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.

    Characterization for yield and quality traits under aerobic and transplanted condition in rice (Oryza sativa L.)
    (CCSHAU, Hisar, 2021-09) Bhawana; Rakesh Kumar
    The present experiment was carried out at Rice Research Station, Kaul, CCS Haryana Agricultural University Hisar, during Kharif, 2020 to estimate co-efficient of variability, heritability, genetic advance as percent of mean, character association, path co-efficient analysis and genetic divergence for yield and quality traits grown under aerobic and transplanted conditions. A total of 48 genotypes (24 basmati and 24 non-basmati genotypes) were grown in single row (5m long) of each genotype in each replication using randomized block design with spacing 20 x15 cm between rows and plants respectively. Observations were recorded on five randomly selected plants for each genotype on 21 morphological and quality traits. Mean sum of squares due to genotypes were highly significant for all the traits indicating the presence of sufficient variability under both the conditions. Narrow range of GCV and PCV indicated major role of genetic factors in expression of traits than environmental factors. In basmati genotypes, high heritability coupled with high genetic advance as per cent of mean was observed for grain yield/plant, plant height, number of grains/panicle and root dry weight under both conditions. While in non-basmati genotypes, grain yield/plant had high heritability coupled with high genetic advance as percent of mean revealed the importance of additive gene action in expression of the trait. Grain yield/plant showed significant positive correlation with number of tillers/plant, test weight, harvest index % and kernel breadth under both conditions for basmati genotypes, whereas in non-basmati genotypes grain yield/plant exhibited significant positive correlation with biological yield/plant followed by harvest index %, plant height, test weight , number of grains/panicle, number of tillers/plant, root fresh weight and root volume under both conditions suggesting that for improving grain yield direct selection of genotypes for these traits will be more fruitful. Path analysis revealed that biological yield/plant and harvest index % exhibited major positive direct effect on grain yield under both conditions for basmati genotypes whereas, in non-basmati genotypes kernel length followed by number of grains/panicle, days to 50% flowering and biological yield/plant, harvest index % and root volume exerted high positive direct effect on grain yield. Group constellation of genotypes under both the conditions (aerobic and transplanted) did not follow their geographical distribution. On the basis of grain yield HKR 15-455, HKR 16-459, Pusa 1557-06-08-126-162-156 and HKR 15-488 were identified superior than check Haryana Basmati -2 whereas HKR 15-488 and HKR 16-459 were identified as suitable genotypes for quality parameters over check Taraori Basmati. Genotypes, IR14L521, HKR 16-35 and NVSR 2107 were observed suitable under both aerobic and transplanted conditions as these genotypes performed significantly higher than the check HKR 47 and HKR 48 respectively.
