Bihar Agricultural University, Sabour

Bihar Agricultural University, Sabour established on 5th August, 2010 is a basic and strategic institution supporting more than 500 researchers and educationist towards imparting education at graduate and post graduate level, conducting basic, strategic, applied and adaptive research activities, ensuring effective transfer of technologies and capacity building of farmers and extension personnel. The university has 6 colleges (5 Agriculture and 1 Horticulture) and 12 research stations spread in 3 agro-ecological zones of Bihar. The University also has 21 KVKS established in 20 of the 25 districts falling under the jurisdiction of the University. The degree programmes of the university and its colleges have been accredited by ICAR in 2015-16. The university is also an ISO 9000:2008 certified organisation with International standard operating protocols for maintaining highest standards in teaching, research, extension and training.VisionThe Bihar Agricultural University was established with the objective of improving quality of life of people of state especially famers constituting more than two third of the population. Having set ultimate goal of benefitting society at large, the university intends to achieve it by imparting word-class need based agricultural education, research, extension and public service.

    Rapid multiplication of banana cv. ‘Grand Naine’ through tissue culture
    (Department of Horticulture (Fruit & Fruit Technology), BAU, Sabour, 2016-07) Kumar, Ravi; Ahmad, M. Feza
    Banana is generally propagated vegetatively through suckers, which grow from lateral buds originating from corms and suckers. Suckers are used for production of individual plants. In some instances, complete or separated corms with one or several buds may be used. This process is very slow as the rate of multiplication of suckers through conventional vegetative means has been found to express several negative impacts which include transmission of diseases, low production and poor preservation of original plant genetic material. Further one banana plant produces only five to ten suckers in a year depending upon the variety and grow more slowly and produce smaller bunches. Quality planting material is the key for successful production of banana and tissue culture is an excellent option for producing low cost quality planting material. The rapid proliferation obtained in tissue culture allows nurserymen to meet an unexpected demand for a particular variety. Keeping in view the importance of tissue culture technology in banana an experiment was carried out on “Rapid multiplication of banana cv. ‘Grand Naine’ through tissue culture”. One of the most commonly encountered problems in in vitro culture establishment is the contamination. The efficiency of sterilizing agents was evaluated in terms of maximum aseptic explants sprout. The contamination significantly decreased with increase in concentration of sterilants and their time of exposure. MS media supplemented with 2,4-D 2.0 mg /l+ NAA 0.1 mg/l was found most effective for callus formation. Addition of cytokinin alone or in combination with auxins was found essential during shoot proliferation and multiplication. BAP 3.0 mg l-1 + NAA 1.0 mg l-1 was found most effective with regard to number of days (22.2) required for shoot induction and length of shoots ( 7.0 cm) where as maximum number of shoots (4.8) was achieved with BAP 4.0 mg l-1 + IAA 0.1 mg l-1. Half strength MS media with IBA 1.5 mg l-1 was found significantly higher over all other auxin treatments for various rooting parameters. Grand Naine plantlets obtained through in vitro propagation exhibited highest 80 percent survival in coco peat during acclimatization.

    Heterosis and combining ability analysis for productivity and its related traits in round brinjal (Solanum melongena L.)
    (Department of Horticulture (Vegetable and Floriculture), BAU, Sabour, 2016-07) Kumar, Ravi; Kumar, Randhir
    The experiment entitled “Heterosis and combining ability analysis for productivity and its related traits in round brinjal (Solanum melongena L.)” was undertaken with the objectives (1)To estimate the magnitude of heterosis (2)To study the effect of gca of the parents and sca of F1s (3)To evaluate the incidence of bacterial wilt and fruit borer of high yielding brinjal. The material of genotype consisted of six diverse parents (SBRB-6/12, SBRB-1/12, KS-224, SBRB-2/12, Swarna Mani and SBRB-3/12) and their 30 F1s obtained by crossing in diallel fashion (including reciprocals) in randomized complete block design in three replications having each experimental unit of single row with spacing of 60x60 cm at Vegetable Research Farm,Department of Horticulture (Vegetable and Floriculture) Bihar Agricultural College,Bihar Agricultural University, Sabour, Bhagalpur during Rabi Season 2012-2013. Observations were recorded on the five plants from each plot maintained for eleven traits viz; Days to first flowering, Days to 50% flowering, Fruit length (cm), Fruit diameter (cm), Average fruit weight (g), Plant height (cm), No. of Primary branches, Number of fruits per plant, Fruit yield per plant(kg) and Incidence of bacterial wilt & fruit borer infestation. Analysis of variance due to genotypes, parents and hybrids were almost highly significantfor all the eleven characters except no. of primary branches and fruit borer incidence due to parents. However, for parents vs. hybrid only five characters viz.; fruit length, no. of primary branches, plant height and per cent incidence of bacterial wilt found highly significant. The crosses namely SBRB-3/12 x SBRB-2/12(88.79), SBRB-6/12 x SBRB-3/12(69.03) and KS-224 x Swarna Mani(66.08) were the best heterotic combination over standard parent Swarna Mani.The variances due to gcaand scawere significant for almost character except days to 50% flowering, fruit diameter and no. of primary branches per plant and sca were significant for all the eleven characters studied. Significant gca and sca were observed for all traits which also evidenced close association with per se performance. SBRB 3/12 was found best combiner for fruit yield per plant and lower incidence for bacterial wilt. Thus heterosis breeding method may be more rewarding for improvement in brinjal
