Abstract:
... Thirty-four full-sib Pinus koraiensis families were used to evaluate and identify elite P. koraiensis material. Tree height (H) and diameter at breast height (dbh) were assessed. The results from variance analyses showed that familial variance sources for different traits in different growth years were extremely significantly different. The average phenotypic variation coefficients of H, dhb and v ...

Abstract:
... Sorghum bicolor (L. Moench) is a cereal grain and forage crop that is grown across tropical and temperate regions of the world. Sorghum has a complete flower, resulting in self-pollination as the primary form of reproduction, but it is also grown commercially as a hybrid. Consequently, methods of cross-pollination for both breeding and hybrid seed production are important. In sorghum breeding, cur ...

Abstract:
... Soybean aphid (Aphis glycines Matsumura) is a pest of soybean [Glycine max (L.) Merr] in the Midwestern U.S. and southern Canada. Host plant resistance provides an alternative to insecticides for soybean aphid management. Soybean with Rag1 + Rag2 aphid resistance is available commercially but does not protect against soybean aphid biotype 4 colonization. To find sources of resistance to soybean ap ...

Abstract:
... The root rot caused by Phytophthora medicaginis is a major disease of chickpea in Australia. Grain yield loss of 50 to 70% due to the disease was noted in the farmers’ fields and in the experimental plots, respectively. To overcome the problem, resistant single plants were selected from the National Chickpea Multi Environment Trials (NCMET)—Stage 3 (S3) of NCMET-S1 to S3, which were conducted in a ...

crops; genotype; plant breeding; risk; seasonal variation; seedlings; selection intensity; tea
Abstract:
... In breeding a clonal crop such as tea, selection is a two-stage process. In the first stage the highest yielding individual seedlings are chosen; these are then propagated and planted in clone trials in the second stage. A high selection intensity at the first stage risks eliminating most of the superior genotypes. The optimal proportion to be selected depends on the correlation between seedling o ...
