|---|---|---|---|
| 1 | PIE13001MI “All India Coordinated Experimental Trials for Mulberry (AICEM) –Phase-IV” | June 2019-March 2025 | AGB8 variety with high leaf yield and quality under irrigated condition evaluated at 7 centers under AICEM-IV |
| 2 | PIE01022SI: Evaluation of promising mulberry genotypes for higher leaf yield and resistance to root rot and root knot diseases in Primary Yield Trial | Dec. 2021- May 2026 | Identified productive genotypes with resistance to root rot and root knot diseases. |
| 3 | PPA4715: Effect of plant growth promoting rhizosphere microorganisms on leaf nutrient content of primary tasar host plants in forest and block plantation | Sept. 2016 -March, 2021 |
1. Generated information on the status of PGPR composition in tasar food plants rhizosphere grown in block plantation and forest 2. Relationship between PGPM and nutrient content of soil and leaf of tasar host plants was revealed in tasar rearing regions of 3 states 3. Eight P-Solubilizing Bacteria: PSB 7-2 (Enterobacter cloacae), PSB 16-2 (Enterobacter hormaechei), PSB 64-7 (Acenetobacter pittii), PSB 98-1 (Enterobacter cloacae), PSB 109-1 (Enterobacter tabaci), PSB 110-2 (Enterobacter asburiae), PSB 115-5 (Acenetobacter pittii) 4. KBB 57-5 (Serratia marcescens) having anti-pathogenic and plant growth promotion property. 5. Five Nitrogen fixing bacteria with IAA production capacity: NFB5-2 (Bacillus subtilis), NFB8 (Burkholderia cepacia), NFB18-2 (Serratia marcescens), NFB51-2 (Enterobacter asburiae) and NFB 106-2 (Providencia vermicola) |
| 4 | AIB-4717: Improvement of tropical tasar silkworm for high silk yield through recurrent selection | 2016-2019 |
• Semi-domestic Daba (adaptability) was crossed with Wild Daba (silk yield and fecundity) to introgress beneficial traits into the base population. Operated two recurrent selection cycles • Genetic parameters were estimated to frame selection strategies; shell weight showed low heritability and low genetic advance. • Findings indicated the need for more selection cycles to realize meaningful genetic gains. • Results emphasized maintaining a large effective population size across cycles as studied sample exhibited inbreeding depression. • Tasar silkworm populations follow Hardy–Weinberg equilibrium under large, randomly mating conditions. However, small population size and sampling effects can lead to deviations from equilibrium and promote inbreeding. |
| 5 | PIB-4697: Development of superior hybrids of Terminalia. arjuna and T. tomentosa for high leaf yield and quality. | 2012 - 2018 |
• A seedling orchard with five superior accessions was established. • Genetically diverse parents were crossed to develop 62 inter- and intra-specific hybrids. • Ten superior hybrids were selected based on cumulative performance for key growth and yield traits. • Hybrids with high bio-chemical content were also identified and selected. |
