Abstract

Superior hybrid and CMV tolerant cultivar development requires a pair of high heterobeltiosis parents and both of which are CMV tolerant.  Gene introgression has to be accomplished if the tolerance does not exist in the parents. This research was objected to employ DNA markers and morphological traits on identifying the most resemble BC3 CMV tolerant individuals to their recurrent parents to shortcut the backcrossing cycle. This research used fifteen BC3 populations generated from crosses of hybrid parents PBC1354 and PBC378 with tolerant parents of C1024, C1042 and C1043.  The BC3 populations were previously selected for their CMV tolerance and were characterized by RAPD technique and morphological traits. Selection by means of both RAPD marker and morphological traits identified BC3 individuals 99.9% resemble to their recurrent parent. Genotypes B3A24-20, B3A29-13, B3A29-22, B3B12-13, B3B37-9, B3B12-25, B3C16-5, B3C16-16, B3C34-18 99.9% were similar to PBC378, and  B3D11-8, B3D11-17, B3D38-5, B3E12-17, B3E20-22, B3E31-19  were 99.9% similar to PBC1354.   Those genotypes were both similar to their recurrent parent and tolerance to CMV. The employed strategy shortcut CMV tolerance genes introgression through a backcross breeding.

Abstract

Snake fruit (Salacca zalacca (Gaertn) is a tropical fruit crop that is widely favored by consumers and possesses high economic value. To increase snake fruit production in Bengkulu Province, plant breeding efforts are required to develop superior, location-specific cultivars. Morphological characterization is essential for identifying genotype characteristics that can serve as plant descriptors and facilitate the selection of desirable traits. This study aimed to evaluate the genetic diversity and morphological performance of snake fruit genotypes in Bengkulu Province, Indonesia. Twelve snake fruit genotypes were observed, namely Bali, Pondoh, Condet, Sinase, Lumut, Manggis, Gula Pasir, Hutan, Gading, Manon Jaya, Madu, and Banjarnegara. A total of 27 morphological characters were evaluated. Quantitative data were analyzed using the Student’s t-test. The results revealed considerable morphological variation among the evaluated genotypes. Based on fruit cluster yield components, including the number of fruits per cluster and the number of clusters per plant, genotypes S7 (Gula Pasir) and S8 (Hutan) showed the greatest potential for high economic value. Meanwhile, genotype S6 (Manggis) exhibited superior fruit quality traits, including fruit flesh weight, edible portion, and flesh thickness. These findings indicate the existence of substantial genetic variability among snake fruit genotypes in Bengkulu and provide valuable information for future breeding and selection programs aimed at developing high-yielding and superior-quality cultivars.

Abstract

Hybrid cultivar is one of the best alternative to increase national hot pepper production. However, lacking of local hybrid cultivars resulted in the dependency on imported expensive seeds. The objective of this research is to study heterobeltiosis potential and yield of hybrids generated from crosses of several hot pepper lines. Nine parental lines and their 19 hybrids were evaluated in field experiment at the Pasir Sarongge Experimetal Station of IPB, Cipanas, West Java, in a randomize complete block design with 3 replications. The results indicated that several crosses showed a high potential heterobeltiosis. The cross of CI034 x CI026, CI042 x CI025, dan CI042 x CI026 showed heterobeltiosis value of more than 100%. Most of the crosses revealed an excellent yield for medium fruit type the yield was about 1 kg per plant (CI034 x CIO06), and for large fruit type was 1,8 kg per plant (CI042 x CIO06), in average, which were higher than the yield of Hot Beauty, a commercial hybrid cultivar.   Key words: Heterobeltiosis, Hot pepper
