ASSESSMENT OF CORRELATION AND PATH COEFFICIENT ANALYSIS FOR YIELD AND IT’S ATTRIBUTING TRAITS IN RICE (ORYZA SATIVA L.) GENOTYPES

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]

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]

The present experiment material comprised of twenty two advanced breeding lines with two checks developed at department of genetics and plant breeding, Agriculture college Shivamogga.

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]

Sixteen genotypes of fennel were evaluated at Main Seed Spices Research Station, S. D. Agricultural University, Jagudan, Gujarat during rabi 2015-16, for estimates of variability, heritability and genetic advance in eight quantitative traits, viz., plant height, number of branches per plant, days to[r]

The present study was undertaken under rainfed situation in three locations to identify stable genotypes of Pigeonpea for seed yield and its component traits.

An investigation was carried out to study the influence of pre-rice incorporation of organic manures viz., green manure and farm yard manure (FYM) and simultaneously, the effect of inorganic source of Nitrogen at different levels was also studied to assess the influence of graded Nitrogen levels on[r]

Twenty hybrids of linseed generated by crossing of 5 lines and 4 testers in line × tester mating design were sown along with their nine parental lines to assess the extent of average heterosis over heterobeltiosis for seed yield and its component traits during Rabi, 2014-2015 and 2015-2016. This exp[r]

For yield and quality enhancement production techniques play a critical role. Among the various crop management strategies, weed management is an important practice which significantly contributes to yield and quality improvement of onion.

A field experiment was conducted during Kharif season of 2015 at Chaudhary Charan Singh Haryana Agricultural University, Rice Research Station, Kaul, India to study the phenology, and various agrometeorological indices viz., accumulated growing degree days (GDD), helio thermal units (HTU), photo the[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]

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]

The present experiment was conducted in randomized block design with three replications in summer season 2016-17 at the Main Experiment Station of the Department of Vegetable Science, NDUA&T, Kumarganj, Faizabad. Total 22 genotypes were taken for study including two checks. Observations were recorde[r]

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]

The field experiment on rice crop was conducted at research farm of C.S.A. University of Agriculture & Technology Kanpur, during Kharif season 2013-14. The doses of experiment were 50% NPK, 50% NPK+ S40, 50% NPK + S40 + Zn5, 50% NPK +Zn5, 100% NPK, 100% NPK + S40, 100% NPK + Zn5 and 100% NPK + S40 +[r]

A field experiment was conducted in Randomized complete block design to understand the effect of selective pre and post-emergence herbicides on physiology of rice crop in terms of visual toxicity, flowering and grain filling during the late samba season (October 2019 – February 2020) at wetland farm[r]

Combining ability analysis for yield and its component under late sown condition in bread wheat involved ten diverse parents and their 45 F1s and their F2s indicated significance differences among the parents for gca and crosses for sca for all characters under studied.
