Abstract

The objective of this study was to estimate correlation, variances, and heritability of agronomic characters of yardlong-bean F3 population derived from crosses between black and striped-black testa. An F3 population consisted 90 plants along with the two parents (20 plants per parent) were planted in unreplicated trial in Hajimena, Rajabasa, Bandar Lampung in 2008. Variables observed included flowering date, fresh-harvesting date, harvesting date, the number of flower stalks per plants,the number of pod per plant, the average number of locules per pod, the total number of seeds per plant, and the weight of 100 seeds. The results indicated that the estimate of genotypic and phenotypic variances and broad-sense heritability were high for all variables observed. The estimates were significant for the correlation between dry-seed weight per plant and the following variables: number of flower stalks per plant, number of pods per plant, the average number of loculs per pod, and the number of seeds per plants. Based on consumer demand and solid fresh peas can be obtained on the genotypes of the number 6, 7, 9, 11, 14, 19, 22, 28, 66, and 67. There are no pods which exceeds 50 cm in length.Keywords: correlation, heritability, variances, Vigna sinensis, yard-long beans

Abstract

This study aims to determine the genetic variance and heritability of yield component and agronomic character of some new plant type (NTP) of rice genotypes planted on two different locations. The research was arranged in randomized complete block design (RCBD) with 12 treatments and three replications as a blok was nested in location (in two locations, i.e.: East Lampung and Tanggamus. The treatment consisted of 10 new type of rice genotypes, i.e.: IPB 3S, IPB 4S, IPB 5R, IPB6R, IPB117-F-7-2-1, IPB 117-F-7-7- 1, IPB 117-F-14-4-1, IPB 117-F-15-4-1, IPB 117-F-20-1-1, IPB 117-F-80- 2-1, and two control varieties, i.e.: Ciliwung and Ciherang. The flowering time, harvesting time, percent of filled grain per panicle, weight of 1000 grains, dray weight of plant, and yield potential have large genetic variability. Plant height, number of tillers, number of productive tillers, flowering time, harvesting time, panicle length, number of filled grain per panicle, number of grain sterility per penicle, percent of filled grain per penicle, weight of 1000 grains, weight of grain per panicle, and dry weight of plant have high heritability. Selection of NPT of rice genotypes was effective because its have wide genetic variability and can be done at an early stage in a character with high heritability.
