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.

    Studies on drought tolerance, genetic divergence and character association in mothbean [Vigna aconitifolia (Jacq.) Marechal]
    (CCSHAU, 2006) Ranjit Singh; Jaivir Singh
    The objectives of the present study were to study the physiological basis of drought tolerance in mothbean, to determine the yield component under dry land conditions, to identify diverse and elite genotypes and suggesting breeding method for further improvement in mothbean. The experiment was conducted during Kharif, 2002 at research area, CCS Haryana Agricultural University, Hisar. In the present investigation, 43 genotypes of mothbean were grown in randomized block design with four replication accommodating spacing 30× 10 cm. Observation on 5 competitive plants for recording of data on different physiological traits and yield components were taken. Substantial amount of coefficient of variation was observed for all the traits/characters under study. A wide range for different traits/characters were also observed. The higher phenotypic coefficient of variation over genotypic coefficient of variation showed in almost all the traits/characters. The estimation of -iv- -4- high heritability with high genetic advance was recorded for pod per plant in both the environments while in case of physiological traits it was observed for water retention. On the basis of D2-value 43 genotypes were grouped into nine cluster in E1 and eight in E2. There was no association between clustering pattern and ecogeographical distribution of the genotypes. RMO 257, RMO 40 and Jwala are released varieties were clustered into same cluster in both the environment. In almost all the cases phenotypic correlation coefficient was more than genotypic correlation coefficient. Correlation studied revealed significant positive association of seed yield per plot with 100-seed weight, seed yield per plant, pod per plant, pod per cluster in both environment. Path analysis revealed that maximum direct effect on seed yield per plant was through yield per plot and pod per cluster in E1 and E2 respectively. An examination of the trend of correlation revealed that the yield per plot, pod per plant, pod per cluster, pod length and 100-seed weight were the important characters that exerted the greatest influence both directly and indirectly upon seed yield per plant. These characters were important components in almost all correlations that involved seed yield. On basis of membrane stability the best performing genotypes/varieties were IC 329051, IC 311448, IC 329044 and RMO 257. On basis of the canopy temperature depression the best performing genotypes/varieties were IC 329051, IC 311448, IC 329044, IC 329090, IC 370471, IC 329037, IC 311427 and RMO 40. RMO 40 and RMO 257 were observed as best performer for high water retention.
