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.

    Combining ability and economic heterosis for seed cotton yield and attributing traits in American cotton (Gossypium hirsutum L.)
    (CCSHAU, 2016) Ankit Kumar; Nirania, K.S.
    The present study was undertaken to estimate economic heterosis with the objective of exploring possibilities of its commercial utilization and to study the combining ability effects. The material for the present investigation comprised of Forty American cotton hybrids developed on four female parents (testers) using ten male parents (lines) in line x testers mating design and one standard check (HHH 223).The experimental material was grown at CCS Haryana Agricultural University, Cotton Research Station Sirsa, during Kharif 2014-15 in a randomized block design with three replications. Observations were recorded for eight characters namely, plant height, number of monopods, number of bolls, boll weight, ginning out turn, seed index, lint index and seed cotton yield per plant. The economic heterosis was calculated over standard check HHH 223. Considerable amount of heterosis were recorded for seed cotton yield and other related characters under study. The hybrids H1117 × GS-10, H1117 × HS-180, H1117 × PUSA-1803, H1098 × HS-180 , H1098 × RED 5-7, H1117 × Tamcot SP-23 and H1098 × GS-10 exhibited heterosis of more than 70 per cent and hence warrant their further testing over locations for commercial utilization. The combining ability analysis revealed that additive variance was more than non- additive variance in the expression of all the traits. Among female parents H1117 was the best general combiner. In general, none of the male and female parents was found to posses high gca effects for all the characters under study. However, considering the economic importance of various characters HS- 180, GS-10, PUSA-1803 and RED 5-7 among the male and H1117 among female may be used for future breeding.
