step 3.step one Phenotype
We amassed phenotypic studies about Vida/MTHW0202 RIL people and you can moms and dads person during the three rainfed and two irrigated environments into the 2013?2014 broadening season. Desk step one accounts mode grouped towards the joint, rainfed, and you will irrigated environment for a few characteristics which were collected Victoria local hookup throughout the moms and dads and RIL people. Brand new rainfed grain give RIL indicate is actually thirty five% less than the irrigated RIL grains yield suggest. On the other hand, rainfed produce role faculties take to pounds, thousand-kernel weight, and you can seed matter per head have been cuatro, seven, and you may seven% less than the latest irrigated environment, correspondingly. Conversely, active tiller amount give component RIL indicate is actually 8% high regarding rainfed surroundings compared to irrigated environments.
- Mention. GLDAH, eco-friendly leaf cycle once going, a description of your own stand-environmentally friendly trait.
- * Factor certainly one of RIL mothers and RIL records at the .05 probability peak.
- ** Significant difference among RIL moms and dads and you will RIL records within .01 probability top.
- *** Factor certainly one of RIL parents and RIL records during the .001 chances level.
Grain yield among parents was significantly different (P < .05) in only the rain-fed environments where Vida's grain yield was 6.0% higher than MTHW0202. MTHW0202 had significantly higher (P < .05) seed diameter and seed number per head across, rainfed, irrigated, and combined environments. Vida had significantly higher productive tiller number (P < .01) vs. MTHW0202 in all environments. Vida also had significantly later heading date (P < .001) and maturity date (P < .05) vs. MTHW020 across combined, rainfed, and irrigated environments, but GLDAH was not significantly different among parents in any environment. Thousand-kernel weight was significantly higher (P < .01) in MTHW0202 vs. Vida in the combined and irrigated environments. Vida was significantly taller (P < .05) than MTHW0202 in the combined and rainfed environments.
Significant differences among RIL entry means were also observedbined environment RIL entry means were significantly different for test weight (P < .001), thousand-kernel weight (P < .001), seed diameter (P < .001), seed number per head (P < .001), heading date (P < .001), GLDAH (P < .05), maturity (P < .05), plant height (P < .001), and grain protein content (P < .001) (Table 1). Significant differences among RIL entry means were also observed for thousand-kernel weight (P < .001), seed number per head (P < .001), plant height (P < .001), and grain protein content (P < .001) in rainfed environments. Plant height RIL entry means were significantly different (P < .001) in the irrigated environments. Transgressive segregation was observed in the RIL population for all traits in the combined, rainfed, and irrigated environments, except for GLDAH in the irrigated environments and maturity in the rainfed environments.
3.dos Relationship research
Pearson correlations between traits varied among environments. In the rainfed environments, GLDAH was positively correlated with yield (P < .001, r = .37), test weight (P < .001, r = .47), and thousand-kernel weight (P < .001, r = .38), but was negatively correlated with seed number per head (P < .05, r = ?.20) and heading date (P < .001, r = ?.36) (Table 2). In irrigated environments, GLDAH was positively correlated with test weight (P < .01, r = .25) and thousand-kernel weight (P < .01, r = .24), but was not significantly correlated with yield (Table 2). Seed number per head (P < .05, r = ?.20) and heading date (P < .001, r = ?.39) were negatively correlated with GLDAH in irrigated environments (Table 2). Yield was positively correlated with test weight (P < .001, r = .36) and thousand-kernel weight (P < .01, r = .24), but was negatively correlated with heading date (P < .001, r = ?.31) in rainfed environments (Table 3). Yield was positively correlated with seed number per head (P < .001, r = .33), heading date (P < .05, r = .19), and productive tiller number (P < .001, r = .29), but was not significantly correlated with test weight and thousand-kernel weight in irrigated environments (Table 3).
