“…Of particular note was line Number 75-1 (Table 3), which was 26 days earlier in flowering, shorter in plant height by 94 cm and had nearly equal total seed weight (40 g) to 'Hokuriku No. 4'. In addition, in their study of lentils, Haddad and Muehlbauer (1981) reported that the genetic variances of plant height, days to maturity and yield in the F 4 generation were significantly higher with SSD than with bulking methods. The results obtained using the F 4 generation would not differ greatly from the results obtained using the F 5 generation, as 87.5% of all loci are expected to be fixed by F 4 .…”

The consumption of products made from Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn.) has increased in recent years in Japan. Increased consumer demand has led to recognition of the need for early varieties of this crop with high and stable yields. In order to accomplish this, more information is needed on the genetic mechanisms affecting earliness and yield. We conducted genetic analysis of 3 agronomic traits (days to flowering, plant height and total seed weight per plant) to segregate F 2 and F 3 populations derived from a cross between Tartary buckwheat cultivars 'Hokuriku No. 4' and 'Ishisoba'. Broad-sense heritability estimates for days to flowering, plant height and total seed weight were 0.70, 0.62 and 0.75, respectively, in F 3 population. Narrow-sense heritability for total seed weight (0.51) was highest, followed by heritability for days to flowering (0.37), with heritability for plant height (0.26) lowest. Later flowering was associated with increased plant height and higher yields. From the F 4 generation, we identified twelve candidate plants with earlier maturity and reduced plant height compared to 'Hokuriku No. 4', but almost the same total seed weight. These results suggest that hybridization breeding using the single seed descent (SSD) method is an effective approach for improving agronomic characteristics of Tartary buckwheat.

“…Dramatic effcts of environment (year, location and management) on plant height occur, but these will only affect selection for increased height in the presence of genotype by environment interactions. The bulk popUlation method of breeding and selection has been reported to increase plant height more effectively than the single seed descent method (Haddad and Muehlbauer, 1981).…”

Large germplasm collections of each of pea, lentil, faba bean and chickpea are now maintained and have been described. The range in the morphology of these species for vegetative, root and reproductive characters is surveyed. Current breeding aims for the vegetative characters of growth habit, leaf type, plant height and lodging resistance are reviewed, as are the selection methods in use and the known response to selection. Amongst reproductive characters, the breeding for improved flower and pod retention, for a multipodded habit (either through an independent vascular system or otherwise), and for pod indehiscence is summarized for all four crops. The small amount of work done on root morphology is also reviewed.

“…Lentil ( I ) . Haddad & Muehlbauer (1981) described experiments with three crosses of lentil (Lens culinaris). They compared parents with 30-50 random F, lines from each cross generated by single-seed-descent (SSD) and bulk (BP) methods.…”

How Frequent Are Superior Genotypes in Plant Breeding Populations?

Summary A search of plant breeding literature has produced 69 examples in which reasonable judgements could be made as to potential for genetic advance. The crops covered are all inbreeders (predominantly cereals) or outbred clones. The average potential for genetic advance (roughly 60 % of examples were favourable) seemed to be far higher than would usually be expected and to indicate therefore that excellent new crop varieties should be more frequent than experience suggests. The discrepancy may be partly explained by various biases but the main conclusion is that superior genotypes are indeed fairly frequent but that selection efficiency is too low to take better advantage of them.
