Abstract

Kutu kebul merupakan hama pengisap daun yang umumnya menyerang tanaman kedelai (Glycine max Merr.) di musim kemarau. Kehilangan hasil akibat serangan hama ini dapat mencapai 80% bahkan gagal panen. Pencegahan dan pengendalian kutu kebul dapat dilakukan dengan prinsip Pengendalian Hama Terpadu (PHT). Salah satu kunci keberhasilannya adalah penggunaan varietas tahan. Di Indonesia, hanya varietas Tengger yang dideskripsikan cukup tahan kutu kebul. Masih sedikitnya varietas kedelai yang tahan serangan kutu kebul membuka peluang bagi pemulia tanaman kedelai untuk merakit varietas kedelai tahan kutu kebul. Informasi mengenai genotipe-genotipe kedelai yang tahan kutu kebul di Indonesia, memberi peluang lebih besar bagi keberhasilan program pemuliaan kedelai tahan kutu kebul. Keberhasilan perakitan varietas kedelai tahan kutu kebul di Turki dan diketahuinya mekanisme ketahanan serta kriteria seleksinya dapat dijadikan acuan bagi pemulia kedelai di Indonesia. Metode pemuliaan single seed descent (SSD) dikombinasikan dengan metode bulk dapat digunakan pada pemuliaan kedelai tahan kutu kebul. Jumlah nimfa per daun atau jumlah infestasi kutu kebul per luasan daun dapat dijadikan sebagai kriteria seleksi.

Abstract

Superior variety with resistance to pest is neededin order to cover the high needs of soybean in Indonesia. Genetic resources from germplasm collections are needed for the assembly of new soybean variety resistant to whitefly. This research aims to find soybean germplasm as the source ofresistance gene and to learn soybean leaf characters resistant to whitefly. This research was conducted from February to May 2018 at Kendalpayak Experimental Station, Balitkabi, Malang. A total of 48 soybean genotypes were evaluated following a randomized block design with three replicates. Observations of whitefly population (number of eggs, nymphs, pupae, and imago), number of leaf trichomes, leaf chlorophyll index, leaf water content, and leaf color score were carried out on three plant samples for each genotype. The result showed that there are 6 resistant genotypes such as Wilis, Meratus, Argomulyo, Ringgit, Merbabu, and Malabar. There were no leaf characteristics that played a doimant role in soybean resistance to whitefly.

Abstract

ABSTRACTGenotype x environment interaction always presents in soybean multilocation trials in Indonesia. The objective of the research was to determine the performance of yield and yield components of soybean promising lines in two locations. A total of 11 promising lines, and three check varieties (Tanggamus, Wilis, and Anjasmoro) were evaluated in NTB and DIY in dry season 2013. The design was randomized complete block design with three replications. The results showed that yield and yield components were influenced by locations, genotypes and genotypes x locations interaction, except for days to maturity which was not influenced by the location. Number of filled pods had a significant positive correlation with grain yield of soybean. TGM/Anj-773 line had high average yield at two locations and higher than the check variety (Tanggamus).Keywords: correlation, genotype x environment, Glycine max
