GohilAn experiment comprised of fifty diverse accessions of forage [Pennisetum glaucum (L.) R. Br.] was conducted in randomized complete block design with three replications during Kharif -2020 at Main Forage Research Station, Anand Agricultural University, Anand to study the genetic variability, heritability, genetic advance, characters association, path coefficient analysis and genetic diversity. Each genotype was grown in a single row of 5.0 m length with a spacing of 30 × 10 cm, inter row and intra row, respectively. Observations were recorded on five randomly selected plants for the characters viz., plant height at 50 % flowering (cm), tillers per plant, leaves per plant, leaf length (cm), leaf width (cm), stem thickness (cm), leaf: stem ratio, green forage yield per plant (g), dry matter content (%), dry matter yield per plant (g), crude protein content (%), crude protein yield per plant (g), neutral detergent fibre content (%) and acid detergent fibre content (%), whereas, days to 50 per cent flowering was recorded on plot basis.ThesisItem Open Access STUDY OF FLORAL BIOLOGY, AGRO MORPHOLOGICAL AND MOLECULAR CHARACTERIZATION OF BRASSICA spp. AND ITS WILD RELATIVES(DEPARTMENT OF GENETICS AND PLANT BREEDING B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2021) Patel Disha H.; Dr.Arna DasThe present experiment was undertaken in a set of 15 diverse genotypes of Brassica spp. and its wild relatives to procure information on variation in floral morphology, agro-morphological traits, reproductive biology, inter-relationship of the observed characters and also to assess genetic diversity through D2 analysis, as well as through molecular markers (SRAP). Ploidy level of all the genotypes was also determined through Flow cytometry. The genotypes under study were, viz., Brassica fruticulosa (Spain), Brassica fruticulosa (Japan), Brassica fruticulosa (India), Diplotaxis assurgens, Diplotaxis cretacia and Diplotaxis viminea, Pusa swarnim (Brassica carinata), Kiran (Brassica carinata), NPC 9 (Brassica carinata), GM 1 (Brassica juncea), GM 2 (Brassica juncea),GM 3 (Brassica juncea) and GDM 4 (Brassica juncea), Brassica tournifortii and Sangam (Brassica nigra).ThesisItem Open Access GENETIC VARIABILITY, STABILITY AND ASSOCIATION MAPPING IN MAIZE (Zea mays L.)(DEPARTMENT OF GENETICS AND PLANT BREEDING B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2021) Patel Rumit J.; Dr. D. A. PatelThe present investigation entitled “Genetic Variability, Stability and Association Mapping in Maize (Zea mays L.)” was carried out at three different locations of Gujarat, under the jurisdiction of Anand Agricultural University (AAU) during rabi 2020-21. Three different environments were made available by choosing three different locations of Gujarat i.e., Experimental Farm, Department of Genetics & Plant Breeding, B. A. College of Agriculture, AAU, Anand; Main Maize Research Station, Anand Agricultural University, Godhra and Agricultural Research Station, Anand Agricultural University, Sansoli. The objective of research was to extract information regarding genotypic and phenotypic variability, heritability, genetic advance, correlation, stability analysis over different locations as well as SSR marker based diversity analysis and genome wide association study for various quantitative and qualitative characters in maize and sweet corn.ThesisItem Open Access GENETIC VARIABILITY, CORRELATION AND PATH ANALYSIS FOR YIELD AND YIELD ATTRIBUTING CHARACTERS IN ALOE (Aloe barbadensis Mill.)(DEPARTMENT OF GENETICS AND PLANT BREEDING B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2021) Narigapalli Pavani; K. A. GeethaA field experiment entitled “Genetic variability, correlation and path analysis for yield and yield attributing characters in aloe (Aloe barbadensis Mill.)” was carried out at ICAR – DMAPR, Boriavi during 2019-21 using 26 genotypes of aloe in a randomized complete block design. The objectives of the study were to estimate the genetic variability, broad sense heritability, inter-character association and the direct and indirect effects of yield and quality attributing characters through path coefficient analysis. The result revealed that IC 310618, IC 310623, GUJ 1, NMRM 2 and IC 285629 were superior lines for gel and aloin yields. Aloin content (%) was recorded highest in IC 310623 (27.07%). Based on variability studies, parameters viz., plant height, leaf weight, leaf thickness, exudates yield per plant, leaves per plant and leaf breadth could be selected for increasing yield as they have high heritability coupled with genetic advance.ThesisItem Open Access GENETIC VARIABILITY, STABILITY AND ASSOCIATION MAPPING IN CASTOR (Ricinus communis L.)(DEPARTMENT OF GENETICS AND PLANT BREEDING B.

The objective of research was to extract information regarding genotypic and phenotypic variability, heritability, genetic advance, correlation among the traits, stability analysis over different locations and artificial screening for Fusarium wilt as well as SSR marker-based diversity analysis and genome wide association study for various quantitative and qualitative characters in castor.ThesisItem Open Access GENETIC DIVERSITY STUDIES IN CULTIVATED TETRAPLOID COTTON(Department of Genetics and Plant Breeding B. A. College of Agriculture Anand Agricultural University Anand, 2021) Dholariya Jayeshkumar Mukeshbhai; Dr. M. P. PatelAn experiment comprised of forty-five diverse accessions of G. hirsutum and G. barbadense cotton was conducted in randomized complete block design with three replications during Kharif - 2020 at Regional Research Station, Anand Agricultural University, Anand to study the genetic variability, heritability, genetic advance, correlation coefficient analysis, path coefficient analysis, genetic diversity and selection indices. Each genotype was grown in a single row of 6.30 m length with a spacing of 120 × 45 cm, inter row and intra row, respectively. Observations were recorded on five randomly selected plants for seven qualitative characters viz., stem hairiness, leaf shape, flower petal color, boll surface, boll shape, flower petal spot and position of flower stigma and fifteen quantitative characters viz., days to 50% flowering, days to 50% boll bursting, plant height (cm), monopodia per plant, sympodia per plant, bolls per plant, boll weight (g), seed cotton yield per plant (g), ginning percentage (%), seed index (g), lint index (g), oil content (%), span length (mm), fibre strength (g/tex) and fibre fineness (mv).
