Abstract

Crossing between Mentikwangi (aromatic rice variety) and Poso (high yielding upland rice variety) has been conducted. So far, amount of 9 pure of high yielding and aromatic genotypes have been obtained. The objectives of the research were: 1) to evaluate the effect of genotype x location interaction on the yield and yield components of pure lines progeny of crossing between Mentikwangi and Poso, 2) to select pure lines having high yielding across locations, and 3) to select pure lines having high yielding in specific location. An experimental method with randomized completely block design was used in the research. Amount of 13 genotypes (9 pure lines and 4 comparative cultivars) was sown in the field of 8 different locations, namely Cirebon, Purworejo, Tegal, Kebumen, Banyumas, Batang, Kudus, Banjarnegara. The conclusions are as follow. 1. All of the upland rice pure lines perform the good growth and production across 8 different locations. 2. There are genotype x locations interaction on yield components (number of tiller, panicle length, number of grain, and 1000 seed weight) that is showed by changing of the rank of genotypes in different locations. 3. The pure lines which have high yielding across locations are G10 (4,05 t/ha), G19 (4,00 t/ha), G39 (4,18 t/ha), G12 (3.70 t/ha), and G136 (4,10 t/ha). The pure lines having high yielding in a specific location are Situpatenggang (5,40 t/ha) at the fertile locations (Purworejo dan Kebumen).

Abstract

Current research was conducted with the objectives to identify the utmost traits that may be beneficial for the higher productivity of the grains on high protein content genotypes lines by path coefficient. Path coefficient can define coefficient correlation directly and indirectly to gain information about nature relationship between yield component and protein content to grain yield. Research material consisted of 61 selected plants from G39×Ciherang and 66 selected plants from Mentik Wangi×G39 at F4 generation. Plants were planted in Banyumas in May 2011. Number of panicles per plant, panicle length, 1000 g of grain weight, percentage of filled grain per panicle, protein content, and grain yield were correlated by using Pearson correlation and were followed by path coefficient. Number of panicles per plant, panicle length, 1000 g of grain weight, percentage filled grain per panicle, and protein content were used as dependent variable, while grain yield was used as independent variable. The result showed that protein content in both populations was not correlated with all yield components. The numbers of panicles, followed by panicle length, had highest positive direct effect to yield. The number of panicle was a positive mediator variable to yield from another variable.Keywords: correlation, direct effect, indirect effect, mediator variable, path analysis
