Evaluasi Hibrid Hasil Persilangan Mangga Arumanis-143 Dengan Tiga Kultivar Mangga Merah Berdasarkan Karakter Buah

Abstract

Evaluation of Mango Hybrids Derived from Crossing of Arumanis-143 with Three Red Mango Cultivars Based on Fruit Characters. Karsinah, Rebin, and Lukitariati Sadwiyanti. In order to improve the character of mango cv. Arumanis-143 that has green-skinned fruit to become red one, Indonesian Tropical Fruits Research Institute Solok had mainactivity, i.e. crossing between Arumanis-143 with Cukurgondang red clones. The objectives of this research were to evaluate the hybrids of mango cv. Arumanis-143 crossing with three red mango cultivars based on fruit characters, and to get 1–2 new superior varieties candidate that had taste like Arumanis-143 with red/attractive fruit skin color. The research was conducted at Cukurgondang Experimental Field, Pasuruan, East Java from June to December 2011. Plant materials used were four cultivars of parents i.e. Arumanis- 143, Irwin, Gedong Gincu, and Saigon, and 27 hybrids from crossing between Arumanis-143 with Irwin, Arumanis-143 with Gedong Gincu, and Arumanis-143 with Saigon. The results indicated that there were 10 hybrids of 27 hybrids having bear fruits i.e. four hybrids from crossing between Arumanis-143 with Irwin, four hybrids from crossing between Arumanis-143 with Gedong Gincu, and two hybrids from crossing between Arumanis-143 with Saigon. The fruit shape of four hybrids from crossing between Arumanis-143 with Irwin were elliptic, fruits size varies with the smallest fruit weigh was F1-09 i.e. 202 g and the largest was F1-14 i.e. 443 g, fruits taste were sourish sweet-sweet, and the fruits skin color were green-yellow. Fruit shape of four hybrids from crossing between Arumanis-143 with Gedong Gincu were elliptic, fruit size varies with the smallest fruit weigh was F1-87 i.e. 281 g and the largest was F1-18 i.e. 519 g, fruits taste were vapidness sweet-very sweet, the fruits skin color were green-orangish green. The fruit shape of two hybrids from crossing between Arumanis-143 with Saigon were elliptic, fruit weigh of F1-45 was 141 g, fruit taste was sweet with yellowish-red fruit skin color and F1-49 was 232 g, fruit taste was sweet with yellowish green fruit skin color. Result of hibrids evaluation indicated that there was a new superior variety candidate that has taste like Arumanis-143 with yellowish-red fruit skin color
