The best of the best: the portal for top lists & rankings: Strategy and business building for the data-driven economy: Show sources information The percent of fertile spikelets gradually declines when daily mean temperature exceed 29C [50] or 29.6C [51]. H. Witham, D. F. Blaydes, and R. M. Devlin, Exercises in Plant Physiology, PWS Publishers, Boston, Mass, USA, 2nd edition, 1986. callback: cb The country's urban population more than tripled between 1981 and 2017 (from 23.8million to 75.7million), as Pakistan's urbanisation rate rose from 28.2% to 36.4%. Directly accessible data for 170 industries from 50 countries and over 1 million facts: Get quick analyses with our professional research service. At 23 days after flowering, Heera2 and BRRI hybrid dhan2 showed significantly higher photosynthetic rate than BRRI dhan45, but the studied hybrid and inbred varieties exhibited decreasing trend of photosynthetic rate of the flag leaf at 9, 16, and 23 days after flowering in all planting dates. If a subject had more than 10 percent homozygosity, extreme inbreeding was more than likely the cause. Rice production stood at 7.44 million tons during 20172018 showing a record increase of 8.61% over previous years production of 6.85 million tons (Economic Survey of Pakistan 20172018). Four planting dates were maintained, namely, 20 December, 5 January, 20 January, and 5 February. The statistics in the graphs below were created by the United Nations in July 2022,[7] and are covered in more detail in the following section. Numerous smaller cities (such as Faisalabad, Rawalpindi, Peshawar, and the capital Islamabad) dot the rest of the country. Muslim Inbreeding: Impacts on intelligence, sanity, health and It is incumbent on all of us to educate and refuse to allow politicians and the media to sweep these important issues under the carpet. By 2025, You May Be Able To Stay In A Luxury Space Hotel Named After A Nazi. 1, pp. The present study suggested accumulation of more dry matter before heading and its higher translocation into the developing grain during filling stage resulting in higher yield of hybrids over the modern inbred. S. Q. Cao, Y. Q. Zhao, J. L. Wen, S. A. Wang, and R. X. Zhang, Studies on photosynthesis in flag leaves and its relation to grain filling course of high yield wheat, Scientia Agricultura Sinica, vol. This result confirms the findings of Yan et al. its recurrence is high. 172174, 2003. [22] and Yang et al. Was Hideki Tj A War Criminal Or Loyal Statesman? Hybrid rice varieties have higher yield potential over inbred varieties. (function() { In the present investigation flag leaf of the tested hybrid varieties contained higher amounts of chlorophyll and maintained higher chlorophyll a:b ratio over elite inbred BRRI dhan45. In Turkey, consanguinity has been shown to be directly related to the education of women18 whereas in our series, no such effects were noted and consanguinity was as common in uneducated population as in the educated. However, relatively high temperature impaired slow rate of remobilization and transportation of assimilates ultimately causes rapid reduction of the percentage of filled grain in the hybrids compared to the inbred variety. 61, no. 5, pp. The table below shows Pakistan's provinces and territories by their historical population. In the case of early planting, higher biomass accumulation and rapid expansion of leaf area of the tested hybrids produced higher LAI just after heading and developed an efficient sink (large panicles). Pakistan. event : evt, WebThe average level of inbreeding over the years varied from zero to 7.3%. inbreeding WebR BC = S[() n + n' (1 + F A)] v (1 + F B)(1 + F C) . Islam et al. [49] There are also smaller groups of Muslim immigrants from countries such as Burma, Bangladesh, Iraq, Somalia, Iran, Tajikistan, and Uzbekistan, among others. Inbreeding is common in the southeast region and more rural states, such as Eastern Kentucky. Perinatal malformation related mortality has recently been studied in Europeans and Pakistanis settled abroad7-9 (Table).One evident factorwas the different inbreeding coefficient of the two populations which probably was responsible for such significantly different results. Who is the most inbred person? Higher chlorophyll content in the flag leaves and its slow reduction toward maturity delayed senescence of the hybrid rice varieties (Table 4). Otorhinolaryn., 1984;18:97-106. RT @RoroniggaZolo: 70% of British Pakistanis are from Mirpur, a highly inbred and backwards area of Pakistan. Ten plants were sampled from each plot at heading and at maturity. About 70% of inbred families live in desolate areas. Leaf area index (LAI) increased gradually in all the tested varieties in all the planting dates up to heading and in most of the cases the differences are nonsignificant. The experiments were laid out in a split-plot design with three replications, placing planting dates in the main-plots and varieties in the subplots. 3, p. 33, 2009, Regd no. Saudi Med., 1993; 13:447-450. Punjabi is the most widely spoken language in Pakistan. S. S.

After 1984 nineteen rounds of PDS were completed till 2007. If you are an admin, please authenticate by logging in again. This study was only confined to visible or easily detectable malformations. and Thompson, MW Genetics, in medicine. Inbreeding is seen as a stereotype by the people of the region. 319325, 2010. The average modern day Japanese is descended from about 16 percent of Their findings were published in the journal Nature Communications and address a number of specific physiological, cognitive, and immunological health impacts. [57] Although only about 7% of Pakistanis speak it as their first language, it is widely spoken and understood as a second language by the vast majority of Pakistanis. "Pakistan: Fertility rate from 2010 to 2020." Filled grain (%) declined significantly at delayed planting in the hybrids compared to elite inbred due to increased temperature impaired-inefficient transport of assimilates. These are some maps of religious minority groups. Even in England, more than half of Pakistani immigrants are married to WebA 2005 BBC survey found that 55 percent of Britains huge Pakistani population was married to a first cousin. Child., 1989;64:1036-1041. India South Asia Asia Place . Complete analysis of malformed children (Figure 4) [42] found no variation in leaf chlorophyll content between hybrid and modern inbred varieties at Boro season (December to May) but in Aman season (July to December) recorded higher leaf chlorophyll content in hybrids over inbred rice varieties. The 2017 census recorded a population of 207,684,626 living in Pakistan's four provinces and the Islamabad Capital Territory. White tigers in captivity exist due to inbreeding. [22]. Flag leaf chlorophyll content and chlorophyll a:b ratio gradually decreased in the hybrid and inbred varieties with advanced maturity. 4, pp. The hybrids Heera2 produced significantly higher grain yield over inbred BRRI dhan45 at all planting dates except 5 February planting and an almost similar trend was observed for BRRI hybrid dhan2. } 41, no. Vertical bars represent standard error (, Source-sink relation and postheading crop growth rate of hybrid and inbred rice varieties at different dates of planting in dryseasons, 2008-200. Pakistan's Human Development Index (HDI) value for 2018 is in the medium human development category with a score of 0.560 (152nd rank out of 189 countries and territories) compared to 0.614 (135th rank) for Bangladesh and 0.647 (129th rank) for India. T. Horie, I. Lubis, T. Takai et al., Physiological traits associated with higher yield potential in rice, in Rice Science: Innovations and Impact for Livelihood: Proceedings of the International Rice Research Conference 16-19 September 2002, T. W. Mew, D. S. Brar, S. Peng, D. Dawe, and B. Hardy, Eds., pp. Kj. One hundred and thirty-five of these families had one additional child malformed, whereas, 10 had two malformed children in addition to the index child with whom they reported. 8, pp. Kulkarni14 in his study found malformations of major body systems to be significantly more common amongst consanguineous couples, whereas malformations of eye, ear and skin did not show any gross effects of consanguinity. Both hybrids accumulated higher amount of biomass before heading and exhibited greater remobilization of assimilates to the grain in early plantings compared to the inbred variety. The coefficient itself is calculated taking into account the total number of married couples, number of related couples, the number of various types of relationshiops and coefficients of relationships, using a complex formula 10 These relationships were used to calculate coefflcient of inbreeding in the families under study, but for the sake of statistical analysis, first cousins once removed were grouped with second cousins and second cousins once removed were considered together with distant relatives, The data was subjected to detailed statistical analysis. Recently, China has imposed new laws forbidding marriages between first and second cousins. [19], and Yang et al. The grain yield and its attributes of the tested varieties at different planting dates have been shown in Table 3. Inbreeding Plants of 12 hills from each plot were harvested at maturity to record the yield contributing components. Rakshani is the major dialect group in terms of numbers. } Furthermore, researchers found that the prevalence of extreme inbreeding was far higher than previously thought. Flag leaf chlorophylls were extracted using 80% acetone solution and were estimated with a double beam spectrophotometer (Model: U-2001, Hitachi, Japan) according to Witham et al. Social and genetic implications of customary consanguineous marriages among British Pakistanis. H. K. Poshtmasari, H. Pirdashti, M. Nasiri, and M. A.

[52][53] The majority Pakistan's languages belong to the Indo-Iranian group of the Indo-European language family. Ann. Perinatal mortality in different ethnic groups. Table of Contents Inbreeding statistics by state The U.S has a low inbreeding rate of about 0.1 to 0.2% only There are only 18 states listed to have inbreeding cases answer a questionnaire which included, among other variables, parents relationship to each other (whether first cousins (n=3 125), flrstcousins once removed (n=200), second cousins (n=330), second cousins once removed (n=50) and the couples who were related but the exact relationship could not be established distant relatives (n=115)). Inbred BRRI dhan45 exhibited higher ratio of grain dry matter accumulated from current photosynthetic assimilation to leaf area (average from heading to maturity) compared to both hybrids. In early plantings (20 December and 5 January), studied rice varieties took longer in the vegetative phase. Zahida, S.S.A. 811817, 2004. The leaf area development of studied varieties at different planting dates in 2009-10 was more or less similar to the previous year. [83] Differences with other Punjabi varieties are more pronounced in the morphology and phonology than in the syntax. Of these, 66 are indigenous and 8 are non-indigenous. With low death rates and a declining birth rate, the country is in the third stage of its Demographic transition. 33, no. [7] This data includes Azad Kashmir and Gilgit-Baltistan. Therefore, our estimate of the prevalence might be too low.. 766772, 2002. A few are highly endangered languages that may soon have no speakers at all.
