Agriculture University, Kota

The Agriculture University, Kota (AUK) was established on 14th September, 2013 after bifurcation of the Maharana Pratap University of Agriculture & Technology (MPUAT), Udaipur and Swami Keshwanand Rajasthan Agricultural University (SKRAU), Bikaner through promulgation of Act No. 22 of 2013. The University has been created for the agricultural development in South-East and Eastern Rajasthan which is having diversified agriculture situations from rainfed to canal irrigated agriculture. The Agriculture University has its Headquarter at Borkhera Farm, Kota & is located on Kota-Baran National highway-76. Kota district is situated in the South-Eastern part of Rajasthan and comes under Humid South-Eastern Plain Zone (agro climatic zone V). It lies between 23045’ and 26038’ North latitude and 75037’ and 77026’ East longitude. The jurisdiction of AUK is spread over in 6 districts namely Kota, Baran, Bundi, Jhalawar, Karauli and Sawai Madhopur. It accounts for 9.98 % geographical area, 12.67 % total human population, 9.4 % live stock population, 31.59 % forest area and 20.6 % net sown area of the state. Development and education of modern practices in the field of Agriculture, Horticulture & Forestry for sustainable livelihood of the rural masses is the main thrust of the service area of AUK.

    Studies on Genetic Variability, Characters Association and Genetic Divergence among Rice (Oryza sativa L.) Genotypes [
    (COLLEGE OF AGRICULTURE, UMMEDGANJ, KOTA, 2020-08-18) Meena, Deepak; Kumar, (Manoj
    The present investigation was carried out to estimate “Studies on Genetic Variability, Characters Association and Genetic Divergence among 25 Rice Genotypes for 10 characters viz., days to 50 per cent flowering, days to maturity, plant height, number of productive tillers per plant, panicle length, number of grains per panicle, 1000-grain weight, amylose content, protein content and grain yield per plant. The experiment was laid out in a Randomized Block Design with three replications at Agricultural Research Station, Ummedganj, Kota during Kharif 2019. The analysis of variance indicated the existence of significant differences among genotypes for all the characters studied. High GCV and PCV values were observed for grain yield per plant, number of productive tillers per plant, number of grains per panicle and 1000-grain indicating the presence of good amount of genetic variability for these characters so, direct selection for these characters would be effective. The characters viz., number of productive tillers per plant and grain yield per plant exhibited high heritability coupled with high genetic advance indicating the involvement of additive gene action in the inheritance of these traits hence simple selection would be rewarding. The result of character association indicated that grain yield per plant showed significant positive correlation with most of the traits except number of grains per panicle, amylose content and protein content at both the levels. Genetic divergence studies by Mahalanobis D² analysis indicated the existence of significant diversity among rice genotypes which were grouped into six clusters. Greater genetic divergence was found between cluster III and VI. Cluster II was the largest comprising of eight genotypes and other clusters viz., cluster I contain seven genotypes, cluster III comprising four genotypes, cluster IV include three genotypes, cluster V include two genotypes and cluster I was represented by single genotype indicating high degree of heterogeneity among the genotypes. The pattern of group constellations indicated significant diversity among the genotypes.The cluster I having highest mean value for grain yield per plant and productive tillers per plant, cluster III for days to 50 per cent flowering, days to maturity and plant height, cluster IV for highest protein content and cluster V for number of grains per panicle and cluster VI having highest panicle length, 1000-grain weight and amylose content. The genotype RSK-1155-6-3-1, RSK-1157-4-5-1, RSK-1157-6-3-1, RSK-1157-9-2-2 and RSK-1155-3-3-1 were superior not only for grain yield per plant but also related traits like plant height, number of productive tillers per plant, days to 50 per cent flowering, days to maturity, panicle length, number of grains per panicle, 1000-grain weight, amylose and protein content. These superior genotypes may be directly used in future breeding programmes in rice.
