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.

    Evaluation of seed vigour parameters for heat tolerance in bread wheat
    (CCSHAU, 2014) Arun Kumar; Dahiya, O.S.
    Wheat (Triticum aestivum L.) is a widely adapted crop. It is grown from temperate, irrigated to dry and high-rain-fall areas and from warm, humid to dry, cold environments. The genetic purity, physical purity, viability, vigour and uniform seed size are the most important parameters to determine the quality of seed. High seed germination and vigour are pre- requisites for the success of stand establishment of crop plants. Generally stress (moisture/heat) has deleterious effect on germination and vigour of crop.The present investigation was carried out at the department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar. The material comprised of six each heat tolerant and susceptible varieties which were sown on two date i.e. normal (19th, 20th November) and late sown (19th, 20th December). The observations were recorded at grain filling stage (heading to maturity). Heat tolerant varieties had performed better at different stages of seed development in comparison to susceptible. Heat tolerant varieties were found significantly higher for seed weight, seed moisture content, germination, seedling length, vigour index-I & II, seedling dry weight and than susceptible varieties under normal and late sowing condition in both the year. Heat tolerant varieties were recorded significantly lower for days to heading, physiological and harvestable maturity. It means heat tolerant varieties mature earlier than susceptible. Commonly varieties had performed better for all characters studied in normal than late sowing at all stages of seed development. Heat tolerant varieties recorded higher for membrane Thermostability and lower for chlorophyll fluorescence. This might be effect of heat stress during seed development. Both vigour index-I and II were significantly and negatively correlated with maximum, minimum and difference of temperature but positively with sunshine hour and relative humidity in both the years of data recording. It means that as optimum temperature for cultivation of wheat is increasing then vigour of the seed will be decreases. For normal as well as late sown heat tolerant varieties having more DHA, peroxidase, catalase and superoxide dismutase activity at all stages than heat susceptible. All stress enzyme activity was higher in late than normal sowing which was in concurrence with high temperature during seed development. Number of grains per spike (average of five plants), number of grains per spike and grain yield per plant was higher for normal sown than late sown in both the year. Varieties have performed better in second year than in first year. Heat tolerant has performed better than susceptible for almost all agronomic traits. Based on both the tests it can infer that there was better relative storability of the variety for normal than late sowing over the years at all stages of storage.

    Physiological and biochemical changes during storage and seed priming in pearl millet
    (CCSHAU, 2013) Gupta, Ankush; Punia, R.C
    The present investigation was carried out on seeds of 2 pearl millet hybrids viz .,HBB197 and HHB223 along with their parental A, B and R lines viz ., A- ICMA97111 andI CMA94555, B-ICMB97111 and ICMB94555, R- HBL-11 with the objectives to study the physiological and biochemical changes associated with seed deterioration, to study the effect of different containers and storage conditions on seed quality and to study the effect of various seed priming treatments on seed quality. In the first experiment seven genotypes with 8% moisture content were packed in poly set bin, polythene bag and cloth bag and stored under ambient and cold storage condition (20C). Among the storage condition and packaging material tested,the seeds preserved under cold storage and packed in polyset bin and polythene bag recorded higher germination, seedling vigour index,seedling dry weight,seedling establishment and other quality parameters with less qualitative loss in comparison to those seeds stored underambient condition through out the storage period of 24 month , Activity of all the anti-ox idant enzymes viz. , peroxidase , catalase and dehydrogenase activity decreased while EG and FFA increased with storage period butminimum deterioration was occurin the seeds preserved in polyset binand polythene bagunder cold storage condition . Vigour of all the genotypes also decreasedwith storagepriod. Among all the, genotypes HHB197 was observed highly vigorous and proved goodstorer .The interaction effect of genotype HHB197 packed in vapour proofcontainer ( polysetbin and polythene bag ) and stored under cold storage is proved to be better in maintaining the seed quality of pearl millet for long rperiod. . In the 2nd experiment, an effort had been made to improve the seed quality with various seed priming treatments (control ,water,GA3 , KNO3 , KH2PO4, thiram andvita vax +cruzer.). Am ong various priming treatments hydration with GA3 (50 ppm) was foundsuperior for enhancing seed quality in all the seven genot ypes of pearl millet followed by,25 mg vitavax +25 mg cruzer tr eatment . The maximum enhancement in germination was observed in fresh lot as compare to one year old seed lot by different priming treatment sand among genotypes, maximum enhancement was observed in genotype HHB223 and minimum in ICMB9 7111.
