Despite the fact that Cyprinus carpio is third most culturable fish species in the world but due to pond breeder, it have constraint to over populate the pond, so overcome this problem, the present project “the role of androgen on masculinization and growth performance of Cyprinus carpio” was performed to determine the optimal dose rate of oral administration of the androgen 17α-Methyltestosterone (MT) for phenotypic sex reversal of C. carpio and comparing growth performance of sex reversed and normal C. carpio as well as in order to determine the effect of 17α-MT towards meat quality (proximate composition). The project comprised in two experimental phases i.e. phase I: sex reversal phase, in which sex reversal of C. carpio was done by oral administration of 17α-MT applied @ 0 (control), 25, 50, 75 and 100 mg.kg -1 of ornamental fish feed (30% crude protein), completed in five glass aquaria (70 litter capacity each) along with one replication, feeding @ 2% of wet body weight twice a time daily for 30days and phase II, the growth phase, was completed in 5 earthen ponds in which the growth performance of sex reversed and normal C. carpio feeding @ 2% of wet body weight along with organic manure (cow manure) @ 0.1gN/100g of fish body weight daily during the experiment periods of 281 days was monitored. Morphometric characteristics i.e. wet body weight and total length recorded showed statistically highly significant interaction on fortnightly basis and among the treatments (P<0.01). At the end of the project, sex evaluation and analysis of meat quality of experimental fish was performed. 100 % male population of C. caprio was achieved by 17α- MT @ 100mg.kg -1 of feed with respect to 50% male population in control treatment, resulting in increasing trend of crude protein and fat deposition as hormone (MT) concentration increased, yielding maximum 2398.83 kg gross fish production.hec -1 .yr -1 as compare to control treatment 50% male with minimum growth yield by control treatment was 1693.58 kg gross fish production.hec -1 .yr -1 .

جہانِ رنگ و بو سب عارضی ہے
نبیؐ کے عشق کا رنگ دائمی ہے

بیانِ وصفِ یکتائیِ گُل سے
چمن زارِ سخن میں دلکشی ہے

بہ فیضِ مدحِ ممدوحِ اِلٰہیؐ
خدا کی ہم نوائی مل گئی ہے

وہی شمس الضحیٰ ، بدرالدجیٰ ہیں
اُنہی کی چار سُو جلوہ گری ہے

کھلے گا غنچۂ شوقِ تمنّا
مری اُمید کی کونپل ہری ہے

کہیں گے ان شاء اللہ ایک دن ہم
’’مدینے تک رسائی مل گئی ہے‘‘

Pada siklus I aktivitas siswa diperoleh dengan rata-rata secara klasikal 62, 93% yang termasuk dalam kualifikasi Baik. Pada siklus 2 aktivitas siswa mengalami peningkatan dengan rata-rata persentase aktivitas siswa 71, 16% dengan kualifikasi baik. Artinya terdapat peningkatan 6, 23%. Hasil belajar siswa pada siklus 1 dengan rata-rata yang diperoleh 60, 00 dengan kualifikasi cukup baik dan meningkat pada siklus 2 dengan rata-rata yang diperoleh 81, 94 dengan kualifikasi Baik. Artinya terdapat peningkatan sebanyak 21, 94. Berdasarkan hasil penelitian dapat disimpulkan bahwa penerapan pendekatan keterampilan proses dasar berbasis lingkungan dapat meningkatkan aktivitas dan hasil belajar pembelajaran matematika kelas VI SDN 156/III Tangil Kabupaten Kerinci.

Phenotypic and Genetic Attributes Conferring Non-Specific Resistance Genes Against Leaf and Stripe Rusts on Wheat

A comprehensive germplasm evaluation study of wheat elite lines was conducted at Wheat Research Institute Faisalabad to identify new sources of leaf and stripe rust resistance and high yield potential during crop seasons 2015-2017. The parents’ lines were selected on the basis of phenotypic characteristics and slow rusting history of race non-specific resistance genes by the selection of desirable parents used in a filial generation (F1-F5). In primary evaluation, total 855 head rows (F6 generation) were selected among F5 generation and screened. Among these, 112 lines were found to be resistant and these were further assayed for leaf and stripe rust resistance, yield performance and the presence of race non-specific rust resistance genes through phenotypic and molecular markers. The second round of evaluation identified 44 lines potentially resistant to both leaf and stripe rust under field conditions. Environmental factors played a great role on the progress of leaf and stripe rust disease severities during both crop seasons 2015-2017. Maximum lines showed statistically significant correlation with all environmental conditions. A positive linear relationship was observed between temperature (minimum and maximum), relative humidity, rainfall and wind speed and leaf and stripe rust disease severity. The phenotypic and molecular investigation confirmed 10 elite lines demonstrating the linkage of three designated slow rusting/race non-specific resistance genes (Lr34/Yr18, Lr46/Yr29, and Sr2/Yr30). Among 112 advanced lines, under yield testing trial 14 lines (cluster-V) demonstrated highest mean values for all traits i.e. plant height (cm), grain yield (Kg ha-1), protein (%), 1000 grain weight (g), spike length (cm) and number of spikelet per spike as compared to all check varieties. It was concluded that CHENAB2000/INQ.91/5/WBLL1*2/ 4/SNI/TRAP#1/3/KAUZ*2/TRAP//KAUZ; PB-36259-0A-0A-0A-12A-0A (V-70003), 87094/ERA// PAK-81/2*V-87094/3/SHAFAQ-06/4/MAYA/PVN; PB-36369-0A-0A-0A-11A-0A (V-70034), FSD.08/6/BABAX/3/FASAN/Y//KAUZ/4/BABAX/5/LU26/HD2179/7/PB.96/87094/MH.97; PB. 37082-0A-0A-0A-19A-0A (V-70054), CNDO/R143//ENTE/MEXI_2/3/AEGILOPSSQUARROS A(TAUS)/ 4/WEAVER/5/PICUS/6/TROST/7/TACUPETOF2001/8/ CROW''S''/NAC//BOW''S''; PB No.36830-0A-0A-0K-12A-0A (V-70070); WHEAR/KRONST ADF2004//KAUZ/SITE; PBNo.36880-0A-0A-0K-11A-0A (V-70085), CNDO/R143//ENTE/MEXI_2/3/AEGILOPSSQUAR ROSA(TAUS)/4/WEAVER/5/IRENA/6/LERKE/7/TAN/PEW//SARA/3/CBRD; PBNo.369760 A-0A-0K-4A-0A (V-70103) and CNDO/R143//ENTE/MEXI_2/3/AEGILOPSSQUA RROSA(TAUS)/4/WEAVER/5/IRENA/6/LERKE/7/TAN/PEW//SARA/3/CBRD; PB No. 36976-0A-0A-0K-10A-0A) (V-70104) were most prominent crosses yielded lines and showed the combination of three slow rusting genes. None of these lines showed race specific/complete resistance, but were of slow rusting type and were suitable for commercial cultivation. Virulences analysis of leaf and stripe rust race populations was carried out to observe virulence pattern in the country through avirulence/virulence formula. The surveys were carried out on the rust traps nurseries consisted of 39 leaf and 27 stripe rust near-isogenic lines planted at different locations in Pakistan. The results showed that there were no virulence patterns for genes Lr18, Lr19, Lr23+(GAZA), Lr28, Lr29, Lr32, Lr34, Lr35, Lr36 and Lr37 and Yr1, Yr3, Yr4, Yr5, Yr8, Yr9, Yr10, Yr15, Yr17, Yr18, Yr26, Yr28, Yr29, Opata, Yrcv, Yrsp, Super Kauz, PBW-343 and Aoc+Yra. Among varieties FSD-08, PB-11, AARI-2011, Millat-11 and AAS-11 exhibited effective resistance to both leaf and stripe rust pathotypes.
