Breeding of The Soybean Varieties, Aged Maturity and Resistant To Rust Disease

Abstract

Rust disease, caused by Phakopsora pachyrhizi, Syd. is one of the many diseases that cause losses and important disease of soybean in soybean producing countries in Asia, Australia, USA and Indonesia. The disease has resulted also it is very significant in economic losses in Taiwan, Thailand, Indonesia, Philippines, Vietnam, and in some parts of China, Japan, Australia, Korea, and India. Experiments Carried out in the field with a randomized block design (RAK) was repeated three times using four genotypes namely POLIJE-2 and POLIJE- 3 for the parent of a high production and a short maturity and varieties Rajabasa and Ring-1 and for the donor parent who have the advantage of rust disease resistance. Crosses performed to Obtain 16 cross offspring consisting of 12 hybrids and 4 parent-shelving results conducted on the experimental pots. Furthermore, 16 genotypes of F1 seeds were planted in the field using a randomized block design (RAK). In the F1 plants with the plant resistance test performed IWGSR method, age maturity pod (R7), the production of seeds per plant, days to flowering (R1) and the number of pods per plant, where the parameter is used as the basis of Unmatched genotypes from crosses. The results of four studies selected Among the Plant selection results in as many as 71 lines, with criteria grain yield per plant ranges between 17-32 grams, peas ripe maturity of 70-76 days after planting and leaf rust resistant disease caused by the fungus P. pachyrhizi, number of pods ranging from 53-160 and weight of 100 seeds ranges from 11-17 g.
