Abstract/ Executive Summary:

Viability of 954 accessions of bottle gourd, spinach, maize, bitter gourd, sweet gourd, mung bean, muskmelon, hyacinth bean, chilli, amaranth, brinjal, snake gourd, barley, soybean, radish, and foxtail millet were tested during 2015-16 from active collection. The viability test was conducted on germination paper at 30 to 35⁰C at dark condition for 7 to 14 days. Out of 954 accessions, 206 accessions were in <40%, 264 accessions in 40-79% and 484 accessions in 80-100% germination. Among the accessions of bottle gourd-39, spinach-16, maize-46, sweet gourd-8, mung bean-31, muskmelon-39, hyacinth bean-36, amaranth-109, snake gourd-26, barley-40, and soybean-34 were found high germination percentage (80-100%). But the germination percentage of bitter gourd, chilli, brinjal, radish, and foxtail millet were observed poor (<40%). The accessions having less than 80% germination will be regenerated in the next year.

Keywords: Regeneration, Multiplication, Accession, Active collection

Location:

Start Date: 00-00-2015

End Date: 00-00-2016

Program Area: Conservation and Biodiversity

Commodity: Plant

Objectives:

The objective of monitoring is to determine whether regeneration or multiplication of accession is required

Methodology:

The accessions of different crops such as of bottle gourd, spinach, maize, bitter gourd, sweet gourd, mung bean, muskmelon, hyacinth bean, chilli, amaranth, brinjal, snake gourd, barley, soybean, radish, and foxtail millet were tested for germination from active collection of 2006 to 2009. In July 2015 to June 2016, all the samples were put into germination paper for viability test. Number of normal seedling and dead seeds were counted and viability (%) was calculated. The accessions of the crops should be regenerated in the next year whose germination less than 80%.

Achievement/Findings:

The viability of 954 accessions of bottle gourd, spinach, maize, bitter gourd, sweet gourd, mung bean, muskmelon, hyacinth bean, chilli, amaranth, brinjal, snake gourd, barley, soybean, radish, and foxtail millet was tested during 2015-16. Out of 954 accessions, 206 accessions were found in <40%, 264 accessions in 40-79% and 484 accessions in 80-100% germination. Among the accessions of bottle gourd-39, spinach-16, maize-46, sweet gourd-8, mung bean-31, muskmelon-39, hyacinth bean-36, amaranth-109, snake gourd-26, barley-40, and soybean-34 were found high germination percentage (80-100%). But the germination percentage of bitter gourd, chilli, brinjal, radish, and foxtail millet were observed poor. The accessions having less than 80% germination will be regenerated in the next year.
