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.

    Effect of plant growth regulators and flower emasculation on fruit set and fruit quality of Kinnow mandarin
    (CCSHAU, 2018) Kumatkar, Raghunath Bhimrao; SHARMA, SUNEEL
    The present experiment was conducted to study the Effect of plant growth regulators and flower emasculation on fruit set and fruit quality of Kinnow mandarin at Experimental orchard of the Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2016 and 2017. Maximum (70.42% and 73.21%) initial fruit set was observed with foliar application of GA3 10 ppm sprayed at full bloom stage and highest fruit retention (19.22 and 19.79%) was recorded with the application of 2, 4-D 15 ppm during 2016 and 2017. The post-bloom stage appeared most suitable for application of PGR‟s for higher final fruit retention. The highest increase in fruit length, diameter and weight was exhibited with NAA 10 ppm applied at post bloom stage. Higher fruit length/diameter ratio was displayed when the plants were sprayed with GA3 5 ppm. The minimum (3.45 and 3.40 mm) peel thickness was observed in control. Maximum (49.66 and 49.77%) juice content was recorded with the application of NAA 10 ppm. The post-bloom stage appeared significantly most suitable for application of PGR‟s. The minimum (15.28 and 11.92) number of total seeds/fruit, minimum (11.77 and 12.37) number of healthy seeds/fruit and maximum (3.51and 3.55) number of aborted seeds/fruit was recorded with the application of GA3 10 ppm and the post-bloom stage appeared to be most suitable for the application of PGR‟s. The seed length, breadth and weight were observed minimum in treatment of GA3 10 ppm and post-bloom stage appeared most suitable. Application of NAA 10 ppm treatment had recorded significantly highest TSS value (9.92 and 9.84°Brix), lower acidity (0.87 and 0.85%) and highest (32.04 mg and 31.59 mg) increase in ascorbic acid content. The maximum (11.75 and 11.86) TSS/acid ratio was observed under 10 ppm NAA treatment at post bloom stage. Initial fruit set (66.68% and 69.46%), final fruit retention (18.39% and 19.68%), fruit length, diameter and weight were recorded higher in flowers without emasculation followed by application of GA3 10 ppm in both the years. The maximum fruit length diameter ratio was accounted in flower without emasculation followed by application of GA3 5 ppm. Minimum (9.35 and 9.40) number of total seeds, number (7.21 and 6.94) of healthy seeds and maximum number of aborted seeds per fruit (3.14 and 3.21) recorded from application of GA3 10 ppm with flower emasculation during 2016 and 2017. The minimum seed length, breadth and weight were recorded in fruits obtained from flower emasculation followed by the application of GA3 10 ppm. Maximum juice content (49.05%) was observed in flowers without emasculation followed by the application of GA3 5 ppm. In treatment of flowers without emasculation coupled with application of GA3 5 ppm recorded maximum TSS, lowest acidity, maximum TSS/acid ratio and maximum ascorbic acid content.

    Studies on floral biology and breeding behaviour of sweet orange (Citrus sinensis (L.) Osbeck.)
    (CCSHAU, 2014) Kumatkar, Raghunath Bhimrao; Godara, A. K.
    The present experiment was conducted to study the floral biology and breeding behaviour of sweet orange cultivars viz., Pineapple, Blood Red, Jaffa and Mosambi. In sweet orange flowering takes place only once in year i.e. February–March under North Indian conditions. The duration of floral bud development was 19-23 days in different cultivars Jaffa was earliest to start flowering. The duration of flowering was 20-23 days in the cultivars. These cultivars came to full bloom in last week of February to first week of March. Two type of inflorescence were observed i.e. leafy and leafless. The flowers were borne on current season’s growth in the axils of leaves either solitary or in cymes of three to eight. Flower structure observed in sweet orange with five sepals, five petals and twenty stamens with superior ovary. The maximum opening of flowers and dehiscence of anthers took place in morning hours (10.00 A.M. to 12.00 noon) in all the cultivars. Stigma became receptive just after anthesis and remained receptive till 72 hours of pollination in all the cultivars. The maximum receptivity was recorded on the day of anthesis. The highest fruit set was recorded in cultivar Jaffa under open pollination (32.84%) followed by self pollination (29.81%) and lowest fruit set was recorded in cv. Blood Red.
