Dr. Rajendra Prasad Central Agricultural University, Pusa

In the imperial Gazetteer of India 1878, Pusa was recorded as a government estate of about 1350 acres in Darbhanba. It was acquired by East India Company for running a stud farm to supply better breed of horses mainly for the army. Frequent incidence of glanders disease (swelling of glands), mostly affecting the valuable imported bloodstock made the civil veterinary department to shift the entire stock out of Pusa. A British tobacco concern Beg Sutherland & co. got the estate on lease but it also left in 1897 abandoning the government estate of Pusa. Lord Mayo, The Viceroy and Governor General, had been repeatedly trying to get through his proposal for setting up a directorate general of Agriculture that would take care of the soil and its productivity, formulate newer techniques of cultivation, improve the quality of seeds and livestock and also arrange for imparting agricultural education. The government of India had invited a British expert. Dr. J. A. Voelcker who had submitted as report on the development of Indian agriculture. As a follow-up action, three experts in different fields were appointed for the first time during 1885 to 1895 namely, agricultural chemist (Dr. J. W. Leafer), cryptogamic botanist (Dr. R. A. Butler) and entomologist (Dr. H. Maxwell Lefroy) with headquarters at Dehradun (U.P.) in the forest Research Institute complex. Surprisingly, until now Pusa, which was destined to become the centre of agricultural revolution in the country, was lying as before an abandoned government estate. In 1898. Lord Curzon took over as the viceroy. A widely traveled person and an administrator, he salvaged out the earlier proposal and got London’s approval for the appointment of the inspector General of Agriculture to which the first incumbent Mr. J. Mollison (Dy. Director of Agriculture, Bombay) joined in 1901 with headquarters at Nagpur The then government of Bengal had mooted in 1902 a proposal to the centre for setting up a model cattle farm for improving the dilapidated condition of the livestock at Pusa estate where plenty of land, water and feed would be available, and with Mr. Mollison’s support this was accepted in principle. Around Pusa, there were many British planters and also an indigo research centre Dalsing Sarai (near Pusa). Mr. Mollison’s visits to this mini British kingdom and his strong recommendations. In favour of Pusa as the most ideal place for the Bengal government project obviously caught the attention for the viceroy.

    In-vitro regeneration studies in strawberry (Fragaria x ananassa) cv. Winter Dawn
    (RPCAU, Pusa, 2023) CHAKRABORTY, ARPAN; Kanth, Neeharika
    The strawberry (Fragaria x ananassa Duch.) is one of the most notable tart, sweet and juicy fruits in the world. It is the second-largest berry fruit produced globally, after grapes. As it spreads viral infection, the traditional method of strawberry multiplication by employing runners has some limitations. In order to create an effective technique for multiple shoots, root induction and proliferation and regeneration of strawberry plants using explants of runner tip and nodal segments, the current experiment was carried out. The present investigation entitled “In-vitro regeneration studies in strawberry (Fragaria × ananassa) cv. Winter Dawn” was carried out during 2022-2023 in Plant tissue culture laboratory, SRI, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur (Bihar). The variety Winter Dawn was used for the present study. The two types of explants used were runner tip and nodal segments. The three experiments: sterilization, shooting protocol and rooting protocol were carried out. For sterilization, mercuric chloride and ethanol were used and their effects were investigated. The shoot regeneration study was carried out with different concentrations of BAP was employed at concentrations of 0.5, 1.0, 1.5, and 2.0 mg/l, Kinetin at 0.2, 0.4, 0.6, and 1 mg/l and GA3 at 0.2, 0.4, 0.6 and 1 mg/l. The rooting protocol was standardized using NAA and IBA at varying concentrations (0.5, 1.0, 1.5, 2.0 mg/l). The runner tips were found to be better in every experiment carried out. BAP levels of 1.5 and 0.6 mg/l Kinetin exhibited better than any other combination in case of shoot regeneration and the medium enriched with NAA at 0.5 mg/l gave good results compared to other combinations.
