Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    Genetic characterization and selection parameters for yield, morpho-physiological and quality traits in land races, japonicas and new plant type rices
    (CSK Himachal Pradesh Krishi Vishavavidyalaya, Palampur, 2006) KUMAR, VIJAY; Katoch, P.C.
    To study the variability, associations among traits, selection indices and diversity among 57 rice genotypes comprising of 21 land races, 18 new plant types and 15 japonicas alongwith three checks China 988, RP 2421 and Naggar Dhan, the experiment was conducting during two consecutive years i.e. Kharif 2004 and 2005 at RWRC, Malan and experimental farm of the Department of Plant Breeding & Genetics, CSK HPKV, Palampur. The experiment was laid out in compact family block design with three families (land races, new plant types and japonicas) and three replications. Analysis of variance revealed significant variation for all the characters studied during the years and combined over years at both locations within and among families. High heritability coupled with high genetic advance was observed for harvest index at Palampur in land races; for total tillers per plant, effective tillers per plant, spikelets per panicle and grains per panicle at Malan in new plant types; and for spikelets per panicle and grains per panicle at both the locations in japonicas. Heritability estimates were also high for most of the quality traits. At phenotypic level, grain yield per plant exhibited positive and significant associations with total tillers per plant, effective tillers per plant, biological yield per plant and harvest index in land races; with plant height, biological yield per plant and harvest index in new plant types; and with spikelets per panicle, grains per panicle, biological yield per plant and harvest index in japonicas at both the locations. Genotypic correlation coefficients were higher than the phenotypic ones. Selection indices revealed that the combinations of four characters viz., panicle length, effective tillers per plant, spikelet fertility and biological yield per plant in land races; grains per panicle and 1000-grain weight in new plant types; and panicle length and spikelets per panicle in japonicas were more efficient than direct selection for yield. D2- statistics grouped 57 genotypes in to 13 diverse clusters in 1st year, 2nd year and combined over years at Malan, whereas 16, 9 and 10 diverse clusters in 1st year, 2nd year and combined over years, respectively at Palampur. Molecular markers (RAPD) grouped the genotypes in eight different clusters. Clustering pattern did not necessarily follow their geographic or location distribution. The genotypes present in different groups (land races, new plant type and japonica type) were generally present in separate clusters with a few cases of overlapping with both the methods. Days to flowering, days to maturity, grain length and grain width contributed most towards divergence at both the locations. Variation for morphological descriptors was present only in land races and local japonicas. High amount of variation was present for iron content in the grains among land races and new plant types ranging from 0.53 μg/g to 31.27 μg/g and 0.16 μg/g to 48.79 μg/g, respectively, while variation was less in case of japonicas. Variation for zinc content present in grains was in general low.

    GENETIC ANALYSIS OF MORPHOLOGICAL, BIOCHEMICAL AND MOLECULAR TRAITS OF SOME NOVELTY RICES OF HIMACHAL PRADESH
    (CSK Himachal Pradesh Krishi Vishavavidyalaya, Palampur, 2008) SOOD, RITU; Kaushik, R.P.
    “Genetic analysis of morphological, biochemical and molecular traits of some novelty rices of Himachal Pradesh” was carried out by using 17 red pericarp rices, 19 purple leaved rices and 11 quality rices along with three checks in Randomized Block Design at Rice and Wheat Research Centre, Malan (Kangra). The data was analyzed using statistical procedures. Based on overall performance, Achhoo Baldhar, IC3131159, Kijun and Tiyun among red pericarp rices; RLC-3, Lal Nakanda-41, R-575 and Purple Baldhar among purple leaved rices and LC99-5B, IC3131155 and Rajpur Basmati among quality rices were found to be promising genotypes for further exploitation. Tiyun had high sugar (10.4 mg) and high protein content (14.0%). R-575 had high 1000-grain weight (32.1 g). IC3131166 and Rajpur Basmati had long slender grains, high elongation after cooking and high brown rice protein. Grain yield had significant positive correlation with grains per panicle, plant height and spikelets per panicle thus direct selection for those characters will be effective. Based on path coefficient analysis tillers per plant, panicle length, grains per panicle and 1000-grain weight had high positive direct effects on yield. Molecular analysis based on RAPD markers grouped 41 genotypes into cluster I, 25 of these were grouped into cluster II of ISSR and 33 in cluster I of D2-statistics (combined over years). This suggested similarity in clustering pattern based on these techniques. Grouping of majority of the genotypes into one cluster suggested affinity among the genotypes indicating their origin in same geographical area. Grouping based on pooling two types of markers revealed that majority of the red pericarp rices and purple leaved rices grouped into same cluster. Tremendous variation in anthocyanin pigmentation of different plant parts was present in all red, purple and quality rices. Among check variation was present only in case of size of auricle. Auricles were absent in Achhoo and Achhoo Baldhar. Varieties namely, China Purple, HPR-1194, HPR-2089, HPR-2178, Palampur Purple and Nagrota Purple had dark purple leaf blade, purple auricle, purple stigma and purple apiculus. Achhoo Baldhar had long grains with dark red pericarp, whereas IC3131171 and IC3131159 had light red pericarp and long grains.
