“…In some other previous works, it has also been determined that F 1 crosses performed better than their parents for agronomic traits, such as grain yield and yield components (Coffman & Wiebe 1930;Hathcock & McDaniel 1973;Petr & Frey 1967;Prakash et al 2013), plant height (Coffman & Wiebe 1930) tiller number and biomass (Prakash et al 2013) which all accord with our findings.…”

The benefits of increased hybrid vigor, which often occur crossing unrelated plants or animals, have been recognized for centuries. In this study, hexaploid oat genotypes E44, K1, and A52 belong to A. sativa and A45 belonging to A. byzantina species were crossed. Heterosis, heterobeltiosis and standard heterosis values were calculated for 11 traits on 12 hybrids belong to K1 x E44 cross (ten hybrids), K1 x A45 cross (one hybrid) and K1 x A52 cross (one hybrid) with the parents. According to the results, parents varied for all traits while hybrids were varied for flag leaf length (FLL), tiller number (TN), 1000-grain weight (1000-GW), grain number per panicle (GNP), grain weight per panicle (GWP), single plant grain yield (SPGY) and biomass (B). K1 x A52 cross had the highest plant height (PH, 201.0 cm), TN (22) and 1000-GW (47.1 g). On the other hand, the highest stem diameter (SD, 9.0 mm), flag leaf width (FLW, 4.0 cm), panicle length (PL, 53.0 cm), GNP(98.0) and GWP (3.2 g) were obtained from K1 x A45 cross. However, K1 x E44 cross had the highest FLL (42.7 cm), SPGY (42.6 g) and B (108.7 g) values. Heterosis values of the oat crosses were significant for all traits except stem diameter, flag leaf length and panicle length, while stem diameter and panicle length for heterobeltiosis and plant height and stem diameter for standard heterosis. Heterosis values were ranked between -26.8 and 282.3% while heterobeltiosis values were between -45.6 and 248.0%, and standard heterosis values were between -2.7 and 419.0%. The highest heterosis and standard heterosis values (282.3 and 419.0%, respectively) were determined for SPGY in K1 x E44 population, while the highest heterobeltiosis value (248.0%) was determined for biomass in K1 x A52 population.

Abstract. A gigantic mutant (gig-a) isolated from cv. Hannes is described. The mutant is lush, many-noded and late ripening not reaching, maturity during The late-maturing, gigantic mutants of the common oats are easily observed even by a layman at harvest time. By that time, the broad-leafed (up to 4.5 cm), green mutants are only at the vegetative stage. A mutant plant is especially easy to detect when the normal oats remain low, for instance due to an early summer drought. Being very late, none of the mutant plants seed in Finland, but are selected away from the seed crop every year. Nevertheless, the mutants can be considered to be very common in some seasons (Kivi 1968). This condition is presumably attained by either (1) a segregation of the previous year's overdominant heterozygotes, or (2) this impression may be due to an exceptionally good exposure of the mutants from the rest of the stand owing to seasonal factors favourable to the growth of the mutant. The first hypothesis is discussed in this paper.The present mutant line designated by the name HA 68-2 was established from a single plant of cv. Hannes in 1968. Since very little has been reported about the inheritance of the gigantic oats, HA 68-2 was tried as backcross to Hannes. This proved difficult, however resulting only in a few seeds during the two seasons the cross was attempted.Zillinsky (1959) describes a'monster' mutant in oats, which is very similar to the gigantic ones. His report is apparently the only one about the inheritance of this type of oat mutants.
