BREEDING TRIALS
Breeding Trials
North Zone Trials
- Br. 22a – Initial Evaluation Trial of G. arboreum (Irrigated)
- Br 25a/b – Preliminary Hybrid Trial of Desi Hybrid
- Br 04a – Coordinated Varietal Trial – G. hirsutum
- Br 24a – Coordinated Variety Trial – G. arboreum
- Br 25a/b – Coordinated Hybrid Trial of Desi Hybrid
Significant Achievements: 2022-23
- In Initial evaluation trials of North Zone, G. arboreum culture FDK 341 (2836 kg/ha) and desi hybrid KR 160 (3553 kg/ha) were topping in seed cotton yield in the respective trials and have been promoted to coordinated trials.
- In Coordinated variety trial of G. hirsutum in North Zone, the zonal check variety F2228 was the best with 2332 kg/ha seed cotton yield. Among desi cotton, FDK 312 with a mean seed cotton yield of 2669 kg/ha was promising among varieties and KR 150 with a mean yield of 3120 kg/ha was promising hybrid.
Central Zone Trials
- Br. 22b – Initial Evaluation Trial of G. arboreum
- Br 32b – Initial Evaluation Trial of G. herbaceum
- Br 03a – Preliminary Varietal Trial –Coloured G. hirsutum
- Br 24b – Coordinated Variety Trial – G. arboreum
Significant Achievements: 2022-23
- In Initial evaluation trials of Central Zone, the G. arboreum culture CNA 1085 with a mean seed cotton yield of 1340 kg/ha was the best. However, in G. herbaceum trial, none of the test cultures were superior to the check varieties.
- In Central Zone trials, among the coloured genotype CCH 20449 was the best recording a mean seed cotton yield of 2242 kg/ha and have been promoted to coordinated trials.
- Similarly, among G. arboreum cultures, white linted AKA 2016-11 recorded the highest mean seed cotton yield of 1245 kg/ha and CNA 20402 was the best with 1129 kg/ha among brown linted genotypes.
South Zone Trials
- Br. 22a – Initial Evaluation Trial of G. arboreum (Irrigated)
- Br 25a/b – Preliminary Hybrid Trial of Desi Hybrid
- Br 04a – Coordinated Varietal Trial – G. hirsutum
- Br 24a – Coordinated Variety Trial – G. arboreum
- Br 25a/b – Coordinated Hybrid Trial of Desi Hybrid
Significant Achievements: 2022-23
- In South Zone trials, among coloured hirsutum genotypes, Vaidehi 1, the check was the best for yield, whereas in coordinated variety trial of white linted genotypes, RAH 1081 was the best with a mean seed cotton yield of 1993 kg/ha under irrigated conditions.
- Among ELS barbadense cultures, CCB 22-2 with a mean seed cotton yield of 584 kg/ha was the best under irrigated conditions, whereas in rainfed conditions, among arboreum cultures, DWDa 2252 was the topper recording a mean seed cotton yield of 824 kg/ha.
- In the pre-breeding activities, new crosses between cultivated species and wild species were attempted in different participating centres and different degree of success was reported.
- Introgressed segregating lines with different target characters were shared among the participating centres and their performance is reported.
- Similarly, the shared introgression lines were utilized as donor parents for target characters and crossed with agronomically superior varieties in participating centres
