Other claims from this paper (15)
- Intervention effect Inbreeding decreased plant height, biomass and seed yield
- Intervention effect Biomass and seed yield were more severely affected by inbreeding than the other traits
- Intervention effect Significant inbreeding depression was observed for every trait
- Intervention effect Single-cross hybrids showed significant heterosis over inbreds for every hybrid and trait
- Intervention effect Mean heterosis of single-cross hybrids over inbreds was 71.7% for plant height
- Intervention effect Mean heterosis of single-cross hybrids over inbreds was 79.9% for biomass
- Intervention effect Mean heterosis of single-cross hybrids over inbreds was 159.0% for seed yield
- Intervention effect Mean heterosis of single-cross hybrids over inbreds was 36.7% for seed oil content
- Intervention effect Mean heterosis of single-cross hybrids over inbreds was 22.3% for 500-seed weight
- Observation Heterosis was greatest for seed yield and least for 500-seed weight
- Association Line per se and hybrid seed yield were positively correlated (r = 0.72)
- Observation The highest yielding inbred lines LN-97 and LN-98 produced the highest yielding hybrid LN-97 x LN-98
- Recommendation Seed yield of LN-97 x LN-98 might be increased by using LN-99 as a donor
- Recommendation Seed yields can be maximized by using single-cross hybrids
- Recommendation Heterosis of the species can be exploited by using synthetic cultivars
