Sorghum (268), Indian spinach (73), groundnut (23), sunflower (56), ash gourd (250), bitter gourd (135), and batishak (4) were tested in 2019-20 by germination test. Among the monitored germplasm, 445 accession from the active collection and 364 accessions were from the base collection. The viability test was conducted on germination paper, sands, and pulverized gravels. Combining all data, it was found that less than 40% germination was higher but 41-80% germination and 81-100% germination were found lower in the case of active collection. Moreover, less than 40% germination was lower but 41-80% germination and 81-100% germination was found higher in the case of the base collection. Collectively, base collection performance was good over the active collection. The accessions having less than 80% germination and or less quantity will be regenerated in the following year.

Program Area: Conservation and Biodiversity

Commodity: Plant

Objectives:

The objective of monitoring is to check the viability and quantity of conserved germplasm.

Methodology:

The accessions of seven crops such as sorghum, Indian spinach, groundnut, sunflower, ash gourd, bitter gourd, and batishak were tested for germination from the active and base collection from 1996 to 2016. The germination test was conducted in a tray by placing germination paper, sands, grinded gravels, and rocks. In each accession, a minimum of 10-50 seeds was placed for germination test based on their quantity conserved. The number of normal seedlings, abnormal seedlings, dormant and dead seeds was counted and viability (%) was calculated

Achievement/Findings:

The viability of 809 accessions from different batch references (1996-2016) among seven important crops viz. sorghum (268), Indian spinach (73), groundnut (23), sunflower (56), ash gourd (250), bitter gourd (135) and batishak (4) was tested in 2019-20 by germination test. Among the monitored germplasm, 445 accession from the active collection and 364 accessions were from the base collection. The viability of 809 accessions of seven important crops was monitored by a germination test. Among the monitored germplasm, 445 accessions were taken from the active collection and 364 accessions were from the base collection. Combining all data, it was found that less than 40% germination was higher but 41-80% germination and 81-100% germination was found lower in the case of active collection. Moreover, less than 40% germination was lower but 41-80% germination and 81-100% germination was found higher in the case of base collection. Collectively, base collection performance was good over the active collection. Monitoring is an integral part of the conservation of germplasm. The overall result implies that base collection material showed better performance than active material. So, more attention is to be taken for active collection. The accessions having less than 80% germination and or insufficient quantity will be regenerated in the next year.
