Maintaining and Improving Peas (Pisum sativum L.) CV. Master Pea (Local Cultivar) Using UPOV Descriptor and Multivariate Analysis in the Vegetable Seed Production Field

Although peas cv. master pea was registered more than 25 years ago in Egypt, this variety showed a remarkable superiority over the varieties grown all governorates of Egypt terms production, quality, and environmental adaptation to climate changes. This study intends assess cultivar's genetic traits, determine degree its deterioration time develop an appropriate plan for maintenance, improvement, conservation strategic withstand changes climatic conditions Egypt. Many types research have been conducted on production new lines Egypt; yet there is dearth multivariate analysis as technique that can combine variances examined qualities using statistics rely algebra matrices extract statistical markers from which researcher make selection program within cultivars without causing erosion. The present experiment achieve following objectives: monitor performance growth traits Master cultivar UPOV descriptor; evaluation yield characteristics, seed yield, quality descriptor. In study, one most important results obtained phenotypic diversity population (measured descriptor) aspect reflects ability environment. Natural - many inherited countries societies affects among individuals population. It be concluded identified descriptor data show differences between cultivars. Therefore, we recommend taking advantage successful way obtain relationships conservation, improvement programs ancient promising Arab Republic
