Cucumber is regarded as main vegetable in Indonesian, however its production cannot match the demand and to increase production can be done by increasing diversity and productivity through plant breeding. The estimation of genetic parameters plays an important role in breeding work, therefore the objectives of this study were to obtain the estimated value of the genetic parameters of some cucumber yield components, to determine the important characteristics of cucumber yield components, and to identify cucumber accessions with high potential yield. The study was conducted at AIC UGM, Berbah, Sleman, Yogyakarta. The accessions used were 23 numbers from the AIC UGM collections and 4 controls. The study used a completely randomized design and analyzed with ANOVA. The results showed that the days to ﬁrst harvest, fruit length, fruit weight, fruit diameter, and ﬂesh thickness give high heritability. The number of fruits and potential yield per hectare gives moderate heritability, and seed rendement gives low heritability. Fruit weight, fruit breadth, and ﬂesh thickness were found as the main important characteristics in yield component. Accession number 372 has the earliest ﬁrst harvest date, accession number 329 and 390 have high potential yield/hectare, fruit weight, fruit length, ﬂesh thickness, and fruit breadth.

The high number of soybean's import has led to various eﬀorts to increase soybean production through increasing productivity, expanding planting areas, and improving management. One that can be done in maximizing soybean performance is the application of biological fertilizer such as mycorrhiza because it was able to increase nutrien tuptake and water and even drought tolerance. This study aims to determine the eﬀect of encapsulation of soybean seeds enriched with mycorrhiza and explain the eﬀect of mycorrhiza on soybean growth and yield. This study used three soybean varieties namely Anjasmoro, Grobogan, and Argomulyo which treated with encapsulation + mycorrhiza, mycorrhiza addition, and without mycorrhiza. The observation include number of pods per plant, number of seeds per plant, percentage of ﬁlled pods per plant, seed weight per plant and weight of 100 seeds. Data on seed weight per plant showed signiﬁcantly diﬀerent among varieties and Anjasmoro was the highest. The application of mycorrhiza through seed encapsulation did not improve the soybean performance.

The estimation of yield component genetic parameters is an important step towards plant breeding activities. This research aims to obtain information about yield components that can be used to increase yield of yardlong bean and accessions of yardlong bean for direct use or breeding materials. The research was conducted at Agrotechnology Innovation centre of Universitas Gadjah Mada, located in Kalitirto, Berbah, Sleman, Yogyakarta. The research materials consist of 29 accessions and 5 high yielding varieties as controls arranged in completely randomized design. Each accession was observed morphologically including days to 75% of ﬂowering, days to ﬁrst harvest, pod length, pod diameter, number of pods per cluster, number of pods per plant, number of seeds per pod, weight of 100 seeds, seed length, the diameter of seed, potential yield pods per hectare. Observed data were analyzed with ANOVA followed by the estimation of genetic parameters and principal component analysis. The results showed that almost all traits had a high heritability value, except seed length which had a moderate heritability value. Accessions 113, 134, 135, dan 137 could be considered as the promising candidates based on the earliest days to ﬁrst harvest and highest potential yield.
