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.

    Evaluation of high Sucrose containing Sugarcane Clones under Water-Logging Condition
    (Rajendra Agriculrural University, Pusa (Samastipur), 2015) Kumar, Praveen; Kumar, Balwant
    The present study was undertaken with evaluation of high sucrose containing sugarcane clones under water logging condition (water depth 45 to 60 cm from July to October) involved eighteen sugarcane clones including two checks (BO 91 and CoLk 94184), were planted in Paddy block at Rajendra Agricultural University, Pusa, Bihar, in a Randomized Block Design with three replications during 2014 - 15. The characters studied namely germination % at 45 DAP, number of shoots at 120 DAP, plant height at 150, 240 and 360 days, cane diameter at harvest, number of millable canes, brix, pol and purity % at 10 & 12 month stage, single cane weight, number of aerial roots/ node, length of aerial root, dry weight of aerial roots during the water-logging period and cane yield. Observed data for all the traits of 18 high sucrose containing sugarcane clones were assessed for statistical analysis viz., analysis of variance, genotypic and phenotypic coefficient of variance, heritability, genetic advance as per cent of mean, correlation coefficient analysis and path coefficient analysis. The analysis of variance revealed highly significant differences among the clones for fourteen traits and significant for rest traits viz., germination % at 45 DAP, plant height at 150 days, single cane weight and purity % at 10 month stage. Variability studies showed high estimates of GCV and PCV for traits viz., length of aerial root and dry weight of aerial roots. In present set of materials high heritability with high genetic advance as per cent of mean were found in single cane weight and length of aerial root indicating preponderance of additive gene effect. Traits namely plant height at 150, 240 & 360 days, single cane weight, brix % at 10 & 12 month stage, pol % at 10 & 12 month stage, showed significant positive correlation and number of aerial roots/ node had significant negative correlation with cane yield. Number of shoot at 120 days, plant height at 150 and 360 days, cane diameter at harvest, number of millable canes, single cane weight, pol % at 10 month stage, brix % at 12 month stage, pol % at 12 month stage, length of aerial root, showed positive direct effect towards cane yield at genotypic level showed importance of these characters for further yield improvement. On the basis of mean performance of cane yield and other productive traits under water logging condition only four clones namely CoX 12137, CoX 12164, CoX 12191 and CoX 12348 were selected. These clones may be utilize for further breeding programme so that recovery and productivity of sugarcane will enhance for water logging condition.

    Study of combining ability and heterosis in sunflower (Helianthus annuus L.)
    (Rajendra Agriculrural University, Pusa (Samastipur), 2015) Kumar, Dhiraj; Singh, U. K.
    The present investigation entitled “Study of combing ability and heterosis in sunflower (Helianthus annuus L.) was undertaken with the objective of identifying good general combiner and to assess the magnitude of heterosis for yield and yield component traits. Altogether 32 hybrids were made from crosses of four cytoplasmic male sterile lines and eight diverse testers in a line×tester matting design. These were evaluated during rabi 2014-2015 at TCA, Dholi, Farm of Rajendra Agricultural University, Bihar, Pusa Samastipur in randomised block design with three replication. The parents and their hybrids were evaluated for 11 characters viz., days to 50 per cent flowering, Plant height, days to maturity, biological yield, head diameter, harvest index, 100 seed weight, volume weight, seed yield per plant, seed filling per cent and oil content. The grand mean of hybrids were significantly superior in the desirable direction compared to parental mean for each character under study. The highest mean performance was recorded in hybrid DSFH-4 for seed yield, DSFH-30 for head diameter and volume weight, DSFH-19 for 100 seed weight, DSFH-14 for seed filling per cent, and DSFH-31 for oil content. Both gca and sca variance differ significantly for all the characters. The magnitude of non-additive gene action was higher than the corresponding additive gene action for all the characters in hybrid. In female parent CMS-SS-502B, CMS-17B came out to be good general combiner for most of the yield and yield contributing traits. CMS-SS-502B was found to be good general combiner for head diameter, 100 seed weight, volume weight, seed yield per plant and seed filling per cent. Likewise CMS-17B was also found to good general combiner for early flowering and maturity, short plant height, 100 seed weight, volume weight and seed filling per cent. Among male parents SS-502-1-1 was good general combiner for biological yield per plant, head diameter, volume weight, seed yield per plant and oil content. Similarly GAUSUF-15 was also good general combiner for early flowering and maturity, short plant height, and 100 seed weight. Significantly favourable specific combining ability effects were observed for number of characters. The hybrid DSFH-4 for biological yield per plant, harvest index, volume weight, seed yield per plant, and seed filling per cent. DSFH-10 for early maturity, biological yield per plant and seed yield per plant. DSFH-6 for biological yield per plant, head diameter and seed yield per plant. DSFH-30 for biological yield per plant, head diameter, volume weight and seed yield per plant. Similarly DSFH-26 for dwarf plant height and volume weight recorded high hybrid performance, high sca and standard heterosis for different characters. The above hybrids were most ideal cross combination displaying consistant high sca effect with high per se performance. The hybrid DSFH-4 showed significant standard heterosis for seed yield per plant, harvest index and seed filling per cent over checks and better parent. DSFH-10 exhibited significant standard heterosis for seed yield per plant and seed filling per cent. Similarly DSFH-6 recorded significant heterosis for seed yield per plant, biological yield per plant, head diameter and seed filling per cent over check and better parents. DSFH-26 showed significant highest standard heterosis for seed yield per plant. It also showed significant heterosis for seed filling per cent and dwarf plant height over checks and better parent. This hybrid had proved to be best for yield over checks and better parent followed by DSFH-4 and DSFH-6.

Based on positive and significant GCA effects along with high per se performance NDM-09-18, SML-668, HUM-12, HUM-6 and IPM-02-14 were identified as a best general combiner for yield. These parental lines may be used in hybridization programme to have the superior cross combinations for yieid. Based on per se performance, SCA and standard heterosis among all crosses, only one cross namely HUM-12 x TMB-37 was found common for seven yield and yield attributing traits except number of root-nodules per plant, seeds per pod, pod length and plant height and other cross namely HUM-6 x SML-668 also found common for five traits Viz. days to 50% flowering, number of root nodules per plant, biological yield per plant, harvest index and seed yield per plant. These two crosses may be exploited in Mungbean improvement programme to enhance the yield.

    Comparative Assessment of Genetic Diversity in Aerobic Rice.
    (Rajendra Agricultural University, Pusa (Samastipur), 2015) Chandra, Khushboo; Nilanjaya
    A study was conducted on 25 rice genotypes at Rain out Shelter (aerobic condition) and Rice Breeding section (normal condition), RAU, Pusa, Samastipur, Bihar during kharif 14 for “COMPARATIVE ASSESSSMENT OF GENETIC DIVERSITY IN AEROBIC RICE” and was laid out in Randomized Block Design with three replications based on variability, heritability (broad sense), genetic advance, character association, path analysis and genetic divergence for 15 morpho-physiological characters. Analysis of variance revealed highly significant variation among all the 25 genotypes of rice for all the 15 characters under aerobic and normal condition. The characters, namely 1000 grain weight, relative water content, maximum root length, flag leaf area, peroxidise activity in leaves and grain yield per plot had showed high heritability coupled with high genetic advance as per cent of mean under aerobic and normal conditions. Correlation studies indicated that at genotypic and phenotypic level for plant height, panicle length, spikelet per panicle, tillers per plant, 1000 grain weight, relative water content, maximum root length, flag leaf area, harvest index under aerobic condition, whereas, under normal condition, days to physiological maturity showed positive and significant association with grain yield per plant. Path analysis revealed that traits like days to fifty percent flowering, no. of spikelet per panicle, no. of tillers per plant and maximum root length had positive direct effect whereas, harvest index had both direct and indirect effect on grain yield per plot at genotypic level and at phenotypic level traits like days to fifty percent flowering had positive direct effect and days to physiological maturity, plant height, panicle length,1000 grain weight, relative water content, proline accumulation in leaves, peroxidase activity, no. of tillers per plant and maximum root length had positive indirect effect. No. of tillers per plant and 1000 grain weight had both direct and indirect effect on grain yield per plot at genotypic level and at phenotypic level traits like proline accumulation in leaves had positive direct effect but days to physiological maturity, plant height, panicle length,1000 grain weight, relative water content, peroxidase activity, no. of tillers per plant, maximum root length, no. of spikelet per panicle, flag leaf area and chlorophyll content had positive indirect effect on grain yield per plot under normal condition. On basis of inter cluster distances, cluster mean and mean performance, genotypes viz., RAU1417-2-1-5-7-7 and Vandana (Check) from cluster I &RAU1417-2-1-5-7-7 from cluster VI selected for earliness were identified as promising parents for their further utilization in hybridization programme under aerobic and normal condition. Under aerobic condition, the genotypes viz., RAU1417-2-1-5-7-7 exhibited superiority for proline accumulation in leaves. The genotypes viz., RAU1397-18-3-7-9-4-7from cluster III were selected for traits like panicle length, spikelets per panicle, tillers per plant, RWC in flag leaf, maximum root length, flag leaf area, chlorophyll content and grain yield per plot in normal condition.
