“…Similar observations have been reported in upland cotton by Dheva and Potdukhe (2002), Preetha and Raveendran (2007), Amir et al (2012), Abbas et al (2013). The moderate PCV and GCV that were observed for girth and height increment were consistent with the reports by Girase and Mehatne (2002), Harshal (2010) in outturn studies of cotton. Such moderate phenotypic and genotypic coefficient of variation noticed for girth and height will require vigorous selection for improvement.…”

Cashew (Anacardium occidentale L.) is an important tropical cash crop cultivated in Ghana. It provides livelihood for about 200,000 people and contributes 6.1% to Ghana’s gross domestic product (GDP). Four Brazilian dwarf accessions were introduced to improve nut yield. Objectives of this study were to (1) assess the agronomic performance of the accessions across two contrasting ecologies, (2) determine environmental influence on juvenile growth, (3) determine the relationship between early vegetative growth and yield and (4) explore heritability and genetic advance for the measured agronomic traits. The experiment was laid out in a randomized complete block design with 3 replications. Results revealed significant (p < 0.05) environmental influence on growth and yield of cashew. Transitional savanna agro-ecology is more suitable for cashew growth and development. Crop year, location and crop year × location interactions also influenced most of the agronomic traits. Early growth characteristics alone were not enough to predict yield. Genotype B2 ranked highest yielding across the agro-ecologies. Moderate to high heritability and genetic advance estimates were observed for nut yield, plant height and girth, an indication of variability among accessions needed for cashew improvement in Ghana.

“…Seed index had a positive linkage with bolls per plant, boll weight and fiber length (Table 2) (Table 3). Dhivya et al (2014), Kaleri et al (2016), Kumar and Katageri (2017), and Rajamani et al (2015) estimated of 60.01%, 72.24%, 51.63% and 66.72% heritability correspondingly for seed index. Significant progress is possible through selection for this character.…”

Background: Cotton is known for fiber extraction and it is grown in tropical and subtropical areas of the world due to having hot weather. Cotton crop has a significant role in GDP of Pakistan. Therefore, the two-years research was conducted to estimate heritability and association among various yield contributing parameters of cotton, i.e., plant height, number of bolls per plant, number of sympodial branches per plant, seed cotton yield, boll weight, seed index, ginning outturn (GOT), fiber length, fiber strength, and fiber fineness. Results: Association analysis revealed that seed cotton yield had a significant positive correlation with plant height, number of bolls per plant, number of sympodial branches per plant, GOT, staple length and fiber strength. Staple length and fiber strength were negatively linked with each other. Estimates of heritability were high for all of the traits except the number of sympodial branches per plant and boll weight. Conclusion: The parent IUB-222 was found to be the best for plant height, the number of bolls per plant, boll weight, GOT, seed cotton yield, and seed index. The genotypes namely, NIAB-414 and VH-367 were identified as the best parents for fiber length, strength, and fineness. Among the crosses NIAB-414 × IUB-222 was the best for the number of bolls per plant, seed index, seed cotton yield and fiber fineness, whereas, the cross of NIAB-414 × CIM-632 was good for plant height. The combination of A555 × CIM-632 was the best for the number of sympodial branches per plant, boll weight, fiber length, and strength, and VH-367 × CIM-632 proved the best for GOT.

“…Its fiber industry comprises of 1815 textile and ginning units run by millions of the people which depends on cotton production (Khan, 2013). Due to its contribution in financial stability in more than 80 countries and multiple uses as lint and its by-products, it is called as "white gold" (Saeed et al, 2014;Dhivya et al, 2014). The upland cotton (G. hirsutum L.) has attracted valuable scientific interest of plant breeders due to its economic importance regarding yield and environmental suitability (Sun et al, 2019).…”

In Pakistan cotton production is low due to many biotic and abiotic factors. While considering the demand and importance of cotton crop, the development of high yielding and superior quality cotton genotypes is Abstract | The upland cotton (G. hirsutum L.) is utmost natural fiber used in textile industry. Awareness about genetic diversity is very essential for fruitful genetic improvement approaches. Correlation, principal component analysis (PCA) and cluster analyses were performed to estimate genetic diversity in 25 cotton genotypes. Correlation analysis revealed that days to first square, flower and boll opening were positively associated with seed cotton yield. Staple length and CLCuV % were negatively associated with fiber fineness and yield respectively. In principal component analysis, four out of 14 principal components were selected with Eigen value ˃1. The four principal components contributed 79.9% towards variability. In PC-I, there was maximum positive factor loading of earliness traits, fiber fineness and negative factor loading of sympodia per plant and seed cotton yield. In PC-II, there was maximum positive factor loading of bolls per plant and GOT % while negative factor loading for CLCuV % and fiber length. A biplot between PC-I and PC-II showed that major contribution towards variability of fiber fineness and earliness traits among the studied genotypes. In cluster analysis, 25 genotypes were allocated in four clusters. Cluster-I was the largest by having 10 genotypes while clusters-III and IV each having six genotypes, and cluster-II was the smallest having three genotypes.
