Regeneration Efficiency

This study was undertaken to establish a regeneration protocol for two scented indica rice varieties, namely Pusa Basmati1 and Kalanamak. Callus culture in Pusa Basmati1 was initiated in MS containing 2.0 mg/l of 2,4-D. Optimum requirement of growth hormones for callus induction in Kalanamak was 1.5 mg/l of 2,4-D supplemented with 0.1 mg/l each of NAA and BAP in MS. Shoot regeneration in Pusa Basmati1 initiated in MS containing 2.0 mg/l BAP, 0.5 mg/l each of NAA and Kn. There was no shoot initiation in MS with same composition in Kalanamak. The shoot regeneration was successfully initiated and achieved in Dl medium supplemented with 2.0 mg/l BAP, 0.2 mg/l each of IAA, NAA and Kn, 500 mg/l each of proline and glutamine and 800 mg/l casein hydrolysate. The calli derived from mature seed embryo produced fertile green plants. The plants were successfully transferred to field with normal flowering.

An efficient plant regeneration system from embryogenic callus of two elite indica rice (Oryza sativa spp. indica) varieties of Northeast India, Ketokijoha and Monoharsali is established. The effect of auxin, 2,4-dicholorophenoxy acetic acid (2,4-D) on callus induction was optimized. Friable, nodular and creamish-white embryogenic calli were induced from mature seeds on NB medium supplemented with 2.5 mg/l 2,4-D. Plants were regenerated from 40-50 days old embryogenic callus on NB medium containing 0.5 mg/l BAP (6-benzylaminopurine) and 0.25 mg/l ABA (abscisic acid). Regenerated plants with multiple tillers were rooted on half strength MS medium and rooted plants were acclimatized with 94% survival rate. Higher frequency of callus induction as well as plant regeneration was recorded in Ketokijoha as compared to Monoharsali. The calli of both the varieties were found amenable to Agrobacterium-mediated transformation as evident from strong GUS (β-glucuronidase) expression. The results may find wide application for genetic improvement for valuable traits these elite indica rice varieties of Northeast India. Int J Appl Sci Biotechnol, Vol 3(4): 680-686

In Vitro Response

In vitro response of four local Indica rice cultivars viz. Sadamota, Kachamota, Moulata and Dudhkalam was evaluated. The aim of this study is to develop an efficient protocol for callus induction, plant regeneration and to observe the effect of gamma radiation on plant regeneration for creating possible genetic variability. In Different concentration of 2,4-D and growth regulators were supplemented with MS medium (Murashige and Skoog’s) to observe their callus induction frequency using mature embryo as explant. Among the cutivars, the highest primary callus (92.55%) as well as embryogenic callus induction (56.26%) was showed in sadamota at 3.0 mgl-1 2,4-D and 10 mgl-1 kinetin under dark condition. Twenty one days old embryogenic calli were exposed to 0, 2, 4 and 6 Gy of gamma rays and transferred to regeneration medium. Both callus growth and regeneration capacity were found to be decreased with increasing level of exposure to gamma rays. The doses of 4 Gy of gamma radiation were found to be the 50% inhibition dose for callus growth and plant regeneration in sadamota and kachamota, repectively whereas the 50% inhibition dose for moulata and dudhkalam at 2 Gy. This results indicate that sentivity of gamma radiation on rice callus depends on genotype of a genus.
