Cultivars and correlation

The normalized difference spectral index (NDSI) was used to determine significant wavebands that showed the best correlation with leaf ozone injury. The correlation coefficient (r) between NDSI and OIP were ranged from -0.79 to 1. Normalized difference spectral index, NDSI [R564,R568], and NDSI[R558,R573] were identified as the best Pearson’s correlation with leaf ozone injury percentage with correlation coefficient more than 0.96.

Improving cotton fiber length without reducing yield is one of the major goals of cotton breeding. However, genetic improvement of cotton fiber length by breeding has been a challenge due to the narrow genetic diversity of modern cotton cultivars and negative correlations between fiber quality and yield traits.

The present study emphasized on determination of the nature and magnitude of variability, heritability and genetic advance on yield and yield attributing characters in 19 potato genotypes harvested on different date. The estimation of correlation co-efficient among the characters along with their direct and indirect effect on yield is necessary to carry out proper selection on the basis of the traits. Wide ranges of variation have been observed for all the traits both in early and late harvesting situation.

An experiment was conducted with 32 cultivars of dahlia (Dahlia variabilis L.) to study correlation and path analysis among the yield attributing traits and their effect. Correlation among component characters showed that flower yield per plant had a highly significant positive genotypic correlation with leaf area index (0.617), crop duration (0.771), flowering duration (0.800), tuber weight (0.668) and change in fresh weight at day 3.

Field trials were conducted to study the effect of physical and chemical mutagens (Gamma rays, Ethyl Methane Sulphonate (EMS) and Diethyl sulphate (DES)) on biometric characters viz., days to 50% flowering, plant height, number of branches, fruits per plant, fruit length, fruit girth, fruit weight and fruit yield per plant and their correlations in five brinjal cultivars viz., Angoor, Annamalai, Hissar pragath, PLR 1 and Putheri. The results revealed that there had been strong association between number of fruits per plant and fruit weight with fruit yield per plant in M2 generation.

The investigation was focused on transfer of the Fusarium wilt resistance into elite cultivar. Screening of chickpea parents (ICC 506 EB and Vijay), 196 RIL’s (Obtained from ICRISAT, Hyderabad), F2and BC1F1 populations for Fusarium wilt resistance were done by Pot culture method and wilt sick plot method. The BC1F1 segregated in 1:1 ratio for resistance and susceptibility and F2 progenies segregated in a ratio of 1 resistant and 3 susceptible.

Surface area of fruits and vegetable are often estimated by assuming that they resemble a geometrical shape from which surface area can be mathematically calculated. A composite geometrical shape nearing to obovate shape was presumed for papaya fruit cultivars Red Lady and its geometrical shape was correlated with actual surface area (estimated by measuring the area of aluminium foil required to cover the fruit surface- wrapping and scanning method). Geometrical surface area was found to be more than 95 accurate when compared to wrapping and scanning method.

Genetics of quality parameters and their associations with grain yield and its component traits have a direct bearing on devising effective strategies for breeding biofortified crop cultivars. A newly developed 54 hybrids of pearl millet showed large genetic variability for yield and nutritional traits. Correlation studies revealed that single plant yield has positive significant correlation with the agronomic traits viz., plant height, number of productive tillers, test weight, single head grain weight and quality traits viz.

Grain yield in rice is considered as a complex trait, determined by the ultimate expression of its individual component traits. Establishing an association between yield and its component traits plays a vital role in stabilizing the trait ‘overall yield’. Correlation and path analysis were examined in 46 rice genotypes including tropical japonica accessions, indica land races and elite indica cultivars as New plant type (NPT) core set along with checks during kharif 2017.

Sorghum (Sorghum bicolor L. Moench) cultivars store non-structural carbohydrates predominantly as either starch in seeds (grain sorghums) or sugars in stems (sweet sorghums). Previous research determined that sucrose accumulation in sweet sorghum stems was not correlated with the activities of enzymes functioning in sucrose metabolism, and that an apoplasmic transport step may be involved in stem sucrose accumulation.

Very few studies are interested to the volatile compounds of pomegranate and evoking their potentials, especially, their antibacterial activity. In the present study, edible (arils) and non-edible (peels) parts of five pomegranate varieties (Tounsi, Kalai, Zahri, Chelfi and Garci) were compared for their phenolic contents, antioxidant activity, aroma profile and antibacterial propriety of their volatile compounds. Results showed that peel of the five varieties contained higher content in phenolics, flavonoids, tannins, anthocyanins and carotenoids additionally to higher antioxidant power.
