The present investigation entitled “Genetic variability, heritability and genetic advance in rice (Oryza sativa L.) under salt affected soil” comprised of 7 lines and 3 testers recommended for sodic soil. Crosses were made in “line x tester mating design. Thus 21 crosses (F1‟s) were produced during[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]
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]
units of 5¢-nGAAn-3¢. HSEs are separated into threetypes: perfect (P), gap (G) and step (S) [3]. P-typeHSEs have three inverted repeats in a contiguous array(nTTCnnGAAnnTTC). G-type HSEs have two consec-utive inverted sequences, with the third sequence sepa-rated by 5 bp (nTTCnnGAAn(5[r]
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]
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]
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]
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]
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]
In cocoa, four yielding categories viz., [‘Low’ ( 3.0 kg)] were evaluated for standardization of seedling selection criteria at nursery stage. The results showed that the highest germination percentage, seedling height, girth, number of leaves, leaf area and seedling vigour were registered in high a[r]
The present investigation was carried out in 73 eggplant genotypes to assess the nature and extent of genetic variability, heritability and genetic advance under normal (0% PEG-6000 as control) and osmotic stress condition (12 % PEG-6000) in germination phases in three replications in a completely r[r]
The development of biotypes and existence of variability in Brown planthopper population always demands for the identification of new sources of resistance from time to time. However, the presence of desirable quality and yield traits in the genotypes along with source of resistance to BPH will be a[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]
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]
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]

Genetic parameters like variability, heritability and genetic advance were studied in a set of 60 genotypes of roselle (Hibiscus sabdariffa L.) during Kharif, 2013 and 2014 in North Coastal Zone of Andhra Pradesh at Agricultural Research Station, Ragolu, Srikakulam district for seed yield and its co[r]
The correlation and path coefficient analysis were studied in twenty five genotypes in chilli for 15 different qualitative and quantitative characters. Correlation coefficients at genotypic and phenotypic levels indicated that fruit yield per plant was positively and significantly correlated with fr[r]
Okra genotypes were evaluated for their genetic variability, character associationships and genetic divergence among fifteen quantitative traits by adopting Randomized Block Design. Significant variation were observed for all the traits except incidence of YVMV at 30 DAS indicating the vast scope fo[r]
