Heterosis dan Heterobeltiosis pada Persilangan 5 Genotip Cabai dengan Metode Dialil
Abstract
ABSTRACT. Kirana, R and E. Sofiari. 2007. Heterosis and Heterobeltiosis in 5 Genotypes of Peppers Using Diallel Crosses. Five genotypes of randomly selected peppers were intercrossed in diallel mating design in the Screen House of Indonesian Vegetable Research Institute on September 2004. Heterosis and heterobeltiosis evaluation were conducted in a field experiment at Indonesian Vegetable Research Institute from March until October 2005 using a randomized block design, replicated 3 times. The results indicated that in general heterosis and heterobeltiosis occurred on plant height, date of flowering, date of fruit set, fruit length, and number of fruits per plant on 4 population of F1 resulted from crossing of 2 x 14, 14 x 30, 17 x 14, and 30 x 14. Therefore the heterosis effect to create F1 hybrid could be expected on the 4 genotypes of F1. Positive heterosis for plant height range from 1.84 to 25.41% with heterobeltiosis range from 1.63 to 20.78%. For flowering date, negative heterobeltiosis occurred with value ranging from -9.18 to -0.19%. Fruit weight and fruit number per plant heterosis occurred successively 2.27 to 93.40 % and 6.32 to 22.84 %, respectively.
