GENETIC VARIABILITY IN RICE GENOTYPES

In the present investigation 50 rice genotypes were used to study character association, path analysis and variability. The studies of variance among 50 genotypes for ten characters revealed that the genotypes differed significantly for all the characters under study.

Fourteen genotypes of cherry tomato were evaluated under modified naturally ventilated polyhouse at the Experimental Farm, Department of Vegetable Science and Floriculture, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur during autumn winter season, 2017-2018 for marketable yield and its compo[r]

A glass house experiment was conducted at Department of Entomology, IGKV, Raipur (Chhattisgarh), during 2014-15 to evaluate different rice genotypes for brown planthopper (BPH) resistance. A total of 392 rice genotypes were evaluated, of which 58 were from IRRI, 78 were aromatic types and rest 256 r[r]

Genetic variability is the prime objective for crop improvement fraternity. Higher the amount of variation for a character greater will be the scope of its improvement through selection. Fifty six genotypes of greengram were evaluated in RBD for estimation of genetic variability, heritability, genet[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]

Ten S1 lines along with three hybrids were evaluated in randomized block design at Instructional-cum-Research (ICR) Farm of Assam Agricultural University, Jorhat.

Total 9 SSR markers were utilized to study the genetic relatedness among all thirty genotypes of turmeric. Six identified SSR markers are highly informative for genetic studies and are extremely useful in distinguishing the polymorphism rate at a specific locus in turmeric. Primer pair’s viz., 11 an[r]

In the present investigation, the magnitude of specific combining ability variances was higher than that of general combining ability for all the characters under study except spikelet fertility (%), kernel length, kernel length/breadth ratio and kernel elongation ratio indicating greater role of no[r]

The present study was conducted at the experimental farm of ICAR Research Complex for Eastern Region, Patna, India in Kharif season 2016 with an objective to identify false smut resistance rice genotypes. False smut (Ustilaginoidea virens (Cooke) Takahashi) is of serious concern to the rice growers[r]

The present experiment was carried out to assess the nature and magnitude of genetic variability and divergence among 200 finger millet accessions including four check varieties viz., PRM-1, PRM-2, VL-352 and GPU-28 and also to identify diverse parents for use in further breeding programmes.

There is wide genetic diversity available in foxtail millet and characterizing these resources is a prerequisite for genetic improvement. Establishment of the distinctness and to understand the qualitative differentiation among 223 genotypes of reference set of foxtail millet comprising of core set,[r]

An investigation was carried out at cashew research station under AICRP on cashew Ranasinghapur, Bhubaneswar, Khurda, during the year 2015-2017, to study the variability in thirty land races of cashew. It was found that, the heritability was highest in canopy area per m2 (99.82%) and minimum was rec[r]

Oriental pickling melon (Cucumis melo var. conomon) is one of the melon group vegetables of the Cucurbitaceae, with high potential as commercial short duration vegetable in South India. Twenty five RAPD primers were used which generated a total of 182 bands, out of which 107 bands were polymorphic ([r]
