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.

    Genetic Divergence and Cause Effect Analysis Under Drought Condition on Chickpea
    (Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, 2018) Kumar, Rupesh; Singh, Ajay Kumar
    The present investigation entitled “Divergence and cause effect analysis under drought condition on chickpea” was carried out by using forty one genotypes including check in RBD with two replication at rainout shelter farm of RPCAU Pusa Samastipur. Investigation on eighteen characters were done viz. days to 50% flowering, plant height, number of primary branch per plant, number of secondary branch per plant, number of pods per plant, number of seeds per pod, harvest index, yield per plant, number of nodules per plant, nodule weight per plant, nodule dry weight per plant, root length, root volume, root dry weight, peroxidase, catalase, protease and proline. The observations were recorded based on five randomly selected plants from each plot of the replication and standard recommended statistical procedures were used to estimate the genetic parameters. The analysis of variance revealed that the genotypes had shown the significant differences among themselves for all characters. Wide range of variability was recorded for the traits yield per plant followed by pod per plant, root dry weight and nodule weight per plant indicating the presence of ample amount of variability in the experimental material. In general phenotypic coefficient of variation (PCV) was slightly higher in magnitude than genotypic coefficient of variation (GCV) suggesting that expression of the characters are being controlled by genotype itself. High heritability coupled with high genetic advance was observed for the trait such as number of pods per plant, harvest index, yield per plant, nodule weight per plant, root length, root dry weight, peroxidase and proline content, indicating the preponderance of additive gene action thus simple selection may be rewarding. Pods per plant and peroxidase exhibited positive and significant correlation with the grain yield along with their high and positive direct effect as harvest index, catalase, protease and proline content also exhibited positive and significant correlation with yield owing to the positive and high indirect effect via pod per plant suggesting that the these traits may be considered during the course of selection for enhancement of yield in chickpea. Maximum inter cluster distance was observed between cluster III and cluster VII suggesting that the he genotypes placed in these clusters are most divergent one and so as to have the heterotic recombinant these parents may be used in crossing program. Flip-10-144C in cluster VI had higher cluster mean for most of the yield attributing traits, so, this genotype may be used as donor to incorporate the respective traits in the recipient variety. Proline has contributed maximum towards divergence followed by protease content, catalase content and nodule weight per plant.
