Studies on Combining Ability and Inheritance of Major Agronomic Characters in Naked Barley
Kyung-Soo Min ;
Korean Journal of Crop Science, volume 23, issue 2, 1978, Pages 1~24
To obtain basic information on the breeding of early maturing, short culm naked-barley varieties, the following 10 varieties, Ehime ＃ 1, Shikoku ＃42, Yamate hadaka, Eijo hadaka, Kagawa ＃ 1, Jangjubaeggwa, Baegdong, Cheongmaeg, Seto-hadaka and Mokpo ＃42 were used in diallel crosses in 1974. Heading date, culm length and grain yield per plant for the parents,
of the 10X10 partial diallel crosses were measured in 1976 for analysis of their combining ability, heritability and inheritance. The results obtained are summarized below; 1. Heritabilities in broad sense for heading date, culm length and grain yield per plant were 0.7831, 0.7599 and 0.6161, respectively. Narrow sense heritabilities for heading date were 0.3972 in
and 0.7789 in
and for culm length 0.6567 in
and 0.6414 in
These values suggest that earliness and culm length could be successfully selected for in the early generations. Narrow sense heritability for grain yield was 0.3775 in
and 0.4170 in
2. GCA effects of the
generations for days to heading were high in the early direction for early-heading varieties, while for late-heading varieties the GCA effects were high in the late direction. Absolute values for GCA effects in
were higher than in
SCA effects of the
generations were high in the early-heading direction for Shikoku ＃ 42 x Mokpo ＃ 42, Ehime ＃ 1 x Yamate hadaka, Shikoku ＃ 42 x Yamate hadaka and Shikoku ＃42 x Eijo hadaka. 3. The GCA effects for culm length in the
generations for tall varieties were high in the tall direction while short varieties were high in the short direction. Absolute values for the GCA effects in
were higher than in
SCA effects were high in the short direction for the combinations of Mokpo ＃ 42 with Ehime ＃ 1, Yamate had aka and Eijo hadaka. 4. The GCA effects for grain yields per plant in the
generations for varieties with high yields per plant were high in the high yielding direction, while varieties with low yields per plant were high in the low yielding direction. Absolute values of the
GCA effects were higher than the
effects. The combinations with high SCA effects were Mokpo ＃ 42 x Shikoku ＃ 42, Mokpo ＃ 42 x Seto hadaka and Mokpo ＃ 42 x Cheongmaeg. 5. Mean heading dates of the
generations were earlier than those of mean mid-parent. Mean heading date of the
generation was earlier than the
generation. Crosses involving early-heading varieties showed a greater
mid-parent difference than crosses involving late-heading varieties. 6. Heading date was controlled by a partial dominance effect. Nine varieties excluding Mokpo ＃ 42 showed allelic gene action. Ehime ＃ 1, Shikoku ＃ 42, Kagawa ＃ 1 and Mokpo ＃ 42 were recessive to the other tested varieties. 7. The
segregations of the 45 crosses for days to heading showed that 33 cosses were of such complexity that they could not be explained by simple genetic inheritance. One cross showed a 3 : 1 ratio where earliness was dominant. Another cross showed a 3 : 1 ratio where lateness was dominant. Four other crosses showed a 9 : 7 ratio for earliness while six crosses showed a 9 : 7 ratio for lateness. 8. Many transgressive segregants for earliness were found in the following crosses; Eijo hadaka x Baegdong, Ehime ＃ 1 x Seto hadaka, Yamate had aka x Kagawa ＃ 1, Kagawa ＃ 1 x Sato hadaka, Shikoku ＃ 42 x Kagawa ＃ 1, Ehime ＃ 1 x Kagawa ＃ 1, Ehime ＃ 1 x Shikoku ＃ 42, Ehime ＃ 1 x Eijo hadaka. 9. Mean culm length of the F, and F. generations were usually taller than the mid-parent where tall parent were used. These trends were high in the short varieties, but low in the tall varieties. 10. Culm length was controlled by partial dominace which was gonverned by allelic gene(s). Culm length showed a high degree of control by additive genes. Mokpo ＃ 42 was recessive while Baegdong was dominant. 11. The F_2 frequency for culm length was in large part normally distributed around the midparent value. However, some combinations showed transgressive segregation for either tall or short culm length. From combinations between medium tall varieties, Ehime ＃ 1, Shikoku ＃ 42, Eijo hadaka and Seto hadaka, many short segregants could be found. 12. Mean grain yields per plant of the F_1 and F_2 generations were 6% and 5% higher than those of mid-parents, respectively. The varieties with high yields per plant showed a low rate of yield increase in their F_1's and F_2's while the varieties with low yields per plant showed a high rate of yield increase in their F_1's and F_1's. 13. Grain yields per plant showed over-dominnee effects, governed by non-allelic genes. Mokpo ＃ 42 showed recessive genetic control of grain yield per plant. It remains difficult to clarify the inheritance of grain yields per plant from these data.

Jae-Sung Jo ; Jai-Eul Choi ;
Korean Journal of Crop Science, volume 23, issue 2, 1978, Pages 46~53
The parents and F
seeds from the all possible combinations of the diallel crosses among five upland varieties and a low-land variety were grown in green house in winter and also on paddy field in summer. The durations to heading of all F
's grown in green house at winter were shorter than those of their parents mean. The shorter duration to heading was due to dominace was partial. And the non-allelic gene interaction was not significant. But in case that the F
's and the parents were grown on paddy-field in summer. the durations to heading of F
's were various according to the cross combinations and the non-allelic gene interactions were significant.

Shin-Han Kwon ; Jeong-Hae Oh ;
Korean Journal of Crop Science, volume 23, issue 2, 1978, Pages 99~104
This study was conducted to evaluate the yield performance, adaptation and stability of selected 17 local soybean lines, and determine the optimum number of locations and years in testing program. Among 12 lines having high performance than standard variety Bong-Eui, nine lines were better adapted to favorable environments with high stability. while three were adapted to unfavorable environments with instability. The data from over eight locations in a one-year test would be sufficient to evaluate high yielding lines but the accuracy of selection would be increased by testing in three years instead of one.
Studies on the Root Nodule Formation of Soybean Cultivars
Korean Journal of Crop Science, volume 23, issue 2, 1978, Pages 105~112
Earliness of the nodule formation was significantly different among soybean varieties. The numbers of the nodules were much various due to the origins of the soybean varieties and the date of observation. The significant positive correlations were shown between the weight of nodule and soybean yield and also between the weight of nodules and number of nodules but the correlations among the other characters were not significant.

Jung-Hyun Choi ; Jae-Young Cho ;
Korean Journal of Crop Science, volume 23, issue 2, 1978, Pages 126~132
To examine the effects of P.E. film and rice straw mulching on fall grown potato(Shimabara cultivar) in the middle region of Korea, sprouted seed tuber pieces were transplanted with six kinds of mulching treatments on 24th July and harvested on 25th October. P.E. film mulching from transplanting resulted the perfect rot of transplanted seed pieces due to the excessive high soil temperature (noon soil temperature of about 4
continued until the middle of August). P.E. film mulching from 15th September to harvest increased the marketable tuber yields by 35% due to the raising of soil temperature by 1-3
and maintaining of available soil moisture in dry season. Rice straw (whole or cut in 10cm length) mulching lowered the soil temperature in hot season and raised it in cool season and maintained available soil moisture in dry season. Therefore better emergence, growth and yields were induced. Effects of whole straw, whole growing season and thicker mulching were greater than cut straw, half growing season and thinner mulching. 6cm mulching of whole or cut straw during whole growing season resulted the increasing of marketable tuber yields by 56 or 48%.

Korean Journal of Crop Science, volume 23, issue 2, 1978, Pages 150~153
A study was conducted to determine the critical period of weed-free maintenance required to produce maximum soybean yields. Leaf area index(LAI). crop growth rate (CGR), and number of pods per plant were increased with extended weed-free maintenance period. Consequently, maximum soybean yields were obtained when weeds were controlled for more than six weeks, but a relatively high level of ;soybean production was attained with only two weeks of weed free maintenance.
