“…However, the use of heritability alone in advance generations is not adequate to bring significant improvement through selection if not accompanied with sufficient amount of genetic advance. Therefore, heritability when coupled with genetic advance could further strengthen the effectiveness of selection which has been documented by many researchers like, Ghosh and Gulati (2001); Akbar et al (2003); Iqbal et al (2003). Sometimes direct selection of complex traits such as yield could be misleading.…”

P akistan has diverse agro-ecological regions comprising both plains and mountains of Baluchistan, Punjab, Sindh, Khyber Pakhtunkhwa (KP), Azad Jammu and Kashmir and Gilgit-Baltistan. These regions include high precipitous valleys and irrigated plains. The environmental issues such as temperature fruitfulness status, soil distinctiveness and rainfall play a vital role in the varietal recital. Wheat is successfully grown in Khyber Pakhtunkhwa. It occupies 40% of the total cropped area and 60% of the area grown to cereals in the province. In 2013-14 the total area devoted to wheat cultivation in KP was 0.72 million ha, which produced 1.15 million tonnes of wheat with an average yield of 1590 kg/ha (GoP, 2015). Improvement in wheat production is essential for future purposes because of ever increasing population pressure. We need to develop such varieties that fulfil our nutritional requirements. Breeding objectives for bread wheat include suitability of different maturity groups for early, mild, and late planting and also special importance are given on high yield, resistance to diseases, resistance to lodging, wide adaptation, better milling, baking and nutritional qualities. Heritability and genetic advance are important to plant Abstract | Heritability plays a pivotal role in selection. Breeders could predict the performance of crop plants by knowing the magnitude of heritability. An experiment was conducted using a set of spring wheat genotypes to estimate heritability for various plant traits during crop season 2014-15 at the University of Agriculture, Peshawar. The randomized complete block design with three replications was used in the experiment. Data were recorded on yield and some other important plant traits like days to heading (days), days to maturity (days), flag leaf area (cm 2 ), spike length (cm), grains spike -1 (no.), grains weight spike -1 (g), biological yield (kg ha -1 ) and grain yield (kg ha -1 ). Mean performance of genotypes showed that all the spring wheat genotypes performed well for all the traits. Spring wheat cultivar Tatara showed best performance for maturity, similarly, genotype SM12 performed well for grains spike -1 and grain weight spike -1 , whereas, genotype SM4 performed well for grain yield. Relatively high heritability with low genetic advance was estimated for days to maturity, while moderate to high heritability coupled with genetic advance was recorded for other yield related traits. Correlation analysis showed that grain yield had strong positive phenotypic and genetic correlation with heading, maturity, flag leaf area and biological yield. Spring wheat genotype SM12 had best performance for grains spike -1 and grain weight spike -1 should be further tested at different location of Khyber Pakhtunkhwa for possible release as a new cultivar.

“…Krisnawati and Adie (2015) observed the similar results where a huge variation in harvest index (ranging from 31 to 44%) among the soybean genotypes was calculated. Karnwal and Singh, (2009), Namdari and Mahmudi (2013), as well as, Iqbal et al (2003) also reported the meaningful correlation between seed yield and other four attributions including harvest index. The results in the similar fashion demonstrated that high harvest index is the key high-level of yield soybean with is reachable only by allocation of most of the photosynthaste into reproductive organs (Kumudini et al 2002;Shadakshari et al, 2014: Jain et al, 2017.In the years' means value of soybean getnoypes the highest percentage of oil contents (21.43) were observed in KA08-08 statistically at par Bravo (21.16%) and Ataem-7 (21.09).…”

Background: Soybean is a most important crop providing edible oil and plant protein source for human beings, in addition to animal feed because of high protein and oil content. This study was conducted to find out the suitability and the performance of 14 soybeans [Glycine max (L.) Merr.] varieties/advance lines in the growing seasons of two consecutive years 2017 and 2018.Methods: A randomized complete block design with four replications was used at research area of GAP Agricultural Research Institute, Sanliurfa, situated in Southeast region of Turkey. The data regarding different parameters including days taken to days taken to flower initiation (days), days taken to physiological maturity (days), growing degree days (days), plant height at harvest (cm), number of pods, 1000 grain weight (g), grain yield kg da-1), crude oil (%) and protein (%) were recorded during the course of study. Result: The variety Sa-88 and advance line KA08-03 were the highest grain yielders (3705 and 3660 kg/ha, respectively) among others. Though the qualitative characters were statistically significant but the difference was not much higher. Both the cultivar and line presented good yield making the results possible for rural extension to confirm the suitability of these genotypes to be used to support the ever-increasing demand of soybean meal and oil domestically.

Soybean {Glycine max (L.) Merill} is not only an important food source containing fat, protein, carbohydrate and minerals but also an important industrial plant providing raw material for many industries. Organic farming is an important element for sustainability of farming, protection of environment, and reduction of chemical fertilizers usage. Soybean, like other legumes, has rhizobium bacteria in its roots providing nitrogen and organic materials which facilitate the sustainability of organic farming. This study was conducted with the aim of researching the effects of the organic cattle manure doses on yield and yield elements of soybean under semi-arid climatic conditions in organic farming. In this study, organic cattle manure with the doses of 0, 500, 1000, 1500 and 2000 kg ha -1 were applied to Adasoy Soybean [Glycine max (L.) Merill] cultivar under the second crop conditions. There search was conducted according to the random blocks experimental design with three replications during 2013 and 2014. In results obtained from the twoyears study determined that the seed yield varied between 1678.9 and 2611.8 kg ha -1 ; plant height varied between 87.00 and 112.00 cm; number of branches per plant varied between 3.04 and 6.28; first pod height varied between 7.68 and 12.81 cm; number of pod per plant varied between 103.83 and 138.66 per plant -1 ; protein ratio varied between 39.31% and 41.74%; 100 seeds weight varied between 12.49 g and 15.28 g; and oil ratio varied between 20.51% to 21.91%. According to the results of correlation analysis, positive and important correlations between seed yield with number of branches per plant (r=0.4964**), and number of pod per plant (r=0.4964* ) and 100 seeds weight (r=0.5782**) were observed.Öz: Soya {Glycine max (L.) Merill} içerdiği yağ, protein, karbonhidrat ve mineral maddeler ile önemli bir besin kaynağı olmakla birlikte pek çok sanayi koluna hammadde sağlayan önemli bir endüstri bitkisidir. Ayrıca sürdürülebilir tarımın sağlanması, çevrenin korunması ve kimyasal gübre kullanımının azaltılmasında organik tarım, önemli bir unsurdur. Soya baklagil bitkisi olması dolayısıyla köklerindeki rhizobium bakterileri sayesinde, toprağa azot ve organik madde sağlamakta ve tarımın sürdürülebilirliğini kolaylaştırmaktadır. Bu çalışma yarı kurak iklimin organik tarım koşullarında, soyanın verim ve verim unsurlarına, organik büyükbaş hayvan gübresi dozlarının etkisini araştırmak amacıyla yürütülmüştür. Çalışmada; Adasoy Soya (Glycine max [L.] Merill) çeşidine ikinci ürün koşullarında organik büyükbaş hayvan gübresi 0, 500, 1000, 1500 ve 2000 kg/ha dozlarında uygulanmıştır. Çalışma tesadüf blokları deneme desenine göre 3 tekerrürlü olarak 2013 ve 2014 yıllarında yürütülmüştür. Çalışmadan elde edilen iki yıllık birleştirilmiş varyans analiz sonuçlarına göre; verimin 1678.9-2611.8 kg/ha; bitki boyunun 87.00-112.00 cm; bitkide dal sayısının 3.04-6.28 adet/bitki; ilk bakla yüksekliğinin 7.68-12.81 cm; bakla sayısının 103.83-138.66 adet/bitki; protein oranının % 39.31-41.74; 100 tane ağırlı...
