This book was released on 2012-11-27 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2012 in the subject Biology - Genetics / Gene Technology, Tamil Nadu Agricultural University (Madurai Agricultural College and Research Institute), course: Ph.D, language: English, abstract: An investigation in rice (Oryza sativa L.) was carried out subjecting six ‘lines’ and 15 ‘testers’ crossed in a Line x Tester mating design to estimate gene action, combining ability and heterosis for yield and drought tolerant traits under aerobic condition. The 21 parents were also surveyed using SSR markers. From the Line x Tester analysis, the hybrids exhibited significant variation among themselves for all the characters studied under aerobic condition. The study of gene action for drought tolerance and yield component traits revealed that all the traits exhibited dominant gene action which was predominant. Therefore, to harness the dominant gene effects, either heterosis breeding or selection at later generations would be an appropriate breeding methodology. Based on the per se performance of lines and testers, the following parents i.e., IR79128A (L1), IR79156A (L2), COMS14A (L5), COMS24A (L6), IR 80286-22-3-6-1R (T3) and IR7925A-428-2-1-1R (T4) were adjudged as the best parents and crosses involving them would be expected to throw desirable segregants for both yield and drought tolerant traits under aerobic condition. Based on the gca effects, the parents IR79128A (L1), IR70369A (L4), IR79156A (L2), BI-33 (T15), IR79582-21-2-2-1R (T5), KMP-105 (T11), T1 (IR 69726-29-1-2-2R) and MAS - 946-1 (T9) were the best general combiners and the crosses involving them would result in the identification of superior segregants with favourable genes for both drought and yield. Out of 21 parents evaluated based on per se and gca effects, three ‘lines’ viz., IR79128A (L1), IR79156A (L2) and IR70369A (L4) and three ‘testers’ viz., IR7925A-428-2-1-1R (T11), KMP -148 (T12) and BI-33 (T15) were identified as the best genotypes which will be utilized in further breeding programmes as parents for improvement of yield and drought tolerance under aerobic conditions. The cross combination IR70369A / MAS -26 (L4 x T10) was identified as the best for recombination breeding to get desirable segregants for yield and drought tolerant traits under aerobic conditions. The cross combinations viz., IR70369A / IR 7925A-428-2-1-1R (L4 x T4) and IR70369A / KMP-105 (L4 x T11) had high per se, sca effects and standard heterosis for drought tolerant and yield traits under aerobic conditions.

This book was released on 2014-02 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present was carried out on "Genetic analysis of yield component traits in rice. Diallel analysis was carried out based on the method I and model I as suggested by Griffing. Seven economically important yield components traits were evaluated based on per se performance, general and specific combining ability effects, gene action and heterosis. The cross ADT 36 x ADT 37 and ASD 16 x ADT 36 exhibited highly significant sca effects and highly significant heterosis for grain yield and for most of its yield component traits. Hence, these crosses can be exploited for heterosis breeding provided cms system is available in the genetic background of ADT 36 and ASD 16 and thereby amidst farming community."

This book was released on 2020 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice (Oryza sativa L.) is the staple food for a majority of the world's population, and uses 30% of the global fresh water during its life cycle. Drought at the reproductive stage is the most important abiotic stress factor limiting grain yield. The United States is the third largest exporter of rice, and Arkansas is the top rice-producing state. The Arkansas rice-growing region in the Lower Mississippi belt is among the 10 areas with the highest risk of water scarcity. Adapted U.S. rice cultivars were screened for drought resistant (DR) traits to find sources for breeding U.S. rice cultivars for a water saving agricultural system. A recombinant inbred line (RIL) population, derived from varieties Kaybonnet (DR) and ZHE733 (drought sensitive), termed K/Z RILs was chosen for genetic analysis of DR traits. The objectives of this research were to 1) analyze the phenotypic and grain yield components of the K/Z RIL rice population for drought-resistance-related traits, 2) evaluate the Abscisic Acid (ABA) response of the K/Z RIL rice population on root architectural traits in relation to drought stress resistance, 3) screen polymorphic molecular markers to identify genes linked to productivity traits of grain yield under drought stress, measured by number of filled grain per panicle using bulk segregant analysis (BSA), and 4) identify QTLs and candidate genes in the K/Z RIL population for drought resistance associated with vegetative morphological traits, grain yield components under drought stress and well-watered conditions, and root architectural traits related to ABA response. The RIL population was screened in the field at Fayetteville (AR) by controlled drought stress (DS) treatment at the reproductive stage, and the effect of DS quantified by measuring drought-related traits. ABA sensitivity was quantified by measuring root architectural traits at the V3 stage. Based on the filled grain per panicle number, 13.13% of K/Z RIL population and parent Kaybonnet were highly drought resistant, while 75.75% of RILs and parent ZHE733 were drought sensitive. Under ABA conditions, Kaybonnet and 48 drought resistant lines exhibit ABA sensitivity, implying regulation of osmotic stress tolerance via ABA-mediated cell signaling. Based on BSA screening, 13 polymorphic markers potentially linked to DR traits were identified. QTL analysis was performed with 4133 SNPs markers by using QTL IciMapping. A total of 213 QTLs and 628 candidate genes within the QTL regions were identified for drought-related traits. The RT-qPCR analysis of the candidate genes revealed that a high number of drought resistance genes were up-regulated in Kaybonnet as the drought-resistant parent. Information from this research will serve an important step towards improvement of adapted Arkansas rice cultivars for higher grain production under DS conditions.

Book excerpt: This book presents a wealth of both general and specific information about rice. The first section outlines the distribution and mutual relationships of various types of rice with special attention to the adaptive strategy of wild and cultivated rice, and to the relationships between different ecotypes and their adaptation to low temperature, different photoperiods or different humidities. The section on rice morpho-physiology compares the characteristics of rice and dry land crops and different ecotypes with regard to seed dormancy and germination; describes the important steps in the photosynthetic structure process and its adjustment to the course of evolution of cultivated rice; studies the root and nutrient uptake and the responses to hormones in terrestrial and aquatic plants; considers the reproductive nature in relation to tolerance to environmental stress; and discusses the morphological characteristics of rice panicle in relation to grain filling, sink-source balance and variation in yield components of panicle structure. The last section reviews the genetics of rice and includes new findings on chromosomal analysis, cytoplasmic analysis and gene analysis and reviews recent achievements in tissue culture and genetic engineering techniques.The book is authoritative, well-documented and international in scope. It presents new and useful information of direct use to rice research workers and students, and of interest to crop physiologists, agronomists, plant physiologists and breeders throughout the world.
