Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Genetic analysis of spike morphology and grain yield component traits in Triticum aestivum L. em Thell
    (CCSHAU, 2011) Pawan Kumar; Yadav, Ramesh Kumar
    The present investigation comprising six generation (Parents, F1, F2, BC1 and BC2) of five crosses wheat viz. HJP81 x Rm-Ts17, HS27 x PBW502, HJP81 x PBW502, HS67 x PBW502, HG2 x HD2009M was conducted for estimating the gene effects for the spike morphology and yield component traits under two successive growing seasons (2008-09 and 2009-10) for fifteen spike morphological and yield component traits at the experimental area of the Department of Genetics & Plant Breeding, CCS Haryana Agricultural University, Hisar, India. Generation mean analysis revealed significant differences for all traits where the A, B, C and D individual scales were also significant for most of the characters indicating thereby the presence of non-allelic interactions. In some of the cases, the non-significance of chi-square value indicated the fitness for additive-dominance model. Additive component was significant for most of the characters and even as preponderant in magnitude over the dominance component. Either all or any of the three types of epistatic interactions (i, j and 1) were significant for most of the cases and generally it is the “i" type of interaction which is more frequently prevailing for most of the traits studied over the crosses. However, the magnitude and direction of estimates changed for the cross and the seasons. Additive x additive type of interaction with overdominance was recorded for peduncle length in cross-II, where the chance of transgressive segregates was high. Duplicate type of interaction was apparent for plant height, peduncle length, spike length, spike compactness, spike biomass, 100 kernel weight, grain: spike biomass ratio and grain yield per plant. Complementary type of interaction was recorded for peduncle length, spike biomass, 100 kernel weights and days to heading. Significant heterosis was observed for plant height, peduncle length, spike length, grain: spike biomass ratio, grain yield per plant and days to heading. The magnitude and direction of heterosis was varying from cross to cross over both seasons, however, the inbreeding depression was also indicated as positive and significant in most cases. The potence ratio in F1 and F2 depicted the partial and over dominance was shown by all the traits under study. Genetic variability was estimated by GCV and PCV indicated maximum diversity for the cross-I followed by cross-IV, II, III and V. The genetic similarity coefficient analysis showed that extensive genetic diversity (from 26% to 93%) was present among parental genotypes. In cross-HJP81 x Rm-Ts17 the dendrogram constructed and clustered in six major groups. The hierarchical cluster analysis for cross-IV revealed that the F2 populations along with their parents were mainly divided into two major clusters and eight subgroups. Similar finding were revealed by PCA analysis. The F2 population SSR maker data for C-I and C-IV were subjected for the QTL analysis by WinQTL-Cartographer. Five QTL were detected for spike biomass at map positions, 88.1 (1A), 33.2(1B), 111.7(2D), 46.6(5A) and 97.8(5A) by SSR marker BARC263, BARC187, WMC601, XGWM443 and WMC475 respectively. Four QTL were detected for kernel weight per spike at map positions, 100.8 (1A), 45.9 (1B), 45.1 (5A), 103.0 (5A) by SSR marker WMC254, WMC416, XGWM443 and WMC110. These QTLs may be used for further improvement of the traits they represent.

    Studies on variability in sclerotinia sclerotiorum (Lib.) de bary causing stem rot in Indian mustard
    (CCSHAU, 2013) Pawan Kumar; Rathi, A.S.
    The stem rot disease caused by Sclerotinia sclerotiorum (Lib.) de Bary is the most serious fungal disease and causes maximum damage in Indian mustard (Brassica juncea). The present investigation on cultural, morphological, pathogenic and genetic variability was carried out with fourteen isolates of S. sclerotiorum collected from mustard growing areas of the country. All the isolates exhibited variations in their colony colour, type of growth and mycelial growth. HSR, FTH, SRS and DBW isolates showed dirty white colony colour, while rest of the isolates showed whitish colony colour. The variation in type of growth was also observed as BWL, MHR and BHR isolates showed fluffy and regular type of growth; ALW and JLN isolates showed fluffy but irregular growth, while rest of the isolates showed sparse and regular type of mycelial growth. All isolates showed significant differences in mycelial growth up to 72 hours of incubation, while non- gnificant differences were observed after 96 hours of incubation among the isolates. Significant variations were observed in number of sclerotia formation, size and pattern of sclerotia formation among the isolates after 10 days of incubation. Sufficient variability was also observed for number of apothecia per sclerotium. Isolates were also found to vary in their per cent disease intensity and significant host × pathogen interaction on different rapeseed-mustard genotypes under screen house and field conditions. HSR isolate was the most pathogenic with mean disease intensity of 53.1 and 60.8% under field and screen house conditions, respectively, while ALW was the least pathogenic isolate with disease intensity of less than 30% under both the conditions. Some isolates showed moderately resistant reaction on one genotype while, susceptible to highly susceptible reaction on rest of the genotypes. Some of the isolates could not be clearly differentiated pathogenically; however, they showed variable reactions on these genotypes. The variation was observed for stem breaking of different genotypes and formation of varying numbers of sclerotia after inoculation of S. sclerotiorum isolates under field conditions. The ITS (Internal transcribed spacer) analysis differentiated the fourteen isolates into two major clusters at similarity coefficient of 0.38. Cluster A was constituted by only one isolate ALW and Cluster B was a large group containing 13 isolates. Cluster B was further divided into two groups C and D which occupied nine and four isolates, respectively.

    Studies on the effect of drying methods and packing material on the shelf life of aonla powder (Emblica officinalis G.)
    (CCSHAU, 2011) Pawan Kumar; Surinder Kumar
    The present investigation was carried out in the Fruit Processing Laboratory of Department of Horticulture, CCS, Haryana Agricultural University, Hisar. Powder of aonla fruits was prepared by blanching of aonla fruits in boiling water (98±2˚C) with five different concentration of KMS viz. 0ppm, 250ppm, 500ppm, 750ppm and 1000ppm KMS. After blanching the seeds were removed from the fruits and fruit pulp was dried in oven tray drier at (60˚C) and in solar tunnel drier. After dehydration, product was grinded into powder and packed in aluminium laminated bags and in polythene bags. Packed samples of powder were stored at ambient temperature with objective to study the effect of drying methods and packing material on quality of aonla powder during storage. During studies of drying of aonla pulp it was observed that the rate of moisture loss was fast in oven tray drier as compared to solar tunnel drier at each interval of time period. Moisture content of dehydrated product was recorded (9.04%) in solar tunnel dried and (8.21%) moisture content in oven tray dried fruit pulp. Maximum recovery percentage (10.37%) of aonla powder was recorded from fruits treated with 1000ppm KMS as compared to minimum (10.12%) recovery percentage from fruits treated with 0ppm KMS irrespective of drying methods. Loss of ascorbic acid content and acidity content was observed during blanching and drying. Maximum retention of ascorbic acid content (514.00 mg/100g) was recorded from fruits blanched with 1000ppm KMS. Maximum reduction in acidity content was recorded from 2.11% to 1.46% in fruits blanched with 0ppm KMS. During storage of aonla powder ascorbic acid, acidity, total sugars and reducing sugars content were decreased with increase in storage period whereas non-enzymatic browning and non reducing sugars increased with increase in storage period. During present investigation, it was also observed that fruits treated with 1000ppm KMS had retained maximum ascorbic acid and acidity content and recorded minimum non-enzymatic browning in both drying methods during storage, whereas fruits treated with 0ppm KMS had retained minimum ascorbic acid and acidity content and had maximum browning during storage. Sugars content were at par with each other with increase in concentration of KMS in both the drying methods. Maximum total sugars, reducing sugars and nonreducing sugars content were recorded in oven tray dried aonla powder during storage.

    (CCSHAU, 2012) Pawan Kumar; Bhatia, A.K.
    The experiment entitled“Effect of seed size, spacing and nitrogen on seedpotato production cv. Kufri Bahar.” was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during winter season of 2009-10. The experiment comprising of three seed size (25-50 g, >50-75 g and >75-100 g), three plant spacing (60x10, 60x15 and 60x20 cm) and two nitrogen level (100 and 125 N kg/ha) was laid out in a randomized block design with three replications keeping net plot size 3.6x3.0 m. Ten competitive plants were selected randomly from each experimental treatment to record data on various parameters, which were influenced significantly by different seed size, plant spacing and nitrogen levels. The per cent plant emergence, plant height, leaves/stem, leaf area index, number of tubers up to 25 g, >25-50 g and >50-75 g grade, total numberof tuber, weight of tuber >25-50 g and >50-75 g grade were statistically higher with seed size >75-100 g tubers. However, the value for number of stems per hill, leaves weight per hill, stem weightand weight of foliage, number of tubers per plot >75 g grade, weight of tubers up to 25 and >75 g and total tuber yield was maximum with >50-75 g seed size tubers. Different plant spacing exhibited significant difference for growth and yield parameters. The maximum value for plant height, stem/hill, leaves/stem, leaf area index , leaves weight, stem weight, weight of foliage, number of tubers >50-75 g and >75 g grade, total number of tubers, weight of tubers up to 25 g, >25-50 g >50-75 g, >75 g grade and total tuber yield were maximum with 60x20 cm plant spacing. However, per cent plant emergencewas found maximum with plant spacing 60x15 cm and number of tubers up to 25 g and >25-50 g grade tubers per plot were found maximum with plant closest spacing of 60x10 cm. Effect of nitrogen level showed remarkable variation for growth and yield parameters except per cent plant emergence. Significantly highest value was registered for plant height, stem/hill, leaves/stem, leaf area index, leaves weight, stem weight, weight of foliage, numberof tubers up to 25 g, >25-50 g, >50-75 g and >75 g, total number of tubers, weight of tubers up to 25 g, >25-50 g >50-75 g and >75 g grade, total tuber yield with nitrogen 125 kg/ha. However, plant emergence found maximum with nitrogen 100 kg /ha. Kufri Bahar produced highest total tuber yield 437.14 q/ha when >50-75 g seed size tubers were planted at a spacing 60x20 cm and nitrogen level 125 kg/ha which was followed by seed size >75-100 g, plant spacing 60x15 cm and nitrogen level 100 kg/ha.
