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.

    Molecular characterization and stability study in Indian mustard (Brassica juncea L.) genotypes under early and terminal heat stress
    (DRPCAU, Pusa, 2019) YADAV, SUMAN; PANDEY, ANIL
    Present study entitled “Molecular characterization and stability study in Indian mustard (Brassica juncea L.) genotypes under early and terminal heat stress” conducted under early-timely—late-sown environments during Rabi 2017-18 and 2018-19 at research farm of TCA Dholi. The twenty genotypes belonging to various geographic locations and diverse pedigree reflected their genetic worth for thirty five morpho-physio-biochemical traits exhibiting sufficient variability. PCV higher than GCV revealed varying environmental influence. High h2 bs and GAM for LMSI, TSS, PA & PC in early and terminal stress conditions showed preponderance of additive gene action. Positive and significant association of VPD, DFFO, D50%F & DPM while, negative with PAPD expressed their phonological inter-relationship and more usefulness of VPD & PAPD for terminal heat stress condition. SYP positively with HI, EL, CC & PH (and also between EL & CC); while, negative with H.T.E. (early & terminal heat stress); OC, SPB & PC (early-sown) whereas, SI & H.S.I. (late-sown). SI & H.S.I. decrease with increased H.T.E. and subsequently, increased SYP can be utilized. HI with high positive direct effect and association was major yield predictor (early & late-sown) alongwith BYP (early) and EL, RWC & CC (terminal) heat stresses. On Tocher‘s, Canonical (vector) and K-mean clustering, Rajendra Sufalam and Urvashi (oligo-genotypic) alongwith RAURD-14-18, BPR-541-4, DRMR4001, DRMR-15-9, RGN-368, RGN-13, PRE-2013-19 and KMR (E)16-1 were divergent genotypes and also reflected desirable per se for various morpho-physio-biochemical traits. Nine crosses between divergent parents suggested 5 crosses involving DRMR-15-9, RAURD-14-18, BPR-541- 4, DRMR4001 & RGN-368 with Urvashi; and 4 crosses involving RGN-13, RGN-368, PRE-2013-19 & KMR (E) 16-1 with Rajendra Sufalam. PA & H.T.E. contributed maximum towards total divergence under both stress environments. Molecular diversity analyses also reflected PRE-2013-19, KMR (E)16-1 & RAURD-14-18 as divergent as well as genotypes with unique alleles; whereas, DRMR-15-9, Rajendra Sufalam and RGN-368 as genotypes with unique alleles. Thus, reflecting their overall usefulness as divergent genotypes. NI2A09, showed best polymorphic bands, highest (0.636) PIC values and four alleles per locus and can be effectively utilized for studying diversity of Indian mustard genotypes. Studied genotypes reflected variability in all six environments except for CT & RGR. Rajendra Sufalam offered stability under poor environment and found most suitable genotype for terminal heat stress-late-sown & timely-sown conditions. Also it was only stable stable (rich environment) genotype for oil content overall six environments as well as diverse stable parent with superior per se for many traits including SYP. RGN-13 with average and rich environment stability in early-timely and late-timely-sown conditions whereas, RAURD-14-11 and BPR-541-4 (rich environment stability) suitable for farmers for both early and late-sown with timely-sown agroecologies of Bihar. Suggested Indian mustard plant type for heat stress condition, the emphasis is required towards seedlings and early growth stages before flowering (SDW-VPD-DFFO), PAPD, DPM, high: LPMA, PBP, SPMA, SPB, SL, TSW, RWC & CC including SI, H.S.I. and H.T.E.
