MITOCHONDRIAL HETEROSIS IN MAIZE
MANY hybrids between genetic pure lines in maize exhibit heterosis. The search for the genetic basis of heterosis has been carried on for many years and by many workers. Despite these efforts, an adequate, specific biochemical explanation of heterosis has not been presented.

Identification of QTLs for Starch Content in Sweetpotato (Ipomoea batatas (L.) Lam.)
Sweetpotato (Ipomoea batatas (L.) Lam.) breeding is challenging due to its genetic complexity. In the present study, interval mapping (IM) and multiple quantitative trait locus (QTL) model (MQM) analysis were used to identify QTLs for starch content with

Evaluation of heterosis and heterosis retention in Bos taurus-Bos indicus crossbred cattle for reproductive and maternal traits in cows [PDF]
Reproductive, maternal and weight traits were analyzed for Angus (A), Brahman (B), Hereford (H), and Nellore (N) straightbred cows; F1 NA; 3/8N 5/8A cows; and four breed composite cows (BANH) at the McGregor Research Station in Central Texas.

Heterosis in Bitter Gourd (Momordica charantia L.) [PDF]
The present investigation was conducted to determine heterosis in 6 lines and 4 tester crosses of bitter gourd, where the six lines used were MC-84 (L1), S-17 (L2), JMC-21 (L3), NDBT-15(L4), VRBT-94 (L5) and Gy-1 (L6) and the four testers were VRBT-6-9 ...

Do rice hybrids have heterosis for insect resistance? A study with Nilaparvata lugens (Hemiptera: Delphacidae) and Marasmia patnalis (Lepidoptera: Pyralidae) [PDF]
: Antibiosis-based resistance to two insect pests of rice, Nilaparvata lugens (Stal) (Hemiptera: Delphacidae) and Marasmia patnalis Bradley (Lepidoptera: Pyralidae), was compared in 11 F-1 hybrids and their parental lines.
