Abstract

Crossing is one of the breeding programs that can be done to get better plant varieties. Selection is an activity carried out by breeders to determine the seeds that can be planted on subsequent planting. In order to increase the success of selection, segregation need to be determined. The main focus of the study was to determine the frequency distribution and crop segregation. This research was conducted in November 2018 - January 2019 in Agroecotechnopark and Laboratory of Plant Physiology and Breeding, Diponegoro University, Semarang. This studyused F2 seeds from crossing varieties of Fagiola x Aura Hijau. The experimental design was carried out using a single plant design. The results were analyzed using distribution suitability test and chi-square test. Characters that have a normal distribution are plant height, number of leaves, length of pods, and sweetness. The character that is not normally distributed is pod weight. There are two genes that are dominant-recessive epistasis controlling pod weight.

Abstract

Rice is one of the important plants being a staple food for almost the whole Indonesians. Upland (Gogo) rice can be increased by extensification using coastal sandy land. The upland cultivation techniques on the sandy land need an appropriate method to obtain high growth and production. This study aims to examine the effect of tillage on sandy land toward the three upland rice (Oryza sativa L.) varieties to rice growth and production. This study was conducted using a 3 x 3 split-plot experiment with a Randomized Block Design (RBD) consisting of 4 groups. The tillage methods as the main plot are J1: without tillage, J2: partially tillage, J3: fully tillage. The rice varieties as the subplots are P1: inpago, P2: inpago 10, P3: inpago 12. The observation parameters are plant height, number of tillers, the age of panicles appear, number of panicles, plant wet weight, plant dry weight, net assimilation rate, number of grains per panicle, grains production, the weight of 1000 seeds, harvest index, and the percentage of the filled grains. The result of the study shows that the tillage method has a real and significant effect (P<0, 05) on Upland rice growth and production. The inpago 8 variety without tillage was able to produce the highest dry weight and 1000 seeds. The highest grain production was in the partially tillage method. The inpago 10 variety in the partial tillage method was able to produce the highest number of grains per panicle, grains production, 1000 seeds weight and harvest index.  However, in the partial tillage method, inpago 12 variety was able to produce the highest grains per panicle, grains production, 1000 seeds weight and harvest index while without tillage method produced the highest dry weight and the highest filled grains percentage.

Watermelon (Citrullus lanatus) is a widely consumed and cultivated fruit in Indonesia, cherished for its numerous benefits, high economic value, and short plant life. To enhance watermelon quality, plant breeding is employed, aiming to develop superior hybrid varieties. This study, conducted between September and November 2022 on PT. Aditya Sentana Agro's experimental land, evaluated candidate hybrid watermelon varieties (codes 3078, 3079, 3080, 2844, 2845) against comparison varieties (Winda, Mardi, Black Panther, Palguna). Using Randomized Complete Block Design (RCBD) with one genetic factor at 9 levels, repeated 3 times, a total of 27 experimental units were established, each consisting of 10 plants, summing up to 270 plants. Qualitative variables such as fruit skin color, pattern color, flesh color, and shape, along with quantitative variables like fruit weight, length, diameter, dissolved solids, flowering day, skin thickness, and percentage of fruit damage, were observed. The research revealed variations in fruit weight, length, diameter, dissolved solids, and flowering day among the different varieties. Promising candidates for new varieties were identified as codes 2845 and 3078 based on these quantitative traits. This study contributes valuable insights into the potential advancements in watermelon breeding, emphasizing the importance of selecting varieties with desirable characteristics for improved agricultural outcomes.

Abstract

The germination phase of sugarcane is a pivotal stage crucial for successful cultivation. Seeds derived from six to eight-month-old gardens, obtained from protrusions of sugarcane stems, are employed. These seeds exhibit characteristics of dormant buds, contributing to their suitability for germination. A single sugarcane stem typically harbors a minimum of 13 buds, and the selection of seeds with 2-8 eyes per spike is customary among farmers. However, excessive bud usage may lead to abnormal seed growth, underscoring the importance of careful selection. The study employs the rase cage test system, dividing the sugarcane stem into upper, middle, and bottom sections to determine the optimal bud quantity in each treatment. The research investigates the response of different parts of sugarcane bud chip stems to varying concentrations of coconut water growth regulator during germination. Utilizing a factorial randomized block design, the study comprises two factors: Bud chip (BA: Upper Stem, BT: Middle Stem, BB: Bottom Stem) and coconut water growth regulator concentration (Z1: 25%, Z2: 50%, Z3: 75%, Z4: 100%). Positive control involves Agrogibb at a concentration of 120 ppm, with all treatments soaked for six hours. Conducted at the Indonesian Sugar Plantation Research Center on January 10, 2023, the study reveals that the BBZ1 treatment significantly affects the observed parameter of shoot emergence, with an average of 8.1 days. Conversely, the BAZ1 treatment exhibits the fastest and most efficient shoot emergence, with an average of 5.1 days, outperforming other treatments. These findings underscore the importance of careful selection and treatment in the germination phase for optimal sugarcane productivity.
