  1. Two SI based hybrids of cabbage viz., KTCBH-51 and KTCBH-81 and one CMS based hybrid KTCBH-84 are under evaluation in AICRP (VC) trials.
  2. In cauliflower, Ogura male sterile cytoplasm has been introgressed into 20 new background of cauliflower. Two Self-incompatible (SI) lines have been developed for use in hybrid seed production.
  3. In cauliflower, refined breeding methods for development of CMS lines with good seed setting capacity and honey bee activity have been standardised.
  4. Based on these lines, few promising F1 hybrids (KTH-27, KTH-52, and KTH-51) are under pipeline. Besides Ogura, few other male sterile cytoplasms like, Trachystoma ballii, Diplotaxix catholica, Diplotaxix berthauttii and Brassica tournefortii are in the process of introgression through in vitro embryo rescue.
  5. Inter-genomic introgression of black rot resistance genes from A and B genomes of brassicas through embryo rescue is in progress.
  6. Effect of introgressed Ogura male sterile cytoplasm on various vegetative, commercial and floral traits of cauliflower inbred lines and F1 hybrids have been determined. 
  7. In late cauliflower, a large collection of genotypes are maintained and characterised for various commercial and nutritional traits.
  8. One promising line ‘KTK-64’ of kale is in multi-location testing under the AICRP (VC).
  9. Eighty germplasm of snowball cauliflower, 66 lines of cabbage, 40 of temperate carrot & 51 of capsicum were maintained after positive selection for desirable traits.
  10. Three stable CMS (Ogura) lines of snowball cauliflower were developed and are being used in development of F1 hybrids.
  11. Selections KS-12, KS-13, KS-15, KS-20, KS-21 and KS-22 were developed by purification for use as pollinator (C) lines in hybrid development.
  12. For hybrid seed production of carrot female: male ratio of 8:2 was found suitable.
  13. Seventeen hybrids of Asiatic lily, five of oriental lilies and four selections of LA- hybrids were evaluated. In alstroemeria, eight cultivars were evaluated and maintained.
  14. In a 4x4 complete diallel cross among lilium, maximum seed set was recorded in a combination of ‘Alaska x London’ while when we take pollination method in consideration a general trend of seed set was maximum in stigmatic, stylar cut, stylar implant.
  15. Different intervarietal lilium hybrids were developed and evaluated. Hybrids PKLH-1, PKLH-5 and PKLH-7 were found promising in respect of vegetative and flowering characters.
  16. Among different intervarietal crosses earliest seed germination (12.3 days) was observed in a cross combination between ‘Shraj x Sumplan’ whereas maximum seed germination (57.6%) was found in ‘Pollyanna x Shiraj’ cross combination.
  17. Evaluation of Interspecific crosses among Oriental x Asiatic lilium is in progress.
  18. In Lilium cv. ‘London’ maximum vase life was recorded with AgNO3 (100 ppm). Post harvest leaf yellowing was significantly delayed up to 21 days with cow urine (2.5 ml) + 2% sucrose.
  19. In alstroemeria cv. ‘Aladdin’ it was found that cut stems held in GA3 (75ppm) + BA(75ppm) delayed the onset of flower senescence as measured by days to 50% petal fall and days to 50% leaf yellowing.
  20. Sand and IBA (200ppm) was found the best media for scale propagation of lilium.
  21. A significant reduction in time taken to flowering was recorded with prolonged storage of bulb at 2 and 40C temperature.
  22. On the basis of 600 respondents from 30 villages revealed that the majority (50.50%) of the farmers represented the middle age group (40-60 years). 
  23. Most of the farmers were matric (33%), followed by primary education (25.67%). The gap between the recommended and adopted technologies was observed to be 62.47%.
  24. Low price of the farm produce and high incidence of insect-pests and diseases were the major constraints in vegetable production.
