“…Number of leaves 6 and 10 weeks and plant height at 6 weeks have direct third order impact on economic yield. Similar to this, Patil (2011), also reported a positive association between seed yield of sunflower and plant height while Selvi et al (2016) reported a negative association between grain yield as primary trait and the number of leaves and plant height in pea. Traits with direct association with seed yield provide basis for selection and improvement (Selvi et al, 2016;Rasitha et al, 2019).…”

Soybean (Glycine max (L.) Merrill) a multipurpose food and fodder, is an important source of quality protein and oils. Despite this, its breeding-true ability which has implication for seed re-use, association between grain yield and other traits and its suitability for southern guinea savannah of Nigeria are not established. Hence, the objectives of the study are to determine the: i. genetic consistency of seed trait; ii. adaptability of late maturing variety of soybean and iii. establish the association between primary traits and yield. Data collected on growth and yield parameter in 16 genotypes were analyzed using SAS. Path analysis was used to show cause-effect relationship while dendogram depicted the association among line. The result revealed wide genetic diversity among the TGX genotypes and association between farmers seeds and commercial seeds. The lines were also true to type for grain yield and other characters. Hence, resource poor farmers can save good yielding seeds harvested, for planting in subsequent season. Breeders can use traits such as vigor, the number of branches and leaves at 10 weeks, plant height and the number of leaves at 6 weeks with direct positive and significant relation with economic yield to improve yield. Genotypes TGX 2008-2F, TGX 2007-11F and TGX 2009-16F are promising lines and better replacement to the local check. Therefore, further breeding efforts could be carried out to improve the lines for grain yield and fodder in order to achieve dual usage for the soybean lines and hence enhance food and nutritional security and improve livelihood of resource poor farmers in Nigeria.

“…Comparable results were reported by Pal and Singh [11] was observed highly significant correlation with days to 50 per cent flowering, the number of seeds/ pod and number of pods/plants. Selvi et al, [12] was noted a significant correlation for days to 50% flowering, pod length, number of pods/plants. Similarly, Pandey et al [13] noted for several green pods, number of node per plant, length of a pod (cm), plant height (cm).…”

An experiment was layout at the Horticulture Research Centre, SVPUAT, Meerut During 2018-2020 to estimate correlation coefficients and path coefficient analysis in Table pea using 36 genotypes including eight parents and 28 F1 on nine quantitative characters. Correlation coefficient result showed that seed yield per plant have highly significant and positive correlation with number of pods per plant (0.821, 0. 818), length of first fruiting node (0.587, 0.585), number of seeds per pod (0.547, 0.517), days to 50% flowering (0.467, 0.464), plant height (0.447, 0.447), width of pod (0.387, 0.284), length of pod (0.375, 0.363) and number of first fruiting node (0.353, 0.349). Path coefficient result showed that the highest positive direct effect on seed yield per plant was exhibited by several pods per plant, several seeds per pod and days to 50% flowering at both genotypic and phenotypic level.

“…Yield being a complex quality feature governed by several constituents' attributes. So choices for characters associated to yield have to be taken in to consideration (Selvi et al, 2016). Correlation assists in determining the real component of the return that is a complicated feature.…”

Background: Cauliflower is one of the foremost vegetable among all Cole crops. It contains an incredible amount of essential nutrients and vitamins. Being the second most important crop among all Cole crops, cauliflower contributes to overall vegetable productivity. The principal objective of this study is to evaluate the different genotypes on the basis of horticultural traits, so that can be further utilized in crop improvement programs. Methods: The present experimentation was initiated with fifteen diverse cauliflower genotypes. The trial was set up with a RCBD along with 3 replications, during the year of 2018-2019 at Lovely Professional University, Phagwara (Punjab). Result: Correlation analysis showed that yield of curd per hectare exhibited highest positive and significant correlation with leaf width, curd diameter, depth of curd, stalk length of plant, leaf length, net curd weight, days to curd initiation, gross plant weight, harvest index, marketable curd weight and days to curd maturity. Highest positive and direct effect was observed on yield of curd with marketable curd weight, leaf width, net curd weight, gross plant weight, length of plant stalk, harvest index, days to curd maturity, days to curd initiation, curd depth, Leaf lamina length, curd index and curd diameter.
