GENETIC MAPPING OF QTLS FOR PHYSIOLOGICAL TRAITS IN RICE (ORYZA SATIVA L.) BY USING DANTESWARI/DAGGAD DESHI RIL POPULATION

Drought is a major constraint in rice- growing areas of Asia. Identification of genomic regions containing QTLs governing drought tolerance traits is inevitable for developing novel genotypes with enhanced drought tolerance. A RIL population of 122 lines derived from a cross of Daggaddeshi/Danteswar[r]

A study provides a realistic basis for allocation of weightage to each attributes in deciding a suitable criterion for genetic improvement. The analysis of correlation coefficient along with information on path coefficient helps considerably in identification of suitable characters for yield enhance[r]

Zinc deficiency which leads to “Khaira” disease is the major micronutrient problem in rice. It can be corrected by applying zinc supplements to the soil or plant which will put burden on resource poor farmers. Present investigation was taken to map QTLs for zinc deficiency tolerance to zinc deficien[r]

Upland rice grows on 19 million ha, about 15% of the world''s rice plantation [2]. The production of upland rice is crucial to agricultural economy of many countries [15]. The yield of upland rice is very low with an average of about 1 t/ha. Drought is a major constraint to the productivity of uplan[r]

Rice is the major staple food of the world’s population which contributes a vital role in global food security. Scarcity of water resources is a major threat for the higher water requiring crops like rice and agricultural production, as a whole. Henceforth, the present field experiment was conducted[r]

Micronutrient malnutrition is a serious health concern resulting due to deficiency of minerals such as iron and zinc in dietary intake. Genetic enhancement of crops with higher mineral content i.e. bio-fortification is one of the most cost effective method to solve the global mineral malnutrition pr[r]

An investigation was carried out at Agrometeorological field, Central Research Farm, Odisha University of Agriculture and Technology, Bhubaneswar in rabi season, 2017 in natural condition on study of various aspects of effect of weather (maximum temperature, minimum temperature, rainfall, maximum re[r]

A field experiment was conducted to investigate the methods of cultivation and optimization of nitrogen requirement of rice crop in coastal alluvial soils, Karaikal, Pondicherry, India. Experiment was laid out in a split plot design with methods of rice cultivation as main plot treatment consisted o[r]

A field experiment was conducted at Water Technology Centre, College farm, Rajendranagar, Hyderabad during kharif, 2015 to study the “Response of different varieties of aerobic rice (Oryza sativa l.) under drip fertigation levels.” The experiment was conducted with three main treatments and four sub[r]

The present study was carried out to assess the level of genetic diversity among sixty-four rice bean genotypes by using morphological and RAPD markers to aid in the selection and efficient utilization of diverse genotypes in improvement of rice bean.

Sowing time of rice sometimes get delayed due to lack of assured irrigation or surplus of rainfall. Moreover, no specific varieties have been specifically developed for this purpose. An experiment was conducted to study the effect of sowing dates and varieties on economics and soil properties of dir[r]

There have been numerous attempts to transfer Papaya ringspot virus type P (PRSV-P) resistance from wild Vasconcellea relatives to Carica papaya L. Success has been limited by the high degree of genetic divergence and incompatibility. In the present work, the advanced intergeneric population of Cari[r]

Source and sink activity measured after anthesis in six poplar rice cultivars. The experiment was laid in randomized block design with six cultivars MTU-1001, MTU1010, MTU-7029, BPT-2231, BPT-3291 and BPT-5204 replicated four times. After anthesis, top three leaves separately, top three internodes c[r]

Stay green trait is reckoned as a favourable and desirable trait which can beacon the path to achieve enhanced yield potential in crops including rice. In this study, the correlation and path analysis for several physiological and genetic traits were carried out using six elite rice genotypes namely[r]

A pot culture experiment was conducted in earthen pots contains 5 kg of well mixed air dried red sandy loam soil. The rice var. BPT 5204 used as test crop. Carefully selected uniform sized seeds were directly sowed in each pot.

Horse gram [Macrotyloma uniflorum (Lam.) Verd.] is one of the highly nutritious minor pulse crop and has number of desirable traits like drought tolerance, high protein content, antioxidant activity, antimicrobial and medicinal properties. A total of 66 genotypes of horse gram comprising 61 accessio[r]

Thirty two hybrids developed from crossing four CMS lines with 8 restorers were studied among with parents for 14 yield and yield attributing characters. Among the male parental lines, JGL 18047, IET 26264 and RNR 26060 appeared the best general combiners for yield and important yield component trai[r]

Rich genetic potential with wide spectrum of genetic variability is a key factor behind a successful breeding programme. New recombinants can be generated through crossing between highly diverse parents. Genetically diverse 281 RILs and their parents were grown in randomized block design in two repl[r]

A field trial was conducted to investigate the effect of spatial distribution and different levels of nitrogen on growth of hybrid rice variety PA 6201, comprising of 16 different treatments using randomized complete block design with three replications at agronomy research farm of Narendra Deva Uni[r]

A field experiment was conducted to study the on farm crop response to plant nutrients in pre dominant cropping system i.e. rice, (Oryza sativa) - chickpea (Cicer arietinum) and their impact on productivity, soil fertility and economics at Kabirdham district of Chhattisgarh state during 2013-14 and[r]
