Abstract

An evaluation trial was conducted on natural population of walnuts plants collected from high chilling area of Dir Koistan and planted at the Experimental Garden of lkramullah Khan, Drab House, Mardan. Different parameters were collected in 2003 and 2004 to screen out low chilling walnuts for low chilling regions (plains) of NWFP in particular and Pakistan in general. Maximum plant height was presented by MS-18 (22m) and MS-21 (21.67m). Plant spreadth was outstanding in varieties MS-6 (256.7m2). Stem diameter was maximum in MS-21(2.13m). Better yield was produced by MS-I (63.3kg). Weight of nut was prominent in MS 14-(14.8g). Diameter of nut was maximum in MS-18(6.75g). Kernal percentage was dominated by varieties MS-12 (58.21%) and MS-9 (56.67%). Paper thin shell was recoded in MS-17. The thin shell varieties are from MS-9. The walnut varieties have given significantly better performance at low chilling areas. It shows that the varieties have flexible genes and can adopt to low as well as high chilling areas. Hence forth, these are recommended for commercial plantation in the plain areas of the province in particular and the country in general. The superior germplasm of low chilling walnut is under vegetative propagation for distribution amongst the farming community to enhance their socio-economic conditions.
