BOTANICAL DESIGNATION 
     
       Petunia×hybrida  
     
     CULTIVAR DENOMINATION 
     ‘Sunpetu 1072’ 
     CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is related to and claims priority under 35 U.S.C. 119 to U.S. provisional plant patent application 61/960,548, filed Sep. 20, 2013, entitled ‘Sunpetu 1072.’ 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct variety of  Petunia  plant, which is hereinafter referred to as ‘Sunpetu 1072.’ 
     A  Petunia  is a very popular plant that is used in flower bedding and potting in the summer season. 
     This purpose of this invention is to obtain a new  Petunia  cultivar with vigorous and trailing habit, abundant flowering, the whole bush remaining in bloom for a considerable period of time, and double, small sized and light greenish yellow colored flowers. 
     The new  Petunia  plant originated from cross-pollination of the female parent ‘MP22-176-1’ and the male parent ‘MP22-138-2’. The female parent ‘MP22-176-1’ (unpatented) used in the crossing of ‘Sunpetu 1072’ is a strain of the applicant&#39;s breeding lines (i.e., proprietary  Petunia  selection), having yellow petals, and the male parent ‘MP22-138-2’ (unpatented) used in the crossing of ‘Sunpetu 1072’ is a strain of the applicant&#39;s breeding lines (i.e., proprietary  Petunia  selection), having white petals. The cross-pollination was conducted in Sep. 10, 2010 at Yame-gun, Fukuoka, Japan. 
     In March 2011, the seedlings obtained by the crossing were planted in a field. In May 2011, some seedlings were selected in view of growth habit, flower size and color thereof. Shortly thereafter stem tip culturing was carried out, and then the propagation was started. 
     In November 2012, the cultivation of the seedlings was repeated. The botanical characteristics of that plant were then examined, using similar variety ‘Daiichi-MP21-140-3’ for comparison. As a result, it was concluded that this  Petunia  plant is distinguishable from any other variety, whose existence is known, and is uniform and stable in its characteristics. 
     The new variety of  Petunia  plant was then named ‘Sunpetu 1072’. 
     SUMMARY OF THE INVENTION 
     This new variety is unlike any  Petunia  commercially available as evidenced by the following unique combinations of characteristics. 
     1. Vigorous and trailing habit. 
     2. Abundant flowering, the entire bush remaining in bloom for a considerable period of time. 
     3. Double, small sized and light greenish yellow colored flowers. 
     The new variety ‘Sunpetu 1072’ differs from the similar variety ‘Daiichi-MP21-140-3’, which was applied for Japanese plant variety protection (the application number: 26282; the application date: Sep. 8, 2011; the registration number: 22219; the registration date: Jan. 28, 2013 ), in the following points. 
     1. The leaf shape of ‘Sunpetu 1072’ is ovate. That of ‘Daiichi-MP21-140-3’ is elliptical. 
     2. The flower diameter of ‘Sunpetu 1072’ is somewhat small (about 5.5 cm). That of ‘Daiichi-MP21-140-3’ is small. 
     3. The main color of surface of corolla lobe of ‘Sunpetu 1072’ is light greenish yellow (RHS 1B). That of ‘Daiichi-MP21-140-3’ is YELLOW-GREEN (RHS 150). 
     This new variety of  Petunia  plant ‘Sunpetu 1072’ was asexially reproduced by the use of cuttings, and homogeneity and stability thereof were confirmed. The instant plant retains its distinctive characteristics and produces true to type in successive generations. 
    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
       The depicted plants had been reproduced by the use of cuttings and were photographed during October 2013 while growing outdoors in wall pots with about 24 cm of container size at an age of approximately 5 months. 
         FIG. 1  is a photograph of a typical plant of the new variety of  Petunia  plant ‘Sunpetu 1072’ while growing in a pot. 
         FIG. 2  is a photograph of a close view of flowers of the new variety of  Petunia  plant ‘Sunpetu 1072’. 
     
    
    
     DETAILED BOTANICAL DESCRIPTION 
     In October 2013, the cultivation of the seedlings was repeated at Higashiomi, Shiga, Japan. The average day temperature was about 23° C., and the average night temperature was about 13° C. The plants were grown under natural sunlight. The number of days to flowering (response time) was 2-3 weeks. The quality was maintained for about 150 days. The plants had temperature resistance to about −5° C. (the lowest temperature) and about 35° C. (the highest temperature). Further, the plants had good tolerance to pests and pathogens. 
     For the parentage information: The female parent ‘MP22-176-1’ (unpatented) used in the crossing of ‘Sunpetu 1072’ is a strain of the applicant&#39;s breeding lines (i.e., proprietary selection of  Petunia×hybrida ), having yellow petals; and the male parent ‘MP22-138-2’ (unpatented) used in the crossing of ‘Sunpetu 1072’ is a strain of the applicant&#39;s breeding lines (i.e., proprietary selection of  Petunia×hybrida ), having white petals. 
     For the propagation information: Approximate soil and/or air temperature was around 15-20° C.; the new cultivar was propagated by cutting; number of days to initiate roots was about 7 days;. number of days to produce a rooted young plant was about 21 days; free-root branching; root color was white; and root texture was fibrous. 
     The botanical characteristics of the new and distinct variety of  Petunia  plant named ‘Sunpetu 1072’ at an age of approximately 5 months are shown in the following Table. In the following description, the color-coding is in accordance with the Horticultural Colour Chart of The Royal Horticultural Society, London, England (R.H.S. Colour Chart The 5th edition 2007).
