Improvement of some new pea (Pisum sativum L.) Lines by pedigree selection

Pedigree selection method for three pea (Pisum sativum L.) populations i.e. Palmoral x Jaguar (population I), Master-B x Little Marvel (population II) and Master-B x Jaguar (population III) were applied on the base populations (F3) to F6 generation across three selection cycles during four successive winter seasons from 2015/2016 to 2018/2019 at Sids Horticulture Research Station, BeniSuef Governorate, Horticulture Research Institute, Agriculture Research Center, Egypt. Results illustrated highly significant differences among the families for all studied traits in all selection cycles. Both PJ-1 and PJ-6 developing pea lines, possessed the highest for pod yield / feddan, number of pods / plant and plant height as well as each of pod length, number of seeds/ pod and pod weight for PJ-1 line and both surpassed the highest check cultivars, Entesar 1 and Entesar 2. The pea line PL-28 have earliness for flowering and high values in each of pod length, number of seeds/ pod and pod weight with medium yield. Therefore, these lines are recommended as new cultivars. After three cycles of pedigree procedure increased the GCV/PCV% in number of seeds/pod, pod weight and seed yield /plant in pop I, pod weight in pop II and all traits in pop III except flowering and yield which slightly decreased from 91.3, 91.1 and 91 % after the first cycle to 90.4, 89.9 and 89.9% after the 3rd cycle of selection in flowering trait of Pop I, Pop II and Pop III, respectively, and from 85.1 and 87.4% in yield trait of pop II and Pop III, respectively
